The base, situated north of the capital Baghdad, has repeatedly come under rocket attacks. In February, a similar incident injured two people.
Five rockets have targeted Iraq’s Balad Air Base, the country’s security officials said on Sunday. According to the officials, the Katyusha rockets landed in an area hosting US contractors. However, there were no reports of any casualties in the attack and no group has claimed responsibility for it.
Earlier this month, two rockets landed near the base without causing any casualties.
In late February, two employees of the base suffered injuries after three missiles hit the facility.
