Many are civilians, such as music teachers, pastry cooks and accountants. Replying to the suggestion that the fighters are chaotic, Gheriani says, "That's not fair. A learning curve is taking place right now." br>

After the uprising, the rebels stumbled as they tried to organize. They did a poor job of defining themselves when Libyans and the outside world tried to figure out what they stood for. And now, as they try to defeat Col. Muammar el-Qaddafi’s armed forces and militias, they will have to rely on allied airstrikes and young men with guns because the army that rebel military leaders bragged about consists of only about 1,000 trained men.
2215: A resident of Daraa in southern Syria says, after a day in which 15 people were killed by security forces:"The city is empty, only the army is in the street. Tomorrow we will be more and more in the streets."
2200 GMT: At least 40 people have been killed in clashes between pro- and anti-regime tribesmen in the northern Yemeni governorate of Al-Jawf over the last five days.
Anti-regime tribesmen took over control of the 115th Infantry Division after its commander, Brigadier Abdurabu Hussein, refused to hand over the division to Brigadier Ali Haidara al-Henshi, appointed by President Ali Abdullah Saleh as a replacement.
An official with a non-government organisation said, "Strategic military positions in the governorate are now controlled by anti-government tribesmen and Houthi gunmen. About 20 troops and Houthi gunmen were killed in the latter's attack on the contingent."
2145 GMT: Video from Zintan in northwest Libya, as opposition fighters celebrate atop the regime's tanks and military vehicles. Soon after the filming, the cameraman was killed in the fighting:
I spoke with BBC Radio WM tonight about Muammar Qaddafi and the coalition efforts to remove him from power, talking about the Libyan leader's background and attempting to answer the question, "How long can this go on?"
1957 GMT: Protesters gathered for a fifth day in Deraa, Syria, where authorities have arrested a leading opposition figure, Louai Hussein. The Syrian Observatory for Human Rights said that, "his house was broken into. The door was smashed. His fate is unknown."
Hundreds gathered under very tight security, and the AFP is reporting that their photographer and videographer were attacked by security forces.
Perhaps the most important news, however, is the rumor that the region's governor, Faisal Kalthoum, has been fired, which was one of the demands of the protesters. This has not been confirmed.
1930 GMT: Al Jazeera English's James Bays filed this report earlier today from the front line outside Ajdabiya in eastern Libya. He reports an attack near his position and says, "No one really is making any progress. The opposition are where they were 24 hours ago....They are lightly armed volunteers....A professional officer on the rebel side told me they're very brave but to the point of being suicidal. Gaddafi forces are much more heavily armed. The opposition have the numbers and they seem to have the momentum but on the other side the Gaddafi forces have the power."
1915 GMT: Thanks to James Miller for taking the LiveBlog through the afternoon.
Libyan State TV is claiming live coverage of the capital under fire, with the presenter saying, "Tripoli is being bombarded now." The sky was lit with fire and the sound of anti-aircraft weaponry could be heard.

1920 GMT: Army Officers: Al Jazeera English offers a list of recent resignations and defections by Yemeni officials to the opposition, including six military commanders, dozens of officers, 17 Ambassadors, the entire staff of the Yemeni Embassy in the US except the Ambassador, three MPs, and the leader of Yemen's most powerful tribe.
1910 GMT: President Obama, on a visit to Chile, has spoken to reporters about Chile. He reiterated that "it is U.S. policy" that Libyan leader Moammar Qaddafi "has to go" and the international community "can't stand by with empty words" in the face of an imminent humanitarian catastrophe.
At the same time, Obama anticipated that the US would step back from leading the Libyan military mission when Libya's air defences were disabled: "We anticipate this transition to take place in a matter of days, not weeks."
2145 GMT: Little confirmed information tonight, but several blasts have rocked the Libyan capital Tripoli, with a plume of smoke seen from the direction of Libyan leader Muammar Qaddafi's home in the Bab el-Aziziya compound in a south Tripoli suburb.
1920 GMT: Latest from Libya....
There was a spate of fire from anti-aircraft guns, apparently from nervous troops expecting airstrikes, in Tripoli. The capital is now quiet.
The Libyan military spokesman announced a new ceasefire for 9 p.m. local time (1900 GMT).
An Italian tugboat has been escorted out of port by officials of the Libyan port authority and military. The 11-member crew had been detained this weekend.
2145 GMT: Libyan leader Muammar Qaddafi is now speaking by phone. He says that the coalition attack will launch a second Crusade, which will be countered by the Libyan people. He then asks Africans and South Americans to stand by the regime.
Gaddafi declares that the regime must now open the weapons depots and arm all Libyans. He then ends --- a very un-Qaddafi speech of less than three minutes.
2115 GMT: Activists claim that lawyer Ragia Omran was kidnapped today from a polling station in Egypt during the referendum on the Constiutional amendments.

2105 GMT: Four Al Jazeera journalists have been detained in western Libya.
This morning I had a wide-ranging chat with BBC Radio WM, amidst reports of the regime's advance on opposition-held Benghazi and the international community's discussion of enforcement of a no-fly zone. (At that point, I did not have the confirmed information that a jet had been shot down over Benghazi.)
The conversation took in the latest military situation, the Qaddafi regime's propaganda (including the threat to wield terrorist attacks on "the West"), and my personal opinion on whether foreign support of the Libyan opposition was justified.
The discussion starts just after the 2:06.00 mark.
2055 GMT: Libya's Deputy Foreign Minister has said that the regime has asked Turkey, Malta, and China to send observers to monitor a cease-fire, denying reports that attacks on the opposition were continuing: "The armed forces are respecting [the cease-fire] and will protect civilians."
The King decreed that media must not criticise clerics and praised security forces for blocking protests, "You are the hitting hand against whoever considers undermining the nation's security and stability." He also thanked Saudis for not taking to the streets: "I am so proud of you. Words are not enough to describe you. You are the safety valve of this nation and you struck at that which is wrong with the truth and at treachery with loyalty."
Sweeteners in the King's speech included $66.7bn would be spent on 500,000 housing units, $4.3bn on more medical facilities, an extra $40m for private hospitals, an additional two months' wages for all government workers, and two extra payments for university students worth around $500.
