ERBIL, Iraq: In a push at dawn, Iraqi forces launched an operation on Thursday to retake the town of Hawija - one of the last extremist strongholds in Iraq - from Daesh (ISIS), according to a statement from the Iraqi prime minister's office.

The operation began just two days after Iraqi forces began an offensive against Daesh holdouts in Iraq's vast western Anbar province, said Prime Minister Haider al-Abadi.

Hawija, 240 kilometers north of Baghdad, is one of the last pockets of territory held by the extremist group in the country. Daesh has been steadily losing ground and seeing its sprawling caliphate that in 2014 spanned a third of the territory of Iraq and also neighboring Syria crumbling fast.

Earlier this month, Iraqi and U.S.-led coalition planes stepped up a campaign of airstrikes on Hawija, targeting Daesh bases and weapons facilities.

Daesh "now faces the mighty (Iraqi security forces in) the last two areas where they hold any territory in Iraq," U.S.-led coalition spokesman Col. Ryan Dillon said Thursday morning in a statement posted on Twitter.

In the western Anbar province, Iraqi forces retook the town of Rihana on Wednesday, according to a statement from the coalition. The territory Daesh holds in the western province lies mainly along the border with Syria in the Euphrates River valley.

Iraqi forces declared victory over the extremists in Mosul in July and in the western town of Tal Afar the following month.

Plans to retake Hawija have been complicated by political wrangling among the Iraqi security forces, Shiite armed groups and the Kurdish Peshmerga troops. The town is part of the Kirkuk governorate, which is disputed between the central government in Baghdad and the northern Iraqi Kurdish autonomous region, where a referendum on independence is scheduled to take place next week.

Tensions have risen in the area recently as Kurdish leaders are pressing ahead with the referendum, a move dismissed by the central government as illegal and destabilizing to the country.

Iraqi Lt. Gen. Abdul Amir Rashid Yarallah, deputy commander of the joint operations, told The Associated Press that along with the push to liberate Hawija, Iraqi forces and Shiite militias are also fighting to liberate the nearby town of Sherqat.

Lt. Gen. Raid Shawkat Jawdat, commander of the Iraqi Federal Police that is also taking part in the operation, said dozens of their armored vehicles started the push at dawn Thursday.
