http://news.yahoo.com/s/ap/af_libyaAnti-aircraft fire has erupted in the Libyan capital, with volleys of tracer fire arching into the air, marking the start of a second night of allied strikes on the country.
There is no immediate word on the targets in the new round of strikes. The heavy chatter of anti-aircraft defenses began soon after nightfall.
The U.S. military says the first air assault by the U.S. and its allies the night before — including airstrikes by long-range bombers and a shower of Tomahawk cruise missiles — was successful, though it did not fully eliminate the threat from Libyan air defenses.
