[ALGERIA, 9 p.m. ET, 3 a.m. local] U.S. President Barack Obama has issued a statement commending Algeria for formally lifting a state of emergency that had been in place since 1992.
"This is a positive sign that the government of Algeria is listening to the concerns and responding to the aspirations of its people, and we look forward to additional steps by the government that enable the Algerian people to fully exercise their universal rights, including freedom of expression, association and assembly," Obama said in the statement, which was released by the White House.
Algeria's move 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.

Six pro-regime soldiers who were captured said they had been told that the city was being run by Arab militants and it was their job to liberate it, according to the doctors, who asked not to be identified. The soldiers added
that they had been misled so that they would fight against their countrymen, the doctors said.
By the end of the day, the situation was calm in the seaside city, they said.

"The leaders discussed the range of options that both the United States and European countries are preparing to hold the Libyan government accountable for its actions, as well as planning for humanitarian assistance," the White House statement said.
U.S. officials have said all options were under consideration, including sanctions and enforcement of a no-fly zone, to try to stop the Libyan government from attacking protesters.FULL STORY ON PROTESTS IN LIBYA

Space shuttle Discovery lifted off from Cape Canaveral, Florida, late Thursday afternoon, beginning what is expected to be its final mission.
NASA had halted its countdown at five minutes due to a computer problem related to safety on the "eastern range." But after a confirmation that all was good to go, the countdown resumed and the shuttle lifted off about three minutes behind its planned 4:50 p.m. ET launch.
The six-member crew will deliver a storage module, a science rig and spare parts to the international space station during its 11-day mission.
The liftoff comes after months of delays due to leaks and cracks in the external tank.
The last scheduled launch of space shuttle Endeavour is scheduled for April 19, and shuttle Atlantis is tentatively scheduled to launch during the summer.
A federal judge is set to formally approve three criminal counts being dropped from the corruption case of former Illinois Gov. Rod Blagojevich, a judicial source in Chicago tells CNN.
The racketeering, racketeering conspiracy and wire fraud charges were part of a broader indictment against Blagojevich, who faces re-trial in April.
The former governor still faces trial on 17 public corruption-related charges. He is accused of, among other things, trying to gain financially and politically as he weighed who to name U.S. senator when Barack Obama was elected president.
The first trial ended in August, when jurors convicted Blagojevich of lying to federal agents on one of 24 counts brought against him by the federal government. They deadlocked on all the other counts, and federal authorities soon thereafter signaled their intent to request a new trial.

Wisconsin state police were dispatched to the homes of several Democrat state senators in an effort to compel them to return to the legislature, said Department of Transportation spokesman Steve Olson.
Fourteen Senate Democrats fled to neighboring Illinois to prevent a quorum from voting on a budget repair bill that would curb the collective bargaining rights of public sector workers and raise their contributions to pensions and health insurance plans.
Meanwhile, a separate but nearly identical budget bill is up for debate in Wisconsin's other chamber, the state assembly. The assembly lawmakers are poised to vote on the bill Thursday.
The state faces a Friday deadline to balance the budget. Wisconsin faces a $137 million budget shortfall by June 30 and a $3.6 billion gap by 2013.
NASA's shuttle Discovery is scheduled to launch Thursday for its final mission as the shuttle program comes to an end. After months of delays due to leaks and cracks in the external tank, NASA says Discovery is ready.

Turmoil in Libya – It's Day 10 of anti-government protests in Libya. There were bloody clashes Thursday between security forces and demonstrators in Zawiya, a town west of the capital, Tripoli. Seven people have died there, witnesses said. "Blood is all over the streets," a mother told CNN, saying her son had been shot. A witness said the violence began when people who support leader Moammar Gadhafi came into the city square and encountered those who are protesting his ouster.
Speaking by phone Thursday on state TV, Gadhafi blamed the country's violence on young people, who he said were taking drugs and being influenced by al Qaeda. Addressing the situation in Zawiya, he said, "We shouldn't leave (the town) without any control."
After more than three dozen missions, space shuttle Discovery is getting set to call it a day. Join CNN.com Live for live coverage of Discovery's final mission.

10:30 am ET - Pentagon briefing on Afghanistan - ISAF and Afghan military officials brief reporters on current military operations in Afghanistan.
When Melissa Moorhouse got on a Red Line subway train in Boston on January 7, her pet snake, Penelope, was coiled cozily under her scarf.
When Moorhouse got off the train, Penelope, a Dumeril's boa, stayed behind, hiding somewhere in the car, CNN affiliate WCVB-TV reported.
A month passed before another passenger reported seeing a snake on the "T," as the Metropolitan Boston Transit Authority system is called. After another search, Penelope was found, safe and sound, and returned to Moorhouse.
But that's not all the T folks had for Moorhouse. This week she received a $650 bill, she told the station.
"To rid the subway car of any traces of germs such as salmonella, which may have been left by your snake, MBTA maintenance crews had to scrub and disinfect the Red Line car in which your snake was found," MBTA Treasurer-Controller Wesley Wallace wrote to Moorhouse.
Moorhouse didn't think she deserved the bill.
"I understand sanitizing the train, but shouldn't that be done anyway?" she told WCVB. "A lot of different people with a lot of different sicknesses are on that train. People throw up on the train, people bleed on the train. Do they have to pay to get it cleaned?"
The MBTA told Moorhouse she should use a pet carrier if she carries the snake on a train again.
