At least two rockets have targeted Camp Victory, which houses American forces at Baghdad International Airport, an Iraqi security source said on Sunday.
US forces and assets stationed in Iraq often come under attack, with the most frequent target being the US embassy in the Green Zone, an area of central Baghdad that is the site of numerous government and diplomatic buildings.
According to social media reports, a possible attack had been expected against the US assets in Baghdad and local security forces have been patrolling major locations hosting US troops.
The attack reportedly resulted in no casualties.
The latest attack comes after on April 22, multiple rockers hit Camp Victory, also resulting in no injuries.
