Kurdish forces backed by U.S.-led coalition airstrikes drove Islamic State militants out of 10 villages in Iraq's Kirkuk province on Wednesday in an offensive to secure their territory to the north, Kurdish military sources said.
The assault began at dawn in the Daquq area, around 175 kilometres (110 miles) north of the Iraqi capital Baghdad. By evening, Kurdish forces had taken an area of around 250 square kilometres, the sources said.
An aide to a top Kurdish commander taking part in the offensive said five peshmerga had been killed, most of them by improvised explosive devices.
The frontline between Kurdish peshmerga forces and Islamic State in northern Iraq has hardly budged for months.
The Kurds already control most of the territory they claim as their own, and have little incentive to push further into predominantly Sunni Muslim Arab towns and villages, except where they pose a direct threat to their region.
"This area (near Daquq) posed a danger to the main road from Kirkuk to Baghdad and the Kurdish and other villages adjacent to the areas occupied by Daesh," Brigadier General Aras Abdel Rahman said, using an Arabic acronym for Islamic State.
The peshmerga have emerged as an important ally for the United States in its aerial campaign against Islamic State. Together they have pushed back the Sunni insurgents in northern Iraq, and the peshmerga has thus expanded the territory of its autonomous region.
Last summer, the Kurds took full control of the disputed city of Kirkuk after the Iraqi army abandoned its bases there, but western parts of the province such as Hawija remain under Islamic State control.
The Kurds have since carried out several offensives aimed at creating a buffer around the oil-rich city, which they say they will never relinquish.
