ROUGH CUT (NO REPORTER NARRATION).
Thousands of Syrians have been stuck in and around Aleppo on Saturday (April 15).
A deal was struck between the government and insurgents to evacuate people from two shi'ite villages in exchange for Sunni rebels and their families, but that has since halted, according to a war monitor and activists.
The British-based Syrian Observatory for Human Rights says the delay was because rebels from Zabadani, one of the towns included in the deal, had not yet been granted safe passage out.
The agreement is one of several concluded in recent months that has seen President Bashar al-Assad's government take back control of areas long besieged by his forces and their allies.
Meanwhile, rebels and their families from Madaya near Damascus sat outside rows of coaches in a bus garage in government-held Aleppo, waiting to move onto Idlib.
