Libyan rebel forces say they have unconfirmed reports that Moammar Gadhafi’s youngest son was killed in a NATO airstrike early Friday. Khamis Gadhafi, a 27-year-old major commander in his father’s military forces, was allegedly among 33 government troops killed at an operations centre on the western town of Zlitan. NATO confirmed they had been bombing around Zlitan, but would not verify the rebels’ report. Reporters were unable to reach government officials for comment. The Libyan government said in April that one of Gadhafi’s sons and three of his grandchildren were killed in a NATO airstrike on his house in Tripoli.
