Turkey wants to play a bigger role in the Iraqi-led offensive against the militants in Mosul, but Iraq's Prime Minister Haider al-Abadi on Saturday declined an offer from Ankara to take part.
Speaking at a joint news conference with his visiting French counterpart, Cavusoglu also said Turkey will be more active in fighting the Kurdish PKK militant group in Iraq.
The PKK has waged a three-decade insurgency in southeastern Turkey and maintains bases in northern Iraq.
