More than 200,000 people have fled fighting in west Mosul since the operation to retake the area from extremists was launched last month, Iraq's ministry of migration and displaced said Saturday.
The battle for west Mosul -- the most populated urban area still held by ISIS -- was launched on Feb. 19, and Iraqi forces have since recaptured a series of neighborhoods from the extremists.
"The number of displaced from the areas of the right bank (west side) of the city of Mosul has risen to 201,275 people," the ministry said in a statement.
ISIS overran large areas north and west of Baghdad in 2014, but Iraqi forces backed by U.S.-led airstrikes have since retaken most of the territory they lost.
Iraqi forces launched the operation to recapture Mosul in October, retaking the east of the city before setting their sights on the smaller but more densely populated west.
The United Nations said Thursday that there were some 600,000 people still in west Mosul, 400,000 of whom are "trapped" in the Old City area under siege-like conditions
