Talks aimed at ending a 40-year-old militant conflict have fostered peace hopes in Turkey but the precarious situation of Kurdish forces in Syria and uncertainty about Ankara's intentions have left many Kurds anxious about the path ahead.

A key dam in northern Syria has become a flash point in the conflict between Kurdish forces and Turkish-backed armed groups.

Battles between Turkish-backed groups, supported by air strikes, and Kurdish-led forces killed 37 people on Thursday in Syria's northern Manbij region, a war monitor said.

Turkish Foreign Minister Hakan Fidan said on Friday that the new Syrian administration should be given an opportunity to address the presence of Kurdish militants in the country, and reiterated that the Turkish military would act if it did not.

Since the ousting of former Syrian president Bashar al-Assad last month by rebels, some of whom Turkey supported, Ankara has demanded that the YPG disband, its non-Syrian militants and foreign terrorist fighters leave Syria, or be repatriated to their source countries, and its leaders turn themselves in.

Turkey threatened Tuesday to launch a military operation against Kurdish forces in Syria unless they accepted Ankara's conditions for a "bloodless" transition after the fall of strongman president Bashar al-Assad.

Turkish-backed forces are intensifying attacks on Kurdish-controlled areas, targeting civilians and critical infrastructure as fears grow over a potential dam collapse.

The Syrian Observatory for Human Rights (SOHR) reported on Sunday that 85 Turkey-backed fighters and 16 fighters from the Kurdish-led Syrian Democratic Forces (SDF) were killed in the fighting, which began on Friday evening in several villages near the city of Manbij.

The Turkish Armed Forces have been put on high combat readiness due to the possibility of conducting an operation against Kurdish armed groups in Syria. This information was relayed to the pro-government newspaper "Türkiye" by sources from the Turkish Ministry of Defense.
