Mutassim Gaddafi, one of the ousted Libyan strongman's sons, was found dead in Sirte on Thursday, a commander of the new regime forces told AFP. "We found him dead. We put his body and that of (former defence minister) Abu Bakr Yunis in an ambulance to take them to Misrata," said Mohamed Leith, who had earlier confirmed that Moammer Kadhafi had been captured in his hometown and subsequently died of his wounds.
