Iraqi Kurdish peshmerga forces repelled a multi-pronged offensive by ISIS in the northern province of Nineveh on Wednesday, officials said.
One of the targeted areas included a base housing Turkish soldiers that has been at the heart of a bitter dispute between Baghdad and Ankara.
Peshmerga forces repelled coordinated attacks by IS in Nawaran, Bashiqa, Tal Aswad, Khazr and Zardik, the Kurdistan Regional Security Council (KRSC) said.
"This was an attempt by [ISIS] to breach peshmerga defensive lines following significant losses in recent months," it said.
"A number of fronts, including Bashiqa and Nawaran and Khazr north and east of Mosul, were attacked by [ISIS] terrorists this evening," Jabbar Yawar, the secretary general of the ministry responsible for the peshmerga forces, told AFP.
The jihadists "used car bombs and mortars and rockets and after that launched attacks on peshmerga sites on all of these fronts", Yawar said.
The KRSC, which is headed by de facto regional president Massud Barzani's son Masrour, claimed that more than 70 ISIS members were killed in the attacks.
That claim could not be independently verified, and the statement provided no indication of possible peshmerga casualties.
