Convoys of evacuees traveled from a rebel-held area of Aleppo and from two Shiite villages besieged by insurgents on Monday after a days-long stand-off.
Dozens of buses carrying thousands of people from Aleppo's tiny rebel zone reached insurgent areas of countryside to the west of the city, according to a United Nations official and the Syrian Observatory for Human Rights, a monitoring group.
At the same time, 10 buses left the Shiite Muslim villages of al-Foua and Kefraya, north of Idlib, for government lines in Aleppo, the sources said.
