1555 GMT: C.J. Chivers of The New York Times reports:
Rebels in the contested western city of Misurata appeared close to seizing control of the airport from forces loyal to Col. Muammar el-Qaddafi on Wednesday, advancing on the sprawling facility in scores of trucks and battling pockets of Qaddafi soldiers holed up in terminal buildings....
A journalist accompanying rebels who were breaking through the fence on the airport’s southern perimeter saw abandoned Libyan Army tanks and a deserted bazaar formerly occupied by Qaddafi troops. It appeared that many of the soldiers had simply fled.
Rebel commanders in the eastern city of Benghazi were quoted by Western news agencies as saying the Misurata airport had been captured, but it was clear from the sound of gunfire at the airport that pockets of loyalist resistance remained.
The rebel advance on the airport, which lies a few miles southwest of the city, came after days of NATO airstrikes against positions and military equipment held by Qaddafi forces in and around Misurata, which rebel commanders said had weakened loyalists to a point where a ground attack was possible.
The rebels in Misurata first broke through Qaddafi lines west of the city on Sunday, snapping a stalemate that had left Misurata’s roughly 500,000 residents isolated and increasingly in need of food, fuel and medical aid.
1528 GMT: A truly disturbing report from Syria, but one that matches much of the video and eyewitness accounts from the country. An informant from the Syrian Ministry of Defense Special Forces tells France 24 that snipers were ordered to shoot protesters in the head:
"Each officer was to be accompanied by a volunteer sniper [usually a member of a militia or a mercenary]. They were also ordered to position themselves in places from which it would be easy to shoot. They were ordered to aim for the head as soon as they saw a protester. Their goal was to terrify people so they wouldn’t leave their houses."

"Homs is shaking with the sound of explosions from tank shelling and heavy machineguns in the Bab Amro neighborhood," Najati Tayara said by telephone from the city.

0930 GMT: From the Associated Press....
The Obama administration is edging closer to calling for an end to the long rule of the Assad family in Syria.
Administration officials said Tuesday that the first step would be to say for the first time that President Bashar Assad has forfeited his legitimacy to rule, a major policy shift that would amount to a call for regime change that has questionable support in the world community....
Two administration officials said the U.S. worries about a prevailing perception that its response to Assad's repression has been too soft, especially after helping usher longtime ally Hosni Mubarak out of power in Egypt and joining the international military coalition to shield civilians from attacks by Moammar Gadhafi's forces in Libya.
Speaking on condition of anonymity to discuss sensitive internal planning, the officials said Assad has dispelled nearly any lingering hope that he can or will deliver on grandiose pledges of reform he has made since coming to power 11 years ago. After ending decades of martial law last month, his regime renewed its crackdown on peaceful protesters even more aggressively, using live ammunition and arbitrarily arrestoing thousands of people.
"We're getting close," one official said on the question of challenging Assad's legitimacy, adding that such a step would oblige the U.S. and, if other countries agree, the international community, to act.

0620 GMT: Did this article, published last Friday, lead to the expulsion of Reuters correspondent Frederik Richter from Bahrain yesterday?
Along with its business friendly reputation, another casualty of Bahrain's crackdown on anti-government protesters could be its crown prince, seen as more reform-minded than others in the ruling family.
The fading influence of Prince Sheikh Salman bin Hamad al-Khalifa puts at stake efforts to liberalise Bahrain's economy and attract global businesses.
"There is no doubt that the hardliners are in control and that there has been a shift in the internal balance within the regime," said Shadi Hamid, analyst at the Brookings Doha Centre.
The crown prince had advocated dialogue with Sunni-led Bahrain's Shi'ite majority in February to try to defuse tension with mostly Shi'ite protesters who demanded a bigger say in the country's political and economic affairs.
But the dialogue failed to take off and the government decided to impose martial law and clear out protesters, aided by troops from Saudi Arabia and other Gulf allies.
Since then, Sheikh Salman has virtually disappeared from public view and Bahrain's Sunni ruling family appears to be putting his younger brother Sheikh Nasser bin Hamad al-Khalifa more in the spotlight.
0550 GMT: The Yemeni military clashed with a tribe opposed to President Ali Abdullah Saleh on Tuesday, bombing the rural area north of the capital Sanaa.
