TRIPOLI, Libya (AP) - Angry mobs have set fire to the Italian and British embassies in Tripoli, hours after a NATO missile strike that Libya says killed one of Moammar Gadhafi's sons and three of his grandchildren.
Britain responded to the attack on its embassy complex by announcing that it's expelling the Libyan ambassador to London. The unrest has also prompted the United Nations to pull its international staff out of Tripoli.
Libya denounced NATO's attack on the Gadhafi family compound as an assassination attempt and a violation of international law.
The alliance insists its targets are military in nature and linked to Gadhafi's systematic attacks on the civilian population.
Meanwhile, Gadhafi's forces have stepped up shelling of the besieged western city, pounding Misrata's port, which has been the rebel-held city's only lifeline. Heavy shelling elsewhere in the city left 12 people dead and raised the two-day death toll to 29.
