Air strikes killed at least 23 civilians including 10 children in a village held by the Islamic State group in northeastern Syria Tuesday, the Syrian Observatory for Human Rights monitor said.
"We don't know for the moment if the US-led international coalition or Iraqi forces carried out the strike" on the village of Al-Qasr in the northeastern province of Hasakeh, the Britain-based monitor said.
Fire and explosions are seen in what purported to be the Mountain 47 region, countryside south of Hama city, Syria, on Sunday.
