Iraqi’s Prime Minister Haider al-Abadi has said that the Iraqi security forces’ mission to recapture the Mosul city from Daesh insurgents was in its final stages, Reuters reported on Wednesday.

The Iraqi Prime Minister told a news conference on Tuesday night that he warned the insurgents that they must surrender or be killed.

According to the report, Iraqi forces have launched military offensive on October and the forces have driven Daesh insurgents from eastern Mosul and are now making advances in the western sector.

The city on the Tigris River is the last urban stronghold in Iraq of the insurgents, who declared a caliphate in parts of Iraq and Syria after they captured it in 2014.

"The battle now is in the final stages. Daesh become day after day surrounded inside a tight area and they are in their final days," Abadi said as quoted by Reuters.

He also pledged to treat the families of Daesh fighters fairly.

"Let me be very clear, we will preserve families of Daesh who are civilians but we will punish the terrorists and bring them to justice if they surrender," he added.

The Iraqi Prime Minister said he would visit Washington next week and would meet the United States President Donald Trump to discuss the war.
