At least 30 Islamic State of Iraq and the Levant militants were killed on Saturday in the city of Heet, in Iraq's western Anbar province, Iraqi authorities have said.
The US-led coalition air strikes also mistakenly killed five civilians.
The commander responsible for operations in Al-Badiyah, Major General Zia Kazim, told the Anadolu Agency that 30 ISIL militants were killed and 20 injured in Heet city.
The operation was supported by tribal and Shia volunteers, as well as by coalition air strikes.
The commander said that anti-ISIL forces had taken control of five regions in the west of Heet city and one region in the east of Ramadi city, the capital of Al-Anbar province.
The president of Anbar Province Council, Sabah Kerhut, said that five civilians, including one woman and two children, were killed and ten others injured by the air strikes.
He said that coalition planes mistakenly attacked four houses, including the house of Heet city council chairman, Matlub Said.
Iraq has been gripped by a security vacuum since June, when the Islamic State of Iraq and the Levant, or ISIL, stormed the northern province of Mosul and declared what it calls a caliphate in Iraq and Syria.
A US-led international coalition is carrying out air strikes to support Kurdish and central Iraqi government security forces in their fight against ISIL.
