Turkey says its warplanes have destroyed at least 18 targets reportedly belonging to the outlawed Kurdistan Workers' Party (PKK) militant group in northern Iraq.
The operation took place during the weekend, Turkey's official Anadolu news agency reported on Sunday.
It hit the Hakurk, Zap, Metina, Gara, and Avasin-Basyan regions of northern Iraq.
The militants have been fighting a decades-long war against Ankara in quest for an independent state in southeastern Turkey, in which around 40,000 people have been killed.
Since January, Turkey has also been waging a concerted operation against Kurdish militants known as People's Protection Units (YPG) in northern Syria. The Turkish administration says the YPG is associated with the PKK.
The Syria attacks have, however, forgone Damascus' approval. They have also pit Turkey against the United States which supports the militants.
On Saturday, Turkish President Recep Tayyip Erdogan said 3,171 YPG militants had been “neutralized” since the beginning of the operation, meaning they had either surrendered or been killed or captured.
He also said Turkish troops had managed to encircle Afrin, which has been the focus of the operation and that they could enter the town any moment now.
