MOSUL, Iraq (AP) — Sporadic clashes are continuing in Mosul, even after Iraq declared a “total victory” over the Islamic State group in the city.

At least one airstrike hit the Old City, the scene of fierce final battles with IS, sending a plume of smoke into the air on Tuesday.

Meanwhile, Amnesty International released a report saying that the conflict in Mosul has created a “civilian catastrophe,” with the extremists carrying out forced displacement, summary killings and the use of human shields

Iraq’s Prime Minister Haider al-Abadi declared the “total victory” in Mosul on Monday evening — after a nearly nine-month-long battle with IS fighters.

The fight dealt a huge blow to IS’ so-called territorial caliphate, but also killed thousands, left entire neighborhoods in ruins and displaced nearly 900,000 from their homes.
