The US launched an airstrike targeting a mid-level al Qaida operative in Libya.
Pentagon spokesman Colonel Steve Warren says the military believes the strike was successful and hit the target, but he did not provide the name of the al Qaida militant.
Col Warren says he does not know where the strike took place in Libya, and it is not known if it was a drone or manned aircraft.
He says there were no US personnel on the ground in Libya for the strike.
Col Warren says the US is still assessing the results of the strike.
