Operations in the region are still ongoing, the ministry statement added.
Turkey regularly carries out operations in Iraq, which lies on its southern border, as part of its offensive against Kurdistan Workers’ Party (PKK) members based in the Kurdish region of northern Iraq.
The PKK launched an armed rebellion against the Turkish state in 1984, first seeking independence and more recently, autonomy. More than 40,000 people have been killed in the conflict.
Turkey launched Operation Claw-Lock in April to target the PKK’s hideouts in northern Iraq.
The PKK is regarded as a “terrorist” group by Turkey, the United States and the European Union.
Ankara’s military operations in northern Iraq have been criticised by the Iraqi government, which has accused Turkey of failing to respect Iraq’s territorial integrity.
The Iraqi authorities said that Turkey had “blatantly violated” Iraq’s sovereignty and summoned Ankara’s ambassador to Baghdad after an attack on a resort in northern Iraq’s Duhok province in July was blamed on Turkey.
The attack left eight people dead.
Turkey denied responsibility, and said that the attack had been carried out by “terrorists”.
