An unmanned drone bombed a base used by pro-Tehran paramilitary units in central Iraq, the country's military announced Friday, with sources saying one fighter was killed and two Iranians wounded. The US immediately denied involvement in the attack, which took place overnight between Thursday and Friday in an ethnically and religiously mixed area north of Baghdad. It comes as Iraq struggles to keep rising tensions between Iran and the United States - arch-rivals but both allies of Baghdad - from spilling over onto its soil. "The Al-Shuhada base of the Hashed al-Shaabi in the Amerli region was hit at dawn... by an unidentified drone, wounding two people," the Iraqi military said in a statement on Friday. But an official from the Hashed al-Shaabi, a network of Iraqi paramilitary units dominated by pro-Iran Shia forces, and a police officer both gave a toll of one Iraqi fighter dead and two people wounded.
The police source, who visited the site of the attack, said the two wounded were "Iranian military engineers". Pentagon spokesman Sean Robertson said "US forces were not involved" in the attack. Iran says it does not have forces officially deployed in Iraq, but observers say Iranian advisors regularly train Iraqi forces, including the Hashed.
