2115 GMT: A slow evening, probably the slowest since the start of the crisis. There are still reports of "God is Great" from the Tehran rooftops but no evidence of significant public or private shifts.

Some activists are talking of a mass release of green balloons at 1 p.m. local time on Friday, which would be soon after the Supreme Leader has led the prayer service at Tehran University. The Iranian Government, however, continues to throw bureaucracy at the opposition; the Ministry of Interior has informed Mir Hossein Mousavi that a permit for a march will only be issued if one week's notice, in person, is given.

2000 GMT: The BBC has posted the video of its interview with the doctor who tried to save the life of Neda Agha Soltan.

1755 GMT: Presidential candidate Mohsen Rezaei, who apparently had switched sides in the battle with the withdrawal of his complaint over vote fraud, has tacked back today. He has said that the withdrawal of his petition to the Guardian Council is not a withdrawal of people's concerns about the Iranian system. He will pursue the issue of the system's cruelty to people until he "gets results".

1735 GMT: Self-proclaimed geopolitical wizard Thomas Barnett, who conjured an "arc of instability" to help rationalise the 2003 war in Iraq, comes out with this defense of "the devil you know" today: "Ahmadinejad, with his record — again, in Nixon-esque fashion — for doggedly hating the regime's avowed enemies (Israel and America), could likewise employ a Nixonian reversal under the right conditions."

So let me get this straight: instead of working with the Presidential candidate (Mousavi) who said just before the election that he thought the Iranian rhetoric on Israel had been too harsh and that he welcomed international negotiations over any Iranian consideration of a nuclear weapons programme, Barnett prefers that the US work with a President (Ahmadinejad) who has been unremittingly hostile on Israel, who has frustrated his own diplomats, and who has put forth the notion of "Western interference" to deal with issues over his re-election? Idiot.

Sorry, that is inappropriate.

Amoral idiot.

1725 GMT: Report that large number of anti-riot police and paramilitary Basiji are preventing people from stopping at the grave of Neda Agha Soltan.

1720 GMT: Correction: contrary to earlier report (1410 GMT), Seyed Alireza Beheshti, editor-in-chief of pro-Mousavi newspaper Kamaleh, has not been released from detention.

1635 GMT: Who Killed Neda? Javan newspaper, associated with Iran's Revolutionary Guard, has declared that the expelled BBC correspondent, Jon Leyne, hired a "member of the rabble" to shoot Neda Agha Soltan.

1615 GMT: Hezbollah towing the line. Agence France Press reports, "Lebanese militant group Hezbollah on Thursday accused the West of fomenting protests in Iran over this month's presidential election but added that it had no worries about the stability of its main foreign backer."

1525 GMT: We've received reliable information that prominent reformist politicians such as Abdollah Ramezanzadeh, a spokesperson for the Khatami Government, and Mostafa Tajzadeh, Deputy Interior Minister under Khatami, are under mounting pressure "to sign confessions and to appear on state controlled TV programs confessing to spectacular conspiracies against the national interests of Iran, in collaboration with foreign governments". Ramezanzadeh's wife yesterday conveyed her husband's message to the public to disregard any televised confessions that may be extracted from him or other leaders of reform in Iran.

1410 GMT: Report that Seyed Alireza Beheshti, the editor-in-chief of the pro-Mousavi newspaper Kalameh Sabz and the son of the late Ayatollah Beheshti (a key figure in the 1979 Revolution), has been released from detention. Also reported that 66 of the 70 faculty detained after their meeting with Mir Hossein Mousavi yesterday have been freed.

1330 GMT: Reports continue of clashes at Enqelab Square, with protesters setting a bus on fire and trying to push back riot police. Claims that tear gas has been used.

1215 GMT: Some demonstrators have tried to reach the site for today's protest, Vali-e Asr Street at Enqelab Square, but Iranian security forces are trying to block any assembly. Army helicopters are flying overhead.

1145 GMT: Fifteen minutes before today's demonstration was supposed to begin. Both CNN and Al Jazeera are now featuring the statement of Mehdi Karroubi's Etemad Melli Party calling off the memorial march: "Despite all the efforts exerted by the sheikh of reforms [Karroubi] to prepare a site for the mourning ceremony, the ceremony will not take place on Thursday."

1130 GMT: News services are picking up on the latest statement of Mir Hossein Mousavi, posted on his website. He calls on supporters to continue demonstrating but to show restraint. He blames those who rigged the election for the violence and bloodshed. Perhaps most significantly, in looking for clues to future political manoeuvres, Mousavi says his access to others is "highly restricted" and he is under pressure to abandon his demand for an annulment of the election.

1100 GMT: The Effects of the Crisis. Iran's position in Afghanistan may be one of the casualties of the current conflict. CNN's Atia Abawi reports, "Drove by a big poster of Neda in Kabul, across from Iranian Embassy. Pic[ture] of her death and Afghan TV crews interviewing people. Poster of Neda was larger than most presidential campaign posters in the city."

0950 GMT: Tantalising (unconfirmed) story of the morning: "Ali Larijani was threatened [with] impeachment by Ahmadinejad supporters in parliament. Hoseinian,Tehrani, and Resai threatened Larijani [with] censure. Previously Larijani said that its not fair the GC [Guardian Council] supports a candidate [Ahmadinejad]."

0830 GMT: The story, which we noted yesterday, that 70 faculty members were detained after meeting Presidential candidate Mir Hossein Mousavi is now circulating in the mainstream press.

0825 GMT: Ayatollah Montazeri, the one-time successor to Ayatollah Khomeini, has sent a fax to Agence France Presse, warning, "If Iranians cannot talk about their legitimate rights at peaceful gatherings and are instead suppressed, complexities will build up which could possibly uproot the foundations of the government, no matter how powerful." He urged the Iranian Government to set up an "impartial" committee with full power to find a solution to the election crisis.

0815 GMT: He Speaks. Via Fars News Agency, President Ahmadinejad has put himself back in the political arena, blasting Barack Obama for interference in Iranian affairs.

0700 GMT: On the BBC' flagship radio programme, Today, Jeremy Bowen has focused on the news --- which we noted yesterday --- that more than 180 of the 290 members of Parliament invited to President Ahmadinejad's "victory party" did not attend.

0600 GMT: A message on Presidential candidate Mehdi Karroubi's website clarifies the postponement of today's march (see 0500 GMT). A spokesman says the memorial to those killed has been delayed by a week.

2040 GMT: One of the latest postings on Mir Hossein Mousavi's Facebook site: "You have the legal right to protest lies and frauds." A full statement is promised on Mousavi's website.

2005 GMT: Reports that Fazaeh Hashemi, daughter of former President Rafsanjani, has been released from police custody.

1900 GMT: Protests and Arrests. Reports that cries of "God is Great" and "Death to the Dictator" from Tehran rooftops are even louder this evening. Lara Setrakian 0f ABC News (US) writes that all "first- and second-level Mousavi advisors and workers" have been arrested and Mousavi is not allowed to speak to journalists.

1800 GMT: We've just published an analysis on Speaker of the Parliament Ali Larijani's political manoeuvres and whether they might foster a political solution.

1705 GMT: Four members of former President Rafsanjani's family have been released from police custory, but his daughter Faezeh (see 1325 GMT) is still detained.

1700 GMT: Today's pattern, on the lines that we set out this morning (0715 GMT), appears to be of the Iranian authorities getting a "breathing space" by putting a heavy security presence on the streets and in the squares and of the opposition movement considering its next move.

Correspondents inside Iran write of security personnel and paramilitary Basiji in large numbers in Tehran and other cities. Arrests of "reformist" activists and journalists continue, with latest news of detentions of members of the Islamic Participation Front.

There is, however, news of a "sit-in" of up to 10,000 people on Gisha Street in north Tehran.

1445 GMT: A disturbing claim from an activist via Twiter: "Ghalamsnews asks for those injured in recent violence to leave their names and contact number."

This should be considered in conjunction with the claim of the Mousavi campaign, publicised on their Facebook page (see 1335 GMT), that Ghalam News, which had been their website, had been hacked and might now be controlled by others. The possibility is that the message now up on the site is a trap to lure and detain protesters.

1345 GMT: Reports of demonstrators gathering in Vali-e Asr Street, Engelab Square, and Baharaestan.

1335 GMT: Mir Hossein Mousavi's Facebook page is buzzing with information, such as "GHALAMNEWS, the main Newsagency of Mir Hossein Mousavi seems to be hacked". Reports also indicate that Mousavi is asking for volunteers with professional management experience to join his effort.

While I can't be certain, my memory of the numbers indicate Mousavi's pages has added 12,000 supporters in the last few days, taking the current total beyond 80,000.

1325 GMT: More on the move against the family of former President Rafsanjani (0935 GMT). Five members have been detained; it is unclear how many, although Iranian activists have listed Rafsanjani's daughter Faezeh and his granddaughter. The Fars News Agency claim they have been held to protect her against assassination attempts.

Faezeh Rafsanjani is a former member of the Majlis, the Iranian Parliament. She spoke at a Tehran rally last Tuesday.

1315 GMT: Ayatollah Mohammad Yazdi, possibly the strongest supporter of the Supreme Leader and President Ahmadinejad in the clerical establishment, has declared that the establishment has no duty to convince Mousavi of the election's results (text in Farsi).

Ayatollah Yazdi is a member of the Guardian Council. He also, as a reader posted out in an important comment this morning (#2 below), is the leader of the Assembly of Experts: we reported yesterday that the Assembly had supported the Supreme Leader's Friday address, 24 hours before it was delivered, but Yazdi's was the only signature.

1240 GMT: Ayatollah Montazeri, the former successor to Ayatollah Khomeini but now under house arrest, has calle for three days' mourning for slain protestors.

1225 GMT: Summaries of former President Khatami's statement have appeared. Warning of the "dangerous" consequences of banning public demonstrations, he has argued that the Law and Constitution must be respected: "The people are the Government."

Latest reports of arrests: activist Shahab Talebani, newspaper editor Mohammad Ghoochani, National Front Party memberKourosh Za'eem.

BBC correspondent Jon Leyne has reportedly been ordered to leave the country.

1050 GMT: Ahmadinejad appears! Iran State News Agency is carrying the President's statement, "tell[ing] U.S and Britain to stop interfering in Iran's internal affairs".

Former President Khatami has also issued a statement about yesterday's events --- we are looking for an English translation.

1045 GMT: The Autobus Workers Union of Iran (Sendikaye Sherkat Vahed) has issued a declaration, asking that 26 June be a day "to ask all our fellow workers to struggle for the trampled rights of the majority of the people of Iran".

1040 GMT: CNN correspondent claims that final examinations at Azad University indefinitely postponed after 200 students refused to take them.

1010 GMT: An interesting move, either by Speaker of the Parliament Larijani or by State authorities representing his position. Balancing his internal criticism of the Government (see 0745 GMT), Larijani "has called for ties with Britain, France and Germany to be reconsidered in view of their 'shameful' statements". According to State media, Larijani mades the comments in a speech to the Iranian Parliament, the Majlis.

Shrewd readers of Iranian politics will note that, while Larijani also called US remarks "shameful", he did not call for a reconsideration of Iran's relations with Washington.

1000 GMT: State media is now taking the line of 10 deaths in yesterday's violence, all of them caused by "hooligans".

0935 GMT: CNN correspondent reports, "Faezeh Rafsanjani, daughter of Ali Akbar Hashemi Rafsanjani, was arrested Sat[urday] in Tehran, her brother said."

0925 GMT: Iran State media has now withdrawn the claim of "several" killed in the mosque fire yesterday.

0900 GMT: A bit of house-keeping: our video page was becoming overloading. It's now been split into Latest Video (the "Neda" videos of 20 June) and Archive Video.

0835 GMT: Definitely a State counter-attack in the media through allegations of extremism/terrorism. Latest claimed assaults are upon two petrol/gas stations and a military post.

(Press TV's website is lagging behind the campaign, however. Its main headline still is, "Calm Returns to Tehran Streets".)

0820 GMT: Sky News passes on the latest line from Iran's state media: "several people" killed by demonstrators in an attack on a Tehran mosque yesterday (see yesterday's update for initial references to the incident).

0757 GMT: Foreign Minister Manouchehr Mottaki has been brought out to give a lengthy, standard defence of the Presidential vote: it was well-organised, there is no chance of systematic fraud/vote-rigging, Western powers should not interfere/criticise, etc.

The statement is not nearly as significant as this question: where is President Ahmadinejad?
!--more-->
0755 GMT: We're just posting a new video of a claimed Saturday night attack on a Basiji headquarters.

0745 GMT: A political development, which depending on events may have lasting significance, that I missed yesterday. Speaker of the Parliament Ali Larijani told Islamic Republic of Iran Broadcasting (IRIB), "“Although the Guardian Council is made up of religious individuals, I wish certain members would not side with a certain presidential candidate."

Larijani's comment not only struck at the unnamed President Ahmadinejad but also challenged Iran's legislature-court of last resort as it supposedly recounted part of the Presidential vote. He has enough status, not only as head of the Parliament but as a former head of the National Security Council, to mobilise opposition "within" the system as demonstrations continue outside it. It also would be useful to know if he has been in contact with another potential challenger, former President Hashemi Rafsanjani.H

Unlike other criticisms that were suppressed Saturday, Larijani's comments were reported on Press TV and the website Khabaronline. (It should also be noted that, during the week, Larijani pressed for and got a nominal Ministry of Interior investigation of the raids by security forces on Tehran University that allegedly killed up to five people.)

0735 GMT: Today "Neda" may become the symbolic label and image for a movement that is verging on revolution, rather than reform.

"Neda" (the name means voice or message of the divine) was far more than a symbol; apparently she was the woman shot and killed in cold blood by a paramilitary Basiji yesterday as, with her father, she watched the demonstrations. The graphic 40-second video of her death (which is posted, albeit on the "More" page) soon represented the violence and tragedy of yesterday's clashes. Within hours, Iranian activists on Twitter, who had begin using the tag #GR88 (Green 88), also adopted #Neda as the powerful shorthand for their cause.

Morning Update 0715 GMT: Apologies for the later start today --- we're still recovering from the intensity of events yesterday and a very late night.

This has the feeling of a "regrouping" morning, as both the Government and the opposition campaigns assess the marches, the violence, and the political situation. Our immediate reaction is that yesterday was a "score draw". The Supreme Leader and security forces struck first by ensuring there could be no single, large, organised gathering at Enqelab (Revolution) Square, while the Guardian Council fending off the pressure for a meaningful reconsideration of the vote. The opposition challenge rallied, however, both because of the persistence of demonstrators, now scattered throughout the city, and because of a single event: the appearance of Mir Hossein Mousavi at a large rally in Jeyhoon Street.

None of this assessment, however, should overshadow the tragedy of yesterday. The "confirmed" casualty count, based on hospital sources, is 19 dead, but the actual total may be far higher. There were hours of beatings, tear gassings, and panic, as security forces and paramilitary Basiji tried not only to disrupt a major rally but to crush resistance (supported by the effective blackout on media). This may have been supported by a deliberate effort to show the "terrorism" of the opposition through a staged or exaggerated proclamation of an attack at Ayatollah Khamenei's mausoleum.

2350 GMT: An Iranian activist claims, based on this posting in Farsi, that the Assembly of Experts' letter backing the Supreme Leader was issued a day before his Friday address. That would be more evidence of a systematic effort to rally the clerics behind Ayatollah Khamenei, rebuffing Hashemi Rafsanjani.

2152 GMT: CNN, based on Iranian hospital sources, is reporting at least 19 people died in today's violence. The unconfirmed death toll is as high as 150.

2150 GMT: More from the activist who was at today's marches (see 2110 GMT): "All routes to Azady square were blocked & if anyone stopped walking or walking slow [security forces] hit him/her brutally. There was no safe path, people were walking in cycles between all variety of security forces. I think they made fun of people, don't go here, go this way, not that way & for no apparent reason suddenly attacking random people. We tried our best using all known shortcuts for reaching Azady SQ where Mousavi was, but ended up in face to face with IRG [Republican Guard]. They weren't just the ordinary police or motorcycle riot guard, they were soldiers holding MP5 supported by reinforced military cars. We didn't realize for a moment they started shooting at people, the gun's sound was like a toy gun, not loud & the soliders were smiling. I was going to tell Masood they are using fake guns for scaring people! until people started screaming in agony. We ran as fast as we could in the opposite direction, at the same time Basiji bastards started to hit fleeing people. I think I saw 2 or 3 people lying on the ground in blood & IRG started to move them, probably hide them."

2140 GMT: We've posted the English translation of this afternoon's speech by Mir Hossein Mousavi.

2110 GMT: One of the most prominent activists on Twitter has returned from today's marches with this report, "It was a nightmare, I can barely breath & my face is burning, Masood got shot in the arm & Shayan's brother is missing. I don't know where to start with, first they attack our peaecful memorial gathering in front of the university with water gun.The university's doors were closed, we couldn't run everywhere! & then they start shooting tear gas at us. they were so many! riot police, normal police, intel, IRG [Republican Guard], Basij! I managed to scape, but they captured so many people."

2105 GMT: An Iranian activist asks on Twitter, "Why are Rafsanjani and Khatami so silent?" Indeed, apart from Ayatollah Montazeri with his general letter this morning, has any "establishment" figure come out alongside Mousavi with the demonstrators today?

2055 GMT: Twitter sources say that this Mehr News page (in Farsi) summarises the support of the Assembly of Experts for the Supreme Leader's Friday statement. This in turn indicates that the initial attempt of former President Hashemi Rafsanjani to mobilise the Assembly against the election outcome has fizzled out.

2050 GMT: Latest reported arrest is of Mohsen Mirdamadi, the head of the pro-reform Islamic Iran Participation Front.

2005 GMT: Reported arrests throughout the day in Iran, including editors, Mousavi campaign workers, and journalists. The latest reported detainee is Jila Bani Yaghoub, journalist and women's rights activist.

1915 GMT: A few hours ago, we posted a video of a woman "badly injured" by a gunshot in today's demonstrations. The footage is so graphic that we have moved to the "jump page" after the More... tag.

I have just read more information on The New York Times blog about the incident. The woman was a bystander watching events; according to a doctor who witnessed the event, a paramilitary Basiji deliberately fired at her chest. She died within moments of the shooting.

1905 GMT: Tehran Bureau reports, "Hospital close to the scene in Tehran: 30-40 dead thus far as of 11pm and 200 injured. Police taking names of incoming injured."

1900 GMT: Press TV continuing to lead with "police usedbatons, water cannons, and tear gas on protesters", over images of a burning bus in the centre of a Tehran boulevard. It adds, "Reports say clashes are continuing" and "several people have been injured".

Press TV continues to declare " a terrorist attack" at Ayatollah Khomeini's mausoleum although casualty figures have been revised downward to the dead assailant and three injured. No supporting footage is provided.

1835 GMT: President Obama has just released this statement on Iran:

The Iranian government must understand that the world is watching. We mourn each and every innocent life that is lost. We call on the Iranian government to stop all violent and unjust actions against its own people. The universal rights to assembly and free speech must be respected, and the United States stands with all who seek to exercise those rights.

As I said in Cairo, suppressing ideas never succeeds in making them go away. The Iranian people will ultimately judge the actions of their own government. If the Iranian government seeks the respect of the international community, it must respect the dignity of its own people and govern through consent, not coercion.

Martin Luther King once said - “The arc of the moral universe is long, but it bends toward justice.” I believe that. The international community believes that. And right now, we are bearing witness to the Iranian peoples’ belief in that truth, and we will continue to bear witness.

1810 GMT: Tehran Bureau reports, "WHOLE city is shaking with very loud screams from rooftops. Their loud voices calling only for God is filled with fear, hatred, and hope." Lara Satrakian of ABC News: ""People are very angry…they are screaming like a banshee…this ain't aloha [sic] akbar anymore."

"Explosive" shouting also reported in Mashaad.

1755 GMT: Reports of loud shouts of "God is Great" from Tehran rooftops.

Reports of clashes with paramilitary Basiji at Haft Hooz Square. Further claims that demonstrators set fire to a mosque in Tehran and also set alight a bus and several motorcycles.

1745 GMT: The UK's Sky News is currently showing footage of protesters in Tehran seemingly being kicked and beaten. They are streaming a small amount of footage on their frontpage. You may also be able to see the footage by clicking 'Video News Headlines' or 'Watch Sky News Live' in the right-hand bar of their main story.

1725 GMT: The English translation of a  letter purportedly from Grand Ayatollah Montazeri, the designated successor Ayatollah Khomeini before falling out of favour in 1998, has been posted: "A legitimate state must respect all points of view. It may not oppress critical views. I fear that this will lead to the loss of people’s faith in Islam."

1720 GMT: Reports that IRIB 1 [Islamic Republic of Iran Broadcasting] now broadcasting "confessions" from detained protesters.

Also reports that people are blocking streets in east Tehran and setting fires.

1650 GMT: Claims now of fighting in Tehran, Shiraz, Rasht, Tabriz, Ahwaz, and Isfahan.

1645 GMT: We've posted a video which purports to be of Mir Hossein Mousavi addressing a rally in Jeyhoon Street in Tehran this afternoon. If verified, this could be footage of a key point in the development of this crisis.

1600 GMT: Mir Hossein Mousavi's Facebook page has been updated three times in Farsi in the last hour. We're seeking a translation.

1543 GMT: Claims that, in his speech, Mousavi declared the Presidential election "null and void". Claims also that he cast shame upon the Government and declared that he is ready for martyrdom.

1540 GMT: Eyewitness reports, via The New York Times blog, confirm fighting in Shiraz.

1530 GMT: Reports that Mir Hossein Mousavi is now addressing a crowd in Jeyhoon Street, beginning his speech, "We all go back to God."

1525 GMT: Reports of heavy fighting in Khosh St. and claims of shot protester as security forces dispersed people in Khargar Street. Claims that many people are trapped in Azadi Square.

Also reports of fighting in a 2nd city, Shiraz.

1520 GMT: CNN, whose reporters in Tehran are not allow to broadcast without permission of Iranian officials, are going to great lengths to cast scepticism on Press TV's report of the bombing at Ayatollah Khomeini's mosque. At the same time, to offer some coverage, they are playing portions of Press TV English's broadcast.

1505 GMT: Tehran Bureau reports clashes across Tehran, including Vali-e Asr Street, and gunfire and sirens around Tohid Square. It also reports protesters gathering at Vanak Square in north Tehran. There are unverified reports of one demonstrator killed at the crossing of Vali-e Asr Street and Enqelhab Square, and 20 injured protesters transferred to Loghman Hospital in 30 minutes.

There are reports that Mousavi supporters set fire to an Ahmadinejad headquarters.

Tehran Bureau: "The city is boiling over. It's a mess."

1500 GMT: Press TV's hourly lead: "Police have used batons and water cannons to disperse protestors in central Tehran who gathered to hold an illegal rally. Reports say sporadic clashes are continuing....Two helicopters have been seen hovering over the area....Police say a week of protests in the capital have injured 400 forces and done a great deal of damage to public property."

In what is likely to be a significant line, Press TV also emphasized that the Assembly of Combatant Clerics (associated with former President Khatami) had called off the rally after the Ministry of Interior refused a permit. And the station is repeating the morning statement of police commanders that Mir Hossein Mousavi will be responsible for any violence.

Press TV says three people, including the bomber, and eight were injured in the "terrorist" attack on Ayatollah Khomeini's mausoleum in southern Tehran.

1450 GMT: We've posted latest video of the clashes in Azadi Square and off Engelab Square, including BBC footage of shooting, fires, and clashes.

1430 GMT: We're back with the following. The bombing at Ayatollah Khomeini's shrine was reportedly caused by a suicide bomber.

Eyewitnesses reported about 20,000 riot police surround Enqelab Square, armed with rifles, water cannon, and tear gas. Dozens of people were reportedly beaten to force them to leave the square, with security forces reportedly beating passing motorcyclists and even those just passing by. Some demonstrators took refuge in Tehran University.

1325 GMT: We're off to check out some reports. Back just after 1400 GMT.

1317 GMT: Press TV reporting two blasts at Ayatollah Khomeini's mausoleum, with two hurt (Fars News says one dead). Reports that police have closed off Tehran University.

1310 GMT: Twitter report: "In Khosh Street police is attacking people with batons & pepper spray trying to disperse people, shots can be heard around Azadi [Square]."

1300 GMT: Reports of security forces trying to prevent people assembling, chasing them into alleys and allegedly using batons. Demonstrators reportedly trapped between Behboodi and Enqelab Squares.

Reports of gunshots being fired into the air, possibly as warnings. Also reports of tear gas and water cannon being used.

1240 GMT: First pictures coming through from today's march: riot police around square (left).

1230 GMT: Associated Press reports entrance to Revolution (Enqelab) Square blocked by fire engines, with riot police surrounding Tehran University.

1213 GMT: Classic state-run double-speak on Press TV's website. It is still not mentioning today's march. Instead, its story is of the National Security Council warning Mir Hossein Mousavi "against 'the consequences' of backing street rallies". The picture? A very large rally.

1203 GMT: Unconfirmed report "from usually reliable source" to The Guardian of London that Mousavi walking with 10,000 supporters from his party office.

1200 GMT: Witness reports (albeit from before 1130 GMT) that riot police cutting off access to gathering point for march.

1150 GMT: First reports of clashes, with beating of demonstrators near Azadi Square.

1133 GMT: First reports of the march: large numbers gathering, no action by police. Cellphones in area reportedly disconnected.

1107 GMT: Al Jazeera English and Twitter sources report heavy presence of riot police on both sides of Enqelab Square.

1103 GMT: It's On! This message was posted 20 minutes ago on the Facebook page of Mir Hossein Mousavi: "The CRUCIAL Demonstration on Saturday 16:00 in Tehran and all around the world, please spread this message around."

1100 GMT: From one of the most useful Iranian sources on Twitter: "To Western Media: Stop sharing false information given to you by Iranian state television. The demonstration will GO ON. It is NOT canceled."

1045 GMT: As we wait for developments, some interesting thoughts from Gary Sick, one of the foremost US experts on Iran, on the Supreme Leader's address, Mousavi's position, and President Obama's strategy on his blog.

1030 GMT: One hour to the scheduled start of the march. Still awaiting statement by Mir Hossein Moussavi. Reuters reports the statement of Mehdi Karroubi's Etemad-e Melli party, "Because permission was not obtained, the rally today has been cancelled."

1000 GMT: Press TV English interviews Dr Seyed Mohammad Marandi of Tehran University (and a past contributor to Enduring America) about "reports here and there of protests today in Tehran": "Wouldn't this be some kind of defiance of the Supreme Leader's call for calm and peace?"

Marandi replies about "one of the things important things the Leader said yesterday and what most people believe": "It's very hard to imagine vote-rigging where 11 million votes have been manipulated....It's virtually impossible to do that." He criticises Mousavi and Karroubi for their absence from this morning's Guardian Council meeting. "All sides should calm down a bit....Shopowners and ordinary people on the streets want calm. Demonstrations on the part of any candidate...[are] irresponsible."

0930 GMT: Al Jazeera reports that Guardian Council, after its meeting with campaigns this morning, says it will conduct a random recount of "up to 10 percent" of ballot boxes from last Friday.

0907 GMT: Events moving fast. Questions now as pro-Mousavi website (text in Farsi) has announces the withdrawal of support from the Assocation of Combatant Clerics for the rally.

(It should be noted that withdrawals of support also happened on Monday, but in end Mousavi --- who had supposedly backed away from the protest --- appeared at gathering of hundreds of thousands.)

0903 GMT: Al Jazeera English reports from Iran state media that main reformist cleric body, the Association of Combatant Clerics, which includes former President Khatami, say they do not sanction this afternoon's rally.

News agencies are reporting an "important" statement from Mir Hossein Mousavi soon. Al Jazeera also passes on reports that Parliamentary committees are meeting with former President Hashemi Rafsanjani to ask him to take a "greater role" in resolving the crisis.

0900 GMT: A clue to the day? Press TV English reports that Mohsen Rezaie attended this morning's meeting with the Guardian Council but Mir Hossein Mousavi and Mehdi Karroubi did not appear.

0850 GMT: Juan Cole has posted his analysis of the Supreme Leader's Friday address: "The real question is whether this is 1963, when the shah managed to put down a rebellion led by Ruhollah Khomeini, or whether it is 1978-79, when he failed to do so. The answer lies in the depth of support for the protests among the population, and in the stance of the various armed forces toward the latter."

0830 GMT: Reuters, via Iran's Fars News Agency, quotes an Iranian police commander that his forces will deal firmly with "illegal" rallies "beginning today".

0800 GMT: An aide to Mehdi Karroubi has told Agence France Presse that the rally will go ahead.

0705 GMT: There is an intriguing story on Press TV's English website, indicating both that the "inaccuracies" in last Friday's vote may be far greater than the outside figure of "1 million" in "mistakes" cited by the Supreme Leader yesterday and that challenges to the system are coming from candidates across the board, not just Mir Hossein Mousavi.

Presidential challenger Mohsen Rezaei is claiming that he received 3.5 to 7 million votes in last Friday's elections (official returns gave him less than 700,000). A spokesman of the Guardian Council "cautioned" Rezaei against "agitating public opinion".

0700 GMT: Press TV English is making no reference to today's march. Instead, it is still focusing on the Supreme Leader's address from almost 24 hours ago and saying that the National Security Council is "holding Mousavi responsible" for any violence from "unauthorised protest rallies".

The NSC also said that "a network" of agitators responsible to "foreign powers" has been carrying out violence.

0655 GMT: Meanwhile, we are waiting to hear the outcome of a meeting that could have a significant influence on developments. The Guardian Council is seeing representatives of all four Presidential campaigns about the 646 official complaints over the election. On Tuesday, when the Council agreed to hold at least a partial recount, it said the process would take 7 to 10 days.

Morning Update 0630 GMT (1100 Tehran): Five hours before the scheduled start of today's major rally, in Enqelab Square in Tehran, and there are still conflicting stories as to whether it will go ahead. Reuters is still quoting "an ally" of Mousavi who spoke to them yesterday, "Mousavi has no plans to hold a rally tomorrow (Saturday) or the day after tomorrow."

However, Twitter sources inside Iran who have proven reliable continue to publicise the march, quoting former President Mohammad Khatami. Khatami's Facebook page continues to carry the announcement, posted last night, that the demonstration will take place, with Khatami and Presidential candidates Mir Hossein Mousavi and Mehdi Karroubi in attendance.

My guess, following the excellent analysis of Chris Emery yesterday, is that the march proceeds.
