Turkey says it is determined to secure its southern border.
Tensions have increased along Turkey’s border with northern Syria.
Turkey’s defence ministry says its forces have hit nearly 500 targets in Kurdish-held areas since Sunday.
Turkey is also reporting casualties among fighters from the SDF – the Syrian Democratic Forces.
Turkey’s attacks follow a bombing in Istanbul on November 13, for which the government blames the outlawed Kurdish group, the PKK.
Ankara says it is aiming at bases in Syria belonging to the YPG, a Kurdish group with links to the PKK.
Since 2016, Turkish forces have conducted three ground operations to clear out YPG fighters from northern Syria.
Now, President Recep Tayyip Erdogan is promising to launch another military operation.
