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 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.
