A US warplane has crash landed in Libya, a US military spokesman says.The spokesman, Kenneth Fidler, told the BBC there was no indication that the F-15 Eagle was brought down by hostile fire.
He said one crew member had been recovered safely. An operation is under way to recovered another.
It is not clear where the plane went down. The development follows a third night of allied air strikes against Col Gaddafi's forces.
Explosions and anti-aircraft fire were heard near Col Gaddafi's compound in the capital, Tripoli.
Fighting between the forces loyal to the Libyan leader and the rebels has also continued, despite the declaration of a ceasefire by the government.
