BAGHDAD (Reuters) - Islamic State militants attacked an Iraqi army outpost and a police station near the city of Tikrit on Friday, killing at least four soldiers and wounding 12 others, military and police sources said.

The militants used a car bomb and two suicide attackers in their assault shortly after midnight on the army outpost in the town of al-Dour on Tikrit’s outskirts, killing two officers and two soldiers, the sources said.

Gunmen separately attacked the police station a short distance away and set fire to the building before fleeing the area. There were no casualties from that attack, the sources said.
