The Kurdish-backed Syrian Democratic Council (SDC) is holding talks with Syrian government officials in Damascus this week, accompanied by representatives of the US-backed Syrian Democratic Forces militia, SDC co-chair Riad Darar said.
It marks the first declared SDC visit to Damascus.
The delegation is led by top Syrian Kurdish official Ilham Ahmed, added Darar, speaking by phone from Vienna on Friday.
Darar said the talks were initially expected to focus on matters of service provision, but added: "I believe matters will develop to what is wider than that."
"There could be some political and some security meetings," he said.
