Reports say the last ISIS-held quarter, known as the Old City, was hit by air strikes and artillery salvos, as local commanders prepare to move in and retake full control.
However, they are facing more suicide attacks, including several from female bombers, as the battle for Mosul enters its final phase.
You will recall that the Iraqi forces launched a major offensive against ISIS in Mosul in October 2016, with Kurdish Peshmerga fighters, Sunni Arab tribesmen and Shia militiamen providing assistance.
The pro-government troops also enjoy the support of US-led coalition warplanes and military advisers.
