Iraq's military said on Thursday it was resuming operations with the US-led coalition against ISIS which had mostly halted after bases hosting US troops came under rocket attacks and a US drone strike killed a top Iranian commander.
US-Iranian tension threatens to derail the fight against the Sunni extremist group, which seeks a resurgence in northern Iraq three years after its military defeat at the hands of the coalition, Iraqi forces and Iran-backed Shi'ite Muslim militias.
That tension boiled over when the United States killed Iranian military mastermind Qassem Soleimani in a drone strike in Baghdad on Jan. 3.
