IRBIL: A rocket attack at a US-led military base in Kurdish northern Iraq on Monday killed a civilian contractor and wounded five other people, including a US service member, according to initial reports, the US coalition in Iraq said.
It was the most deadly attack to hit US-led forces in almost a year in Iraq, where tensions have escalated between US forces, their Iraqi and Kurdish allies on one side and Iran-aligned militias on the other.
A coalition spokesman said on Twitter the attack hit coalition forces in the Kurdish regional capital of Irbil, and that more details would follow.
Kurdish security sources said at least three rockets landed near Irbil International Airport in the autonomous region late at night. Reuters reporters heard several loud explosions and saw a fire break out near the airport. Meanwhile, the United Nations Iraq envoy Jeanine Hennis on Tuesday condemned the attacks.
“We deplore the deadly rocket attack on Erbil. Such heinous, reckless acts pose grave threats to stability. Iraq must be shielded from (external) rivalries. We call for restraint and for close Baghdad-Erbil collaboration to bring culprits to justice,” she posted on Twitter.
