Iran-backed militants launched ballistic missiles at a base hosting US forces in western Iraq, causing one Iraqi and possible American casualties, the US Central Command said.

“Multiple ballistic missiles and rockets were launched by Iranian-backed militants in western Iraq targeting al-Assad Airbase,” CENTCOM said in a social media post, which placed the time of the attack at 6:30 pm Baghdad time (1530GMT).

Most of the projectiles were intercepted by the base’s air defense systems but “others impacted on the base,” the statement said.

“A number of US personnel are undergoing evaluation for traumatic brain injuries. At least one Iraqi service member was wounded,” it added.
