Attack on Iraqi military base kills at least 15 - sources
Two of the bombers detonated their vehicle-borne explosives at the gate of Camp Speicher, a former U.S. base outside the Sunni city of Tikrit. Three others detonated their explosives after entering the base, the sources said.
Islamic State claimed responsibility for the blasts in a statement distributed by supporters online.
