In Iraq, the U.S.-backed Iraqi forces and government militias are continuing the campaign to retake the city of Mosul from ISIS. The Iraqi military says it discovered a mass grave with as many as 100 decapitated bodies during its advance into the town of Hamam al-Alil to the south of Mosul. This comes as residents of al-Qayyarah, a town about 40 miles south of Mosul, report being sickened by the poisonous smoke from continuously burning oil well fires. The Iraqi military says ISIS militants lit the oil wells on fire in August while retreating from the town. The fires continue to burn three months later.
