The Syrian government and rebel groups have begun an operation to move people away from four besieged towns, activists say.
People from Foah and Kefraya, two government-held towns in the north-west, have arrived in Rashideen, west of Aleppo, AFP news agency reports.
Similar operations have begun in rebel-held Madaya, near Damascus. It is not clear if nearby Zabadani, included in the deal, is also being evacuated.
More than 30,000 people will be moved.
Last month, the UN described the situation in the four towns as "catastrophic", with more than 64,000 civilians "trapped in a cycle of daily violence and deprivation".
Many people are reported to have died as a result of shortages of food or medicine.
