BAGHDAD - Coalition air strikes killed around 25 Islamic State fighters on Wednesday near the northern Iraqi city of Baiji, residents told Reuters.
They said a series of bombings beginning in the early hours hit the town of al-Siniya, west of Baiji, a stategic city adjacent to the country's largest refinery, part of a multinational effort to check the group's progress.
Iraqi army tanks and armoured vehicles on Wednesday also fought off an advance by Islamic State militants on the town of Amiriya Fallujah, west of the Iraqi capital Baghdad, army sources said.
The sources added that around 400 fighters amassed in the nearby towns of Fallujah and Karma the day before, piling pressure on the capital's western flank.
Government forces fought back Islamic State outside Amiriya Fallujah - which faced a siege by the militants for much of this month and is the last government-controlled town before the key provincial city of Fallujah.
Soldiers destroyed five of the fighters' vehicles, a security source said.
