As many as 170 Daesh fighters have been killed during military operations conducted by the Kurdish forces backed by US-led air strikes in northeastern Syria, The Syrian Observatory for Human Rights (SOHR) said Wednesday.

They were killed in coalition bombings and in attacks of the Kurdish forces in al-Hasakah.

The attacks occurred on the outskirts of the town of Tel Tamr where Daesh fighters have been clashing with Syrian Kurdish militias and their allies since February.
