NATO has resumed airstrikes on the Libyan capital after a brief layoff, hitting several targets late Tuesday. Witnesses say they heard loud explosions in the center of Tripoli and saw plumes of smoke. Libyan state media say the bombings hit civilian sites, and there were reports of casualties. The Libyan capital and its surrounding areas have been the target of regular NATO airstrikes since the alliance started its military operation in Libya in March. Libyan rebels are trying to advance on Tripoli, as the coalition carries out attacks on forces loyal to Libyan leader Moammar Gadhafi. .
