After weeks of debate, the United Nations finally approved a no-fly zone in Libya, helping rebels fighting Libyan leader Moammar Khadafy at perhaps the last possible moment. Rebels had been driven back by the Libyan army to their last stronghold, the eastern city of Benghazi, and appeared ready to be overrun there as well. Two nights of bombardment by coalition forces have sent the army into retreat, and a missile struck Khadafy's compound in Tripoli, but the final outcome of the conflict is far from clear. Collected here are images from the last few days of fighting. For an earlier Big Picture post on the conflict, see the links below. -- Lane Turner ( 33 photos total
