Activists say militants have burned at least five buses assigned to evacuate 2,000 wounded and sick people from two villages in northern Syria.

The incident could scupper 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-Qaida affiliated Fatah al-Sham Front burned buses assigned to evacuate people from the rebel-besieged villages of Foua and Kfarya.

Hezbollah, the Lebanese militant group fighting alongside Syria’s government, says the buses were burned during fighting between the al-Qaida-affiliated Fatah al-Sham Front and a rebel group that supported the evacuations.
