In Iraq, a medical aid group said Wednesday tens of thousands of civilians are fleeing fighting in western Mosul and are in urgent need of medical care. Doctors Without Borders, or MSF, described ambulance teams unable to cope with the number of trauma victims caught in the crossfire of a U.S.-backed assault on the city, which is partially controlled by ISIS. MSF said some children arriving in camps for the displaced arrived with acute symptoms of malnutrition.
