TRIPOLI (AFP) - Khamis, the son of embattled Libyan leader Moamer Gaddafi, has been shown on state television just days after rebels battling the regime reported his death, which Tripoli denied at the time. The broadcaster showed footage of what it said was a visit on Tuesday by the uniformed 28-year-old to a hospital to meet "victims of NATO raids." It was the first time he had been seen in public since August 5, when a rebel spokesman said a NATO attack on an operations centre in Zliten had killed 32 people.
