The last vestiges of what just a few years ago was proclaimed as the Islamic State’s new ‘caliphate’ is crumbling under constant attack from Iraq’s forces as they push to retake Mosul.

Iraqi military spokesmen say that the ISIS fighters remaining in what is left of their stronghold of Mosul are in a “fight to the death.” Only about 5 percent of the city remains in the hands of the Islamic State as US-backed Iraqi forces continue to keep the pressure on.

Gen. Abdel Ghani al-Asadi, the head of Iraq’s special forces, said his troops were just 250 yards from the Tigris River on Tuesday after retaking the Mosul’s main hospital compound from ISIS the day before.

He said the militants are increasingly resorting to suicide bombings, and he expects the fighting to get even heavier as they are pushed closer to the river.
