Two years after the fall of Muammar Gaddafi, we ask why the government struggles to rein in the country's militias. Inside Story, with presenter Jane Dutton, is joined by guests: Larry Korb, a senior fellow at the Centre for American Progress and a former assistant US secretary of defence; Anas el-Gomati, the director of the Sadeq Institute, a non-governmental think tank; and Abdul Monem al-Yasser, Libya's chairman of national security.
