Who are Turkey's opponents targeting in northern Syria?

For days, the Turkish forces have been bombing the sites of the so-called Syrian Democratic Forces in northeastern Syria.

The Turkish Ministry of Defense announced the neutralization of 14 militants of the Kurdistan Workers' Party and the Kurdish People's Protection Units, while local sources reported to Al-Jazeera that Turkish artillery bombardment targeted sites of what is known as the Syrian Democratic Forces in villages in the vicinity of Ain Al-Arab, on the border with Turkey, in the countryside of Aleppo.

The Turkish artillery, stationed in the opposition areas north of Aleppo, also targeted the positions of the Syrian Democratic Forces in the vicinity of the town of Tal Rifaat in the countryside of Aleppo, according to the same sources.

In a press conference held in Ankara after the government meeting, Turkish President Recep Tayyip Erdogan called for an end to what he called a game that hides extensions of the Kurdistan Workers' Party (PKK) under various names under the guise of war against the Islamic State.

On the other hand, Bayan al-Ali, the co-chair of what is known as the Defense Office of the Autonomous Administration of North and East Syria, called on the two guarantors of the ceasefire, the United States and Russia, to define a clear position on these attacks.

Erdogan's call to stop what he called the game of the PKK and other Kurdish factions raises questions about the party's relations with the Kurdish Democratic Union Party in Syria and its military arm, the Kurdish People's Protection Units, which form the backbone of what is known as the Syrian Democratic Forces.
