Anti-Libyan Leader Moammar Gadhafi rebel, flashes V sign after capturing the oil town of Ras Lanouf, in eastern Libya, Saturday, March 5, 2011. The anti-Gadhafi rebels fared better elsewhere, capturing the key oil port of Ras Lanouf from regime forces on Friday night, their first military victory in a potentially long and arduous westward march from the east of the country to Tripoli.

Heavy machine-gun fire erupted early Sunday in the Libyan capital of Tripoli, including in the neighborhood of Moammar Gadhafi's residence. Frequent bursts of gunfire and car horns could be heard around the city, beginning at 5:30 a.m. and lasting for several hours, but it was not immediately clear who was firing. An Associated Press reporter said the gunfire was heard near the vast complex where the Libyan leader lives, although it was not known if he was in Tripoli.

MADISON, Wis. (AP) — Liberal filmmaker Michael Moore urged Wisconsin residents Saturday to fight against Republican efforts to strip most public workers of their collective bargaining rights, telling thousands of protesters that "Madison is only the beginning." The crowd roared in approval as Moore implored demonstrators to keep up their struggle against Republican Gov. Scott Walker's legislation, saying they've galvanized the nation against the wealthy elite and comparing their fight to Egypt's revolt. He also thanked the 14 state Democratic senators who fled Wisconsin to block a vote on the bill, saying they'll go down in history books.

RAYNE, La. (AP) — A tornado slammed a southwestern Louisiana town Saturday, killing a young mother who was sheltering her child and injuring 11 other people. More than 100 homes were damaged, many of them destroyed, authorities said, and about 1,500 people were evacuated because of natural gas leaks. Maxine Trahan, a spokeswoman for the Acadia Parish Sheriff's Office, said 21-year-old Jalisa Granger was killed when a tree fell on her house.

WELLINGTON, New Zealand (AP) — The New Zealand government forecasts that two recent earthquakes in the country's second-largest city will almost halve the nation's economic growth this year. The government's Treasury estimated Sunday that a Feb. 22 earthquake that killed at least 166 people in Christchurch and another quake that struck the city in September will slow economic growth by 1.5 percentage points in 2011, to 2 percent. The economy is expected to gather pace again in 2012 on the back of reconstruction work.

WASHINGTON (AP) — When the airline industry took a nose dive a decade ago, executives at global carriers scrambled to find a quick fix to avoid financial ruin. What they came up with, according to federal prosecutors, was a massive price-fixing scheme among airlines that artificially inflated passenger and cargo fuel surcharges between 2000 and 2006 to make up for lost profits.

WASHINGTON (AP) — Restrict abortion or cut spending? The Republicans' "Pledge for America" says the new majority will do both. But negotiations over the federal budget threaten to force the GOP, including its 87 House freshmen, to choose between them.

BARTLETT, N.H. (AP) — Call it an attempt to address an obvious political vulnerability. Republican presidential hopeful Mitt Romney on Saturday derided President Barack Obama's health care law — modeled in some ways after one the ex-governor signed in Massachusetts — as a misguided and egregious effort to seize more power for Washington. "Obamacare is bad law, bad policy, and it is bad for America's families," Romney declared. "And that's the reason why President Obama will be a one-term president." He vowed to repeal it if he were ever in a position to do so, and drew hearty cheers from his Republican Party audience.
