2045 GMT: Doctors have suggested that regime forces in Yemen used a form of nerve gas on pro-democracy protesters in Sanaa in a violent clash on Tuesday night.
The soldiers fired warning shots into the air before shooting gas and, it is claimed, live bullets into the crowd, killing one and injuring at least 75.
“The material in this gas makes people convulse for hours. It paralyzes them. They couldn’t move at all. We tried to give them oxygen but it didn’t work,” said Amaar Nujaim, a field doctor who works for Islamic Relief.“We are seeing symptoms in the patient’s nerves, not in their respiratory systems. I’m 90 percent sure its nerve gas and not tear gas that was used,” said Sami Zaid, a doctor at the Science and Technology Hospital in Sanaa.
Mohammad Al-Sheikh, a pathologist at the same hospital, said that some of the victims had lost their muscular control and were forced to wear diapers.
“We have never seen tear gas cause these symptoms. We fear it may be a dangerous gas that is internationally forbidden,” Al-Sheikh said.

Regime and opposition forces have blamed each other for the incident. An opposition spokesman said several oil installations in the town of Ras Lanuf are on fire after being bombed by regime planes.
Representatives of the opposition National Transition Council have met French President Nicolas Sarkozy in Paris and Swiss President Micheline Calmy-Rey in Geneva.

We need to re-group, mass up, and re-capture it again. We've been letting Tahrir down, folks. It's that simple."The Army's operation followed an attack on the protesters by hundreds of men reportedly carrying knives and swords.

0930 GMT: In addition to his State TV appearance early this morning (see 0550 GMT), Libyan leader Muammar Qaddafi gave interviews to Turkey's TRT television and France's La Chaine Info. The two interviews, however, did not exactly fit together:
To TRT: "If Al Qa'eda manages to seize Libya, then the entire region, up to Israel, will be at the prey of chaos... The international community is now beginning to understand that we have to prevent Osama Bin Laden from taking control of Libya and Africa."
To La Chaine Info H"I cannot fight against my people, that's a lie by colonising countries: France, Britain, the Americans. They have suffered (Osama) Bin Laden's interventions, and now, instead of saying that this is an attack against Bin Laden and instead of supporting Libya, no, they want to re-colonise Libya. But this is a colonialist plot, it's colonialist. If al-Qaeda no longer is a common enemy, then from tomorrow we are going to meet Bin Laden and reach agreement with him. He will become our friend if it is considered that this is not terrorism."

The groups called for “resistance [to] escalate peacefully using diversified means across the entire lengths of Bahrain”.
0725 GMT: A Yemeni man has died of injuries after Tuesday's attack by security forces on the pro-democracy camp outside Sanaa University. Almost 100 people were wounded by the assault.
There were other demonstrations on Tuesday. In the southern port city of Aden, a protest denounced the shooting of a young protester, critically wounding him, on Monday.
In the Ibb Province, tens of thousands called on the government to bring to justice those responsible for an attack on Sunday which killed one person and wounded 53.
0715 GMT: In Syria, 12 human rights organisations have called on the regime to end the state of emergency, in effect since 1963, which "affects human rights and public freedoms which are the subject of continuous violations....We call for the lifting of the state of emergency and the release of political prisoners."
Signatories of the statement included the Syrian Observatory for Human Rights, the Syrian League for the Defence of Human Rights, the National Organisation for Human Rights in Syria and the Kurdish Committee for Human Rights in Syria. They also demanded the "amendment of all laws that prevent human rights organisations from working openly and freely, and civil society from playing its role effectively" and called on the government to "enact a law on political parties to enable citizens to exercise their right to participate in managing the affairs of the country".
The groups also asked for judicial reforms and asked authorities to "urgently take all necessary steps to cancel all forms of discrimination against the Kurdish people" who are 9% of the population.
0550 GMT: After teasing foreign journalists for more than 12 hours with the possibility of a news conference, appearing at their hotel n Tripoli but then walking through the lobby and out a side door, Libyan leader Muammar Qaddafi popped up on State TV just after 4:30 a.m. local time (0230 GMT). He declared that "misguided and mad groups" are responsible for the continued violence in the country and that the opposition has been brainwashed by Al Qa'eda.
It was a Tuesday which was dragged out on several fronts. Regime forces maintained their siege of opposition positions in Zawiyah in the west (see separate entry for a striking video report by Alex Crawford of the situation) and in Ras Lanuf in north-central Libya but were still unable to regain control.
The opposition began the day by asserting that they had rejected a deal offered by Qaddafi's representatives, in which the Libyan leader would step down under certain conditions. They continued it by giving Qaddafi 72 hours to step down, a demand which appeared to have more rhetoric than substance behind its enforcement.
The international community drifted in discussion of a no-fly zone over the opposition-held east Libya but seemed to be moving further away from action. US officials such as Secretary of State Hillary Clinton put out the line that no action was possible without a United Nations resolution, which appears to be a distant prospect.
In Yemen, at least 75 people were reportedly injured when security forces fired into thousands of protesters camping outside Sanaa University. The violence followed an incident at a large prison in the capital when demonstrating inmates, shouting anti-Government slogans, were met by tear gas. There were reports of deaths and dozens of injuries.
And in Egypt, there were disturbing signs of conflict in the post-Mubarak era. A Coptic Christian man was killed and 15 were injured as Christians protested Hilwan just outside Cairo over the burning of a church last week. Stones were thrown when bystanders, reported to be Muslims, were angered at the blocking of a road by the demonstrators, and witnesses said the military intervened, firing shots into the air.
In Tahrir Square in Cairo, a march for International Women's Day had a disappointing turnout and took a bad turn when the women were accosted by a group of men chanting insults.
