Activists and residents say thousands of Syrians evacuated from their besieged towns have spent the night on buses at an exchange point as a much criticized population transfer deal stalls.

Ahmed Afandar, a resident evacuated from his hometown near Madaya, says dozens of buses carrying children, women and men are not allowed to proceed toward rebel-held Idlib as planned. He said it is not clear what hinders the completion of the evacuation.

Rami Abdurrahman, head of the Britain-based Syrian Observatory for Human Rights, says the Syrian government and rebels who negotiated the deal have differed over the evacuation of gunmen from the towns.

A resident of Zabadani, another rebel-held town to be evacuated, Amer Burhan says no evacuation has taken place from there.
