Several rockets hit an Iraqi air base hosting US forces on Sunday, injuring two foreign contractors and three Iraqi soldiers, the military media center said.

Five rockets struck Balad air base, north of Baghdad, and two of them crashed into a dormitory and a canteen of US company Sallyport, a security source told AFP news agency.

Two foreign contractors and three Iraqi soldiers were wounded, the source added.

Major General Diaa Mohsen, the commander of the Balad airbase, told Iraq's official news agency that one of the security forces injured in the attack was in serious condition. Mohsen said that the base didn't suffer any material damage.

So far, there has been no claim of responsibility for the attack.

Increased attacks on American installations

F-16 fighters are stationed at the Balad air base, and several maintenance companies are present there, employing Iraqi and foreign staff.

In recent months, the heavily fortified Green Zone in Baghdad, home to the US embassy and American troops in Iraq have been the target of repeated attacks blamed on pro-Iranian groups. 

There have been around 20 bomb or rocket attacks against American interests, including bases hosting US soldiers, since US President Joe Biden took office in January.

Dozens of others took place from the autumn of 2019 under the administration of Donald Trump.

There have been calls from pro-Iran groups for the US to exit Iraq, like it is doing in Afghanistan, or face more attacks in order to be forced out. Coalition supply convoys in southern Iraq have faced attacks almost daily.

Last week, the US committed to withdrawing combat forces from Iraq, but didn't set a timeline.
