Two teenage girls have described the horror of the moment a drone struck their school in Syria, killing four friends.
Renda Bakr, 17, and Novin Ezzat, 18 heard the buzz of the unmanned craft but, after that, it was all a blur of screams and blood as a Turkish drone appears to have slaughtered four innocent Kurdish students in its ongoing strikes on Kurdish areas of Syria.
The two girls are students at a United Nations (UN)-backed boarding school in the village of Szamuka, 16 km west of the city of Al-Hasakah where they live and study.
