An Iraqi military base, where U.S.-led coalition troops are based, was hit with 10 rockets Wednesday. This is the latest in a series of rocket attacks in Iraq just days before Pope Francis is due to visit the country.

The rockets targeted Ain Al-Asad airbase, northwest of Baghdad, at 7:20 a.m. local time Wednesday (11:20 p.m. Tuesday ET). Colonel Wayne Marotto, the military spokesman for Operation Inherent Resolve, took to Twitter to confirm the attack.

Iraqi security forces are leading the response and investigation, Marotto added. No one has claimed responsibility for the attack yet. 

There were no immediate reports of any casualties. But CBS News reported that a contractor died of a heart attack after the missile attack. His nationality is unknown. 

The base is the same one that Iran had struck with a barrage of ballistic missiles in January of 2020 in retaliation for the killing of Iranian MG Qassem Soleimani, the Quds Force commander who was responsible for the death of over 600 U.S. troops in Iraq. 

After Iranian-led militias had conducted dozens of rocket attacks on U.S. bases and diplomatic facilities, the U.S. hit the militias with airstrikes. Then Solemani overplayed his hand and had the militias attack the U.S. Embassy. He and the Iraqi leader of the militias were killed in a drone strike soon after leaving Baghdad’s airport. Iran responded with a ballistic missile attack on the Al-Asad airbase. Dozens of U.S. servicemembers were injured with concussions in that strike.

After the missile attack of January 2020, the U.S. moved Patriot missile defense systems onto the Ain Al-Asad airbase. It is unknown if the missiles deployed or if they were successful. 

Iraqi security forces have already found the rocket launchpad used at the attack: a flat-bed truck that was in flames when troops arrived. A picture was posted to Twitter by Mustafa al-Dulaimi (see featured image). The truck was found in the al-Baghdadi area of Anbar.
