Egypt has evacuated diplomats and staff of its embassy in the Libyan capital of Tripoli on Saturday after five staff were kidnapped by unknown gunmen, an Egyptian diplomatic source in Libya told Xinhua. The source, who spoke on condition of anonymity, said that an Egyptian plane left the Tripoli International Airport carrying all staff of the embassy and their families. The Libyan foreign ministry had announced the kidnapping of four Egyptian embassy staff including the cultural attache on Saturday, after another diplomat was abducted on Friday night. The abductions came hours after the leader of the Operations Room of Libya's Revolutionaries, a major militia group, Shaban Hadia, was arrested in Egypt after police forces raided his home in the coastal city of Alexandria. The Islamist militia group contributed to the toppling of former Libyan leader Muamaar Gaddafi during the uprising in 2011
