The son of Libya's late leader Muammar Gaddafi had been kidnapped in Lebanon by militants demanding information about the fate of a Shi'ite cleric who went missing in Libya decades ago.
Hannibal Gaddafi appeared in a video aired late Friday on local TV saying anyone who has information about Imam Moussa al-Sadr should come forward.
Gaddafi appeared to have been beaten up and had black eyes but said in the video he is "in good health, happy and relaxed."
It was not clear when Gaddafi, who is married to a Lebanese woman, was kidnapped.
Al-Sadr, one of Lebanon's most prominent Shiite clerics in the 20th century, vanished, along with two other people, during a trip to Tripoli in 1978. Lebanon blamed the disappearance on Muammar Gaddafi, who was killed in 2011.
