Iraqi special forces swept through the campus of Mosul University on Sunday to clear it of any remaining Islamic State group militants after taking full control of the area, a spokesman said.
A military statement said troops had also taken another area along the eastern bank of the Tigris river, in gains that are bringing more of Islamic State group's last major stronghold in the country under Iraqi forces' control.
Counter-terrorism service troops drove the militants back inside the strategically located university complex and seized clusters of buildings including colleges on Saturday.
"The university is completely liberated and forces are sweeping the complex for any hiding militants," counter-terrorism service spokesman Sabah Numan told Reuters by phone on Sunday.
Parts of the sprawling campus overlook neighboring districts in eastern Mosul and towards the river. Taking the entire east bank of the Tigris, which bisects Mosul from north to south, will allow Iraqi forces to begin assaults on the city's west, which Islamic State still holds.
Loss of Mosul could spell the end of the Iraqi side of the Islamic State group's self-styled caliphate, which it declared from the city after sweeping through vast areas of Iraq and Syria.
