Developments on unrest in the Middle East and North Africa:
[LIBYA, 10:25 p.m. ET, 5:25 a.m. local] Via Twitter, the U.S. State Department's Bureau of Consular Affairs says U.S. citizens wishing to leave Libya should go to As-shahab Port as soon as possible after 9 a.m. and arrive no later than 10 a.m.
"U.S. government chartered ferry will depart for Valletta, Malta no later than 3 p.m. on Wednesday," the bureau said via Twitter.
Earlier, a senior administration official told CNN that the State Department is chartering ferries to take Americans from Tripoli's As-shahab port to Valletta, Malta on Wednesday.
[LIBYA, 10:18 p.m. ET, 5:18 a.m. local] With the United States unable to land any charter aircraft in Tripoli to fly U.S. citizens our of Libya on Tuesday, the U.S. State Department is chartering ferries to take travelers from Tripoli's As-shahab port to Valletta, Malta on Wednesday, according to a senior administration official not authorized to speak for attribution.
"Tomorrow the question will be if they let the ferry dock. If that happens, our people will flow out," the official said, adding that the reason the charter aircraft didn't land was because the Libyan authorities did not give them permission to do so.
Of the several thousand U.S. citizens in Libya, most are dual nationals; those solely with U.S. citizenship number about 600, State Department spokesman P.J. Crowley said.
The State Department issued a travel alert for non-essential staff to leave the country, an order affecting 35 employees and their families.
Crowley said the airport in Tripoli remained open in "challenging" circumstances. International carriers, he said, were making more seats available for departure.
[LIBYA, 9:32 p.m. ET, 4:32 a.m. local] The video below shows an interview with a Tripoli woman who says security forces there are trying "to not let anyone protest."

[LIBYA, 8:40 p.m. ET, 3:40 a.m. local] A Libyan government spokesman, speaking on television, said U.S. and Israeli intelligence operatives were behind the unrest. "We will get rid of them, in collaboration with our people in the eastern province," he said.
He said Libyan authorities have asked those tribe members who have attacked barracks and police stations to return the weapons they had taken "because security and safety will return to normal." Referring to reports that the military had attacked civilians, he said, "We have reports and evidence they are not using arms unless against those who
attacked the barracks."
[LIBYA, 7:52 p.m. ET, 2:52 a.m. local] Abdul Fattah Younis al Abidi, who confirmed to CNN that he stepped down as Libya's interior minister, says Libyan leader Moammar Gadhafi is "a stubborn man" who will not give up.

"Gadhafi told me he was planning on using airplanes against the people in Benghazi and I told him that he will have thousands of people killed if he does that," Abidi said in an Arabic-language telephone interview conducted Wednesday.
[LIBYA, 6:38 p.m. ET, 1:38 a.m. local] Libya's deputy ambassador to the United Nations, Ibrahim Dabbashi, who on Monday accused Libyan leader Moammar Gadhafi of genocide, told reporters at the U.N. on Tuesday that he again calls "on the regime to stop killing the Libyan people."FULL STORY ON PROTESTS IN LIBYA

Texas lawmakers are weighing a bill that would allow professors and students to carry concealed weapons on college campuses. Before the voting begins, a public meeting on the measure will be announced soon on the legislature's site, searchable by #sb354.
"This is about self-defense," said San Antonio Republican Sen. Jeff Wentworth, the legislation's sponsor. "It's about protecting lives of students who are totally vulnerable and defenseless and able to be picked off by a deranged shooter, as was the case in Virginia."
Wentworth is referring to the April 2007 massacre at Virginia Tech when student Seung-Hui Cho shot 32 people to death. All except two were killed in classrooms in a single on-campus building. Cho committed suicide as authorities approached. He had purchased the handguns used in the massacre legally. (See CNN.com's special coverage of the Virginia Tech tragedy.)
Virginia Tech is the deadliest school shooting in U.S. history. The second-deadliest happened in 1966 when Charles Whitman killed 16 people and wounded 31 at the University of Texas at Austin. A student and former U.S. Marine, Whitman picked off some of his victims from his perch in a campus tower. Most recently in Texas, a student fired an assault rifle in September at the University of Texas. He killed himself, but no one else was hurt.
"The Virginia shooter was mentally deranged. The people who would be able to carry weapons on campus, if this passes, would be licensed, and therefore fully trained," he said. "To get a license in Texas, you have to be 21, go through a 10-hour course and pass an exam, and go out on a shooting range with a handgun and pass a test.
One would have to undergo a criminal background check and pay a fee of more than $100, Wentworth said. "People do not lightly apply for licenses," he said. "We would have responsible, trained people there in the classroom."
Opponents of the bill are concerned that more guns would mean more violence. Critics include two Virginia Tech students who barely escaped Cho's rampage.
"I was there that day. It was the craziest day of my life with one person walking around with two guns," Colin Goddard told reporters last week when he spoke out against the bill at the Texas Capitol. "I can't even imagine what it would have been like with multiple students and multiple guns."
Goddard was shot four times and survived by playing dead. He wrote about his opposition to guns on campus for CNN.com in January.
Former Tech student John Woods, whose girlfriend was killed in the shooting, joined Goddard in Texas to say he, too, is against the bill.
The vast majority of Democrats in the Indiana House have stayed away from the statehouse Tuesday, effectively blocking a Republican-supported bill that would reduce private-sector union rights.
Republicans - who make up 60 of 100 House seats - lacked the two-thirds majority needed for a quorum. Sixty-three lawmakers attended.
Democratic state senators in Wisconsin similarly boycotted their legislature last week to prevent a quorum from passing a budget bill that would increase the costs of benefits to public employees and curb their collective bargaining rights.FULL STORY

The Oscar-winning actor may be attending Sunday night's ceremonies, but a lead story in Newsweek this week is not about his next movie, but his work in the war-torn country of Sudan. Clooney, who was in Sudan a month ago, tells the magazine, which called him a 21st-century celebrity statesman: "Celebrity can help focus news media where they have abdicated their responsibility. We can't make policy, but we can 'encourage' politicians more than ever before."
The dean of Christchurch Cathedral in Christchurch, New Zealand, was in his office when the earthquake hit. The cathedral was heavily damaged, and Beck has called for unity, asking people to help each other out after the tragedy. Sixty-five people have died, and rescue operations are under way for the scores of people who are still trapped.
The mayor of Milwaukee, who ran in the governor's race last fall against now-Gov. Scott Walker, has accused the governor of creating "an ideological war." Barrett gave his "state of the city" speech at the Milwaukee Job Corps Center on Monday, and during the speech defended the Democratic senators who left the state to prevent a vote on Walker's drastic budget-cutting proposal that includes gutting collective bargaining rights for many public employees.
Musician Rufus Wainwright and his partner, Jorn Weisbrodt, have announced the birth of their baby daughter, Viva Katherine Wainwright Cohen. Lorca Cohen, the daughter of musician and songwriter Leonard Cohen, gave birth to baby Viva in Los Angeles on February 2. Wainwright's website outlines how his new four-part family came to be. "In many of the articles announcing the birth of Viva Katherine Wainwright Cohen, Lorca Cohen is characterized as 'the surrogate.' Of course, she is no such thing. She did not carry the child for someone else. Lorca Cohen is the mother of the baby and Rufus Wainwright is the father." Rufus Wainwright is the son of singers Kate McGarrigle and Loudon Wainwright III.
