The explosion occurred at a joint checkpoint between the civilian police and the Sultan Murad faction at the entrance to the Kurdish city, the watchdog group said.

It added that death toll is expected to rise further as 12 injured.

In October 2019, Turkish army in coordination with its allied Syrian rebels occupied Sari Kani and Gri Spi north of Hasaka governorate in Operation Peace Spring from the Kurdish-backed Syrian Democratic Forces (SDF). Since then, residents in the area have experienced security chaos, blasts, infighting, looting, rape and other human rights abuses.
