Lebanon on Wednesday rejected a request by Damascus to return a son of the late Libyan dictator Muammar Gaddafi to Syria, which considers him a "political refugee."

Justice Minister Ashraf Rifi said he was denying the request because Hannibal Gaddafi was a wanted man in Lebanon.

The businessman's son was charged on Monday with withholding information about the disappearance of Lebanese Shiite cleric Mussa Sadr.

Sadr went missing in 1978 during an official visit to Libya, along with an aide and a journalist.

Gaddafi was kidnapped on Friday in Lebanon's Bekaa valley near the Syrian border in mysterious circumstances.

He was freed by police hours later and taken in for questioning, security sources said.
