Activists say fighters have burned at least five buses assigned to evacuate wounded and sick people from two villages in northern Syria.
The incident could scuttle a wider deal that encompasses the evacuation of thousands of trapped rebel fighters and civilians from the last opposition foothold in east Aleppo.
The opposition’s Britain-based Syrian Observatory for Human Rights said Sunday that the al-Qaeda affiliated Fatah al-Sham Front burned buses assigned to evacuate people from the rebel-besieged villages of Foua and Kfarya.
Hezbollah, the Lebanese terror group fighting alongside Syria’s government, says the buses were burned during fighting between Fatah al-Sham Front and a rebel group that supported the evacuations.
The Observatory says six buses were burned while Hezbollah’s media outlet puts the number at five.
