Algerian bomb squads scouring a gas plant where Islamist militants took dozens of foreign workers hostage found "numerous" new bodies on Sunday as they searched for explosive traps left behind by the attackers, a security official said, a day after a bloody raid ended the four-day siege of the remote desert refinery. The official, who spoke on condition of anonymity because of the sensitivity of the situation, said the bodies were badly disfigured and difficult to identify.
