TRIPOLI, Libya (AP) - Anti-aircraft fire has erupted in the Libyan capital. Volleys of tracer fire can be seen arching into the air over Tripoli, marking the start of a second night of allied strikes on the country. There is no immediate word on the targets.
The U.S. military says last night's assault, which included strikes by long-range bombers and a shower of Tomahawk cruise missiles, was successful but did not eliminate the threat from Libya's air defenses.
