The Balad military base was a target of last week's rocket attacks carried out in retaliation for the death of Iranian Quds chief Qasem Soleimani. The attack resulted in no casualties or damage.
Seven mortar bombs have hit the Iraqi Balad Air Base in the north of the country, Reuters quoted military sources as saying. According to sources, four Iraqi soldiers were injured in the incident.
However, AFP cited security forces as saying that the base was hit by just four rockets.
