A major Islamic State group counterattack Friday along the northern edge of Mosul's Old City neighborhood has pushed Iraqi Army forces back some 75 meters (82 yards) and is threatening recent gains in other Old City fronts, an Iraqi military officer said.
The officer said the attack was launched just after noon Friday and estimated it was carried out by 50 to 100 IS fighters. A doctor at a medic station said he received more than a dozen wounded Iraqi soldiers.
Both men spoke on condition of anonymity in line with regulations.
Iraqi security forces have retaken almost all of Mosul — Iraq's second largest city — from IS militants who overran it in 2014.
The counterattacks underscore the extremist group's resilience in Iraq, despite significant territorial losses and months of heavy fighting with Iraqi forces backed by U.S. air power.
The pockets of IS-held Mosul now measure less than a square kilometer.
Also on Friday, The U.N.'s migration agency suspended operations in two camps — the Qayara air strip emergency site and the Haj Ali camp — near Mosul hosting nearly 80,000 displaced Iraqis due to sporadic violence and exchange of gunfire.
