Developments on unrest in the Middle East and North Africa:

[LIBYA, 9:40 p.m. ET, 4:40 a.m. local] CNN's Tommy Evans took the following photo of people crossing into Tunisia from Ras Ajdir, Libya, on Wednesday. Thousands of people were fleeing Libya due to the unrest and violence there. At this border crossing, Tunisian volunteers greeted people with food and medical care.

[LIBYA, 8:45 p.m. ET, 3:45 a.m. local] CNN's Ben Wedeman, reporting from the eastern Libyan city of Benghazi, which is in opposition control, says an ad-hoc local government has been put in place at Benghazi's courthouse. Citizens have set up committees to collect garbage, protect government property, and ensure an adequate supply of food and medicine.

[LIBYA, 7:22 p.m. ET, 2:22 a.m. local] Aaron David Miller, former Middle East negotiator in the U.S. State Department, writes that there are many good reasons for a careful U.S. approach to Libya, with the Americans-in-Libya factor being just one.

[LIBYA, 6:55 p.m. ET, 1:55 a.m. local] CNN's Ed Henry reports that although U.S. President Barack Obama had taken heat for a relatively muted response in the early days of the crisis in Libya, U.S. officials privately believe it was the best strategy because if Obama had bashed Libya's leader, it could have put the thousands of Americans who are in Libya in harm's way.

[YEMEN, 6:47 p.m. ET, 2:47 a.m. local] Yemeni President Ali Abdullah Saleh is calling for an end to the protests in that country and said he supports the creation of a national unity government to oversee upcoming parliamentary elections, the state-run news service Saba reported Wednesday.

He said that demonstrations must stop to "prepare for a suitable atmosphere" for the elections, and he also repeated his pledge not to run for re-election, Saba reported.

Anti-government demonstrators say that's not good enough. Undeterred by an attack on their sit- a day earlier – when at least two people were killed, according to an opposition lawmaker - anti-government protesters gathered at Sanaa University again on Wednesday to demand that Saleh step down.

[ALGERIA, 6:29 p.m. ET, 12:29 a.m. local] The United States welcomes Algeria's decision to lift its 1992 state of emergency decree "as a positive step," U.S. State Department spokesman P.J. Crowley said in an e-mailed statement.

"We reaffirm our support for the universal rights of the Algerian people, including the freedom of assembly and expression," Crowley said.

Algeria's move, announced yesterday, lifts restrictions on freedom of speech and assembly. Those restrictions were imposed in 1992 to combat an Islamist insurgency. The decision to lift the restrictions comes as Algeria, like other Arab nations, faces waves of protest.

[LIBYA, 6:01 p.m. ET, 1:01 a.m. local] U.S. State Department spokesman P.J. Crowley says via Twitter that a chartered ship that is tasked to evacuate U.S. citizens from Libya's capital to Malta is delayed "due to high seas."

"Citizens are safe on board. It will leave when the weather permits," Crowley's message says.

The ferry picked up U.S. citizens, embassy staff, and some third-country nationals Wednesday at central Tripoli's As-shahab port. The ferry can hold 575 people; it's not clear how many people are on board.

[LIBYA, 5:39 p.m. ET, 12:39 a.m. local] Here is video of U.S. President Barack Obama's statement on Libya.

"There, she'll hold consultations with her counterparts on events throughout the region and continue to ensure that we join with the international community to speak with one voice to the government and the people of Libya," Obama said.

The Human Rights Council, part of the United Nations, is negotiating a resolution on Libya, according to European diplomats who spoke to CNN.

He said Libya "must be held accountable" for its failure to meet its responsibilities. "The entire world is watching," he said.

[LIBYA, 5:09 p.m. ET, 12:09 a.m. local] The United States is doing "everything we can" to protect American citizens in Libya, President Barack Obama said.

[LIBYA, 5:05 p.m. ET, 12:05 a.m. local] The daughter of Libyan leader Moammar Gadhafi, Aisha Gadhafi, tells Libyan state TV that she's heard reports that the United Nations has dropped her as an unpaid goodwill ambassador, but she says she can't verify whether it's true.

"But all the Libyans, who know me and I (know) them, they know that I am the goodwill ambassador with or without the United Nations," she said.

Earlier, the United Nations said it did terminate Gadhafi's daughter's stint as a goodwill ambassador for the U.N. Development Program. U.N. spokesman Martin Nesirky said Aisha Gadhafi was appointed goodwill ambassador for Libya in 2009 to address HIV/AIDS and violence against women in the country. Nesirky said the U.N. agency ended its agreement with her given recent events in Libya.

"Everything will be on the table," she told reporters at the State Department in Washington. "We will look at all the possible options" to end the violence.

"This is now the moment for the international community to act together," she said. The U.S. government "deeply regrets the loss of life" that has occurred in Libya.

Clinton noted that the situation in Libya is "fluid and uncertain" at the moment, and said U.S. authorities are "consulting closely" with representatives of other governments. Clinton stressed that the State Department is encouraging all Americans to leave Libya immediately.

[LIBYA, 3:25 p.m. ET, 10:25 p.m. local] A U.S. chartered ship that is tasked to evacuate U.S. citizens out of Libya will stay in port in Tripoli all night because of bad weather, diplomatic sources say. The ship is expected to leave at some point Thursday morning, the sources said.
