A Reuters correspondent was shown the wreckage of a warplane in the area of Ras Lanuf in eastern Libya that rebels said they had shot down on Saturday.
Reuters correspondent Mohammed Abbas wrote in a brief message from the scene: "I am at the wreckage of the aircraft in Ras Lanuf." He also reported that the faces of the corpses seemed to have been ripped off.
He also said he was shown a Sudanese passport that he was told belonged to the pilot but added that it showed his occupation as accountant. Rebels have accused Libyan leader Muammar Gaddafi of using African mercenaries to fight for him.
There was no immediate official comment on the incident.
