The Wall Street Journal reports: The U.S. expects up to 700,000 people to be displaced in the fight to drive Islamic State from Mosul and has positioned stocks of food and supplies on the outskirts of Iraq’s second-largest city, senior administration officials said Monday.

Underscoring concerns about humanitarian fallout from the battle, Iraqi troops discovered what could be a mass grave some 30 miles southeast of Mosul, according to Iraqi Lt. Gen. Abdulamir Yarallah, commander of the Nineveh liberation operation, where he said 100 decapitated bodies were found at an agriculture school in the town of Hamam al-Alil.

He provided few details but said Iraqi officials will be sending specialized teams to investigate. Mosul is located in Nineveh Province.

Displaced people continued to flow Monday to camps miles away from the front lines of Mosul, with approximately 33,000 fleeing the city since the campaign began about three weeks ago, according to Iraqi and U.S. government tallies.
