Islamic State militants drove a tank filled with explosives onto an Iraqi police base Monday, killing at least 37 people and injuring dozens more, Iraqi security officials said.
The suicide bombing near Samarra, northwest of Baghdad and north of IS-held Ramadi, targeted security forces and triggered a secondary explosion in an ammunition depot on the base.
Military and paramilitary forces are using the area as a launchpoint for anti-Islamic State operations.
The U.S.-led coalition continued its air campaign against IS targets overnight, conducting 13 airstrikes in Syria that focused heavily on Hasakah, and 10 in Iraq.
