Muammar Gaddafi’s son Hannibal—who has been held in a Beirut jail for seven years without a trial after being abducted by militants—started a hunger strike on Saturday. “He is serious and will continue with it until the end,” his lawyer Paul Romanos told the Associated Press. He’s been detained on charges of concealing information about the disappearance of Lebanese Shiite cleric Moussa al-Sadr on a 1978 visit to Libya, which was ruled by Hannibal’s strongman father at the time.
