Iraq's security and paramilitary forces began Sunday a military operation along the border with Syria aimed at clearing the area of Islamic State group militants, the military said in a statement.
The military said the operation that began at sunrise was being carried out by Iraqi troops and members of the Popular Mobilization Forces that largely consist of Iran-backed militias.
It said the operation will last several days and was the first phase of the Will of Victory Operation securing the western province of Anbar and the central and northern regions of Salahuddin and Nineveh.
"We press on the hands of our heroic forces that will achieve victory with the will of its heroes against the gangs of Daesh," said Iraqi Prime Minister Adel Abdul-Mahdi using an Arabic acronym to refer to ISIS. "May God protect you and make you victorious."
ISIS once held large parts of Syria and Iraq where it declared a caliphate in 2014. The extremists lost in March the last territory they controlled in Syria.
