Iraqi special forces battled Islamic State militants inside the Mosul University campus on Saturday in a second day of fierce clashes in the complex.
"There are still clashes. We entered the university and cleared the technical institute, dentistry and antiquities departments," Lieutenant General Abdelwahab al-Saadi of the Counter Terrorism Service (CTS) told a Reuters reporter in the complex.
"In the coming hours it will be liberated completely," he said.
CTS troops had gathered in the university canteen. As they unfurled a map of the area, a suspected Islamic State drone flew overhead and they shot at it.
Recapturing the university would be a crucial strategic gain and allow Iraqi forces to advance quicker towards the Tigris river, from where they will be able to launch attacks on the city's west, still all under IS control, military officers say.
