Hospital director Ahmed Shami says the fighting took place early today on the northern outskirts of the city of Fallujah, which has been in the hands of the Islamic State group since early January.
Shami says at least 10 militants and a woman were also killed. He had no details about the clashes beyond saying that the bodies of the victims were brought to his hospital.
Along with Fallujah -- which is 65 kilometres west of Baghdad -- the Islamic State controls large swaths of the country's north and west.
