An air base in Iraq that hosts US, Iraqi and coalition troops was targeted on Wednesday when several rockets hit the facility, according to a report.
At least ten rockets hit at Ain al-Asad base in Anbar province at 07:20, The Associated Press reported.
According to Reuters, no casualties were reported immediately.
The base was the same as that targeted last February in an attack that left about 100 troops with head injuries, Bloomberg News reported.
Iraqi forces led the investigation into the attack, Col. Wayne Marotto, a U.S. military spokesman, wrote on Twitter.

The rocket occurred a few days after sources told Fox News that the Combined Joint Task Force Operation Inherent Resolve had increased the threat level for U.S. troops serving in Iraq.

U.S. military officials are expecting possible retaliation after President Biden ordered airstrikes in Syria last week.
The US strikes were in response to rockets aimed at the US presence in the region. The AP reported that a coalition contractor from the Philippines was shot dead outside an airport in Irbil, in northern Iraq.

U.S. officials described the Biden-ordered response as “proportional” to the previous rocket fire.
The source of Tuesday’s rocket fire is not immediately known.
The rocket fire also took place when Pope Francis planned a historic visit to Iraq for later this week that would make him the first pope to ever visit the country.
