2019 K-1 Air Base attack

A rocket attack was carried out on the K-1 Air Base in Kirkuk province in Iraq on 27 December 2019. Who carried out the attack has not been conclusively determined. The air base was one of many Iraqi military bases that host Operation Inherent Resolve (OIR) personnel and, according to the coalition, was attacked by more than 30 rockets. The attack occurred during the 2019–2021 Persian Gulf crisis and preceded a series of events that eventually brought Iran and the United States to the brink of open conflict.
