Forty-five civilians have been killed an injured in Iraq after airstrikes by US-led coalition hit Mosul’s Old City early on Sunday.

At least 20 civilians were killed and more than 25 others wounded in an airstrike launched by the international coalition led by the US in north of the Old City, local sources said.

The Old City is home of the ancient Grand Nuri Mosque, where ISIS Leader Abu Bakr al-Baghdadi gave his famous sermon in 2014 declaring the establishment of a so-called caliphate in the region.

“More than 16,000 IS fighters were killed since start of Mosul operations in October,” the Joint Operations Command said previously.

According to Iraqi army, at least 90 percent of territories in western Mosul is under Iraqi government’s control, as the Iraqi forces close in on the terrorists.

Iraqi commanders predicted that the army will retake the city before the end of May.

Since the beginning of Iraqi government’s operation to liberate Mosul from ISIS terrorists, the government has been able to retake the eastern side of the city.

The government also launched another operation in February to liberate the western side of Mosul.

ISIS, which is known as the deadliest terrorist group on earth, emerged in Iraq and Syria in 2014. The terrorist group managed to take a vast area in the two countries, but is losing territories at the moment.
