BAGHDAD - Unknown drones bombed a base housing headquarters of Hashd Shaabi Forces in Iraq's central province of Babil early Saturday, killing one person and injuring seven others, an Interior Ministry source told Xinhua.

The drones targeted the vast military site, known as Camp Kalsu, which houses bases of the Iraqi army, federal police, and Hashd Shaabi forces in the Mahawil area, in the northern part of Babil province, the source said.

The airstrikes killed a Hashd Shaabi fighter and injured five fighters and two Iraqi soldiers, in addition to causing a huge fire in the attacked targets, the source said, citing initial reports

The death toll could rise as ambulances were still rushing the injured to hospitals, while rescue teams and fire trucks were working to put out fires.

No statement has yet been issued by the Iraqi government regarding the airstrikes, but the Hashd Shaabi Forces said in a brief statement that an investigation team had arrived at the scene, and more details would be revealed later.
