Libyan officials say they're investigating the death of Saif al Islam Gaddafi, the son of the country's late dictator Muammar Gaddafi, and said they were searching for suspects. Gaddafi's office said four masked men stormed into his office before killing him, although that version of events has been disputed. He was convicted of war crimes in 2015 and then freed in an amnesty. #Lybia #SaifGaddafi #MuammarGaddafi #Channel4News #C4New
