Today's most salient updates from AJE (local times in Libya, GMT+2):
4.17pm: Major General Suleiman Mahmoud, a commander in Libyan army in Tobruk, is now on the side of the Libyan people. He called Gaddafi "a tyrant" and told Al Jazeera "the people in the army are steadfast" in the city.
4.27pm: A Libyan airforce plane has crashed near Benghazi after the crew bailed out, the country's Quryna Newspaper reports. The newspaper said the crew had orders to bomb Benghazi, but refused to carry them out.
5.34pm: Italy predicts that some 300,000 Libyans could flee to Europe "if" Gaddafi falls. The country and five other European nations are trying to prepare for that possibility. They are gathered in Rome to work out a consolidated response if Gaddafi falls. On Thursday, all 27 interior ministers and justice ministers from the EU also plan to meet, Al Jazeera's Harry Smith said.
6.34pm: At least 640 people have been killed since the protests began, the International Federation for Human Rights (IFHR) says. This figure is more than double the official Libyan government toll of 300 dead.
1640 GMT: Protesters in Misurata said they have wrested the west Libyan city from government control, and in a statement on the Internet, army officers stationed in the city pledged "total support for the protesters". The development is significant because Misurata would be the first city outside eastern Libya to fall into the hands of the opposition.
1620 GMT: Lots of chatter that the aircraft carrying Aisha Qaddafi, daughter of the Libyan leader, has been denied landing, first in Beirut, Lebanon, and then in Malta. [AJE: "The plane is said to be headed back to Libya, Cal Perry reports from Valletta."]
1615 GMT: The Libyan Deputy Foreign Minister has warned journalists who have entered the country illegally that they face arrest unless they surrender to the authorities. With the regime's guards leaving the border with Egypt, journalists have been crossing into the eastern part of the country over the last 24 hours. Those areas are in the hands of the opposition; however, there are reports of the regime's mercenaries roaming in the area, especially at night.
