Islamic State militants attacked government forces and their Shi'ite militia allies on Saturday near the city of Baiji, Iraq.
Four suicide bombers in vehicles packed with explosives hit security forces and the local headquarters of the Shi'ite militias killing 11 people. The attack comes as the battle for control of Iraq’s biggest refinery continues.
Iraq has been struggling for stability since the last US troops pulled out in 2011, as the battle against Islamic State and extensive sectarian disputes obstruct efforts to rebuild the economy.
