Rockets hit Iraqi base hosting US contractors, one Iraqi injured, security officials say

No group immediately claimed the attack. It was the second salvo of rockets to hit a base hosting US forces or contractors in less than a week.

The Iraqi military said four rockets hit the base. Iraqi security officials initially said three rockets had hit and told Reuters the contractor had suffered non-lethal injuries.

The officials spoke on condition of anonymity because they are not authorised to speak to the media.

Armed groups that some Iraqi officials say are backed by Iran have claimed similar incidents in the past, including an attack last week on the Erbil International Airport compound. The attack killed a contractor working with US forces at the military base part of the compound.

Iran-aligned paramilitary groups demand that all foreign troops, including US forces who number around 2,500 in Iraq, leave the country, calling their presence an occupation.

A US-led coalition whose mission is to fight Islamic State militants is still stationed in Iraq, as well as a NATO-led mission that trains Iraqi security forces.
