BEIRUT — Syrian rebels said they have reached an agreement with the government in Damascus on Wednesday to complete their withdrawal from Aleppo, the country’s largest city.

“An agreement has been reached to resume the evacuation of Aleppo,” announced Ahmad Qara Ali, spokesman for the Ahrar al-Sham faction. He said the evacuations would begin “shortly.”

The Syrian opposition agreed to surrender their last foothold in the city, last week, marking the most significant victory for President Bashar Assad since an uprising against his family’s four-decade rule swept the country in 2011.

It followed a punishing offensive by the government and its regional allies that drove out tens of thousands of civilians from the east of the city. It had been held since 2012 by the opposition.
