Ailing Libyan agent Abdelbaset Ali Mohmet al-Megrahi, convicted for life over the 1988 Lockerbie bombing, made his first public appearance in nearly two years at a meeting in support of strongman Moamer Kadhafi.
Megrahi, 59, who has terminal cancer, was released from a Scottish jail on compassionate grounds in August 2009. He is the only man convicted over the bombing of Pan Am flight 103 which killed 270 people, mostly US nationals.
Television images showed an emaciated Megrahi on Tuesday, sitting on a wheelchair, at a meeting of his tribe in support of the embattled Kadhafi's regime.
His last public appearance was a September 2009 meeting with African lawmakers at a Tripoli hospital.
The fact that he has survived several months after his liberation has provoked indignation in Britain and the United States. Tripoli meanwhile maintains a news blackout on the state of his health.
