In Libya, NATO blasted Tripoli with a series of air strikes on Thursday, sending shuddering booms through the city. A NATO statement said the attacks hit military vehicle and ammunition depots, a surface-to-air missile launcher and fire control radar. Libyan government officials refused repeated requests for information.The air strikes rained down just hours after NATO and its partners said it would extend the Libyan mission for 90 more days in support of a rebel insurgency.
