A series of explosions broke out near a military base hosting U.S. forces in northern Iraq, hours after the U.S. military said it had wrapped up its 13th night of strikes against Iran.

A journalist with the Associated Press heard at least seven blasts around 9:30 a.m. local time in the city of Irbil, the capital of Iraq's semi-autonomous Kurdish region, and observed at least four plumes of black smoke rising into the sky from areas near or inside the base after.
