BEIRUT — Syrian rebels say an agreement has been reached with Russia for a cease-fire in Aleppo to evacuate remaining civilians and rebels from besieged districts.

Osama Abu Zayd, a legal adviser for an umbrella group of rebel factions known as the Free Syrian Army, says the cease-fire went into effect Tuesday evening.

He says the first batch will begin evacuating later Tuesday.

Yasser al-Youssef, a spokesman for the Nour el-Din el-Zinki rebel group, confirmed the cease-fire and says the goal is to evacuate civilians and rebels from besieged areas.

There was no immediate comment from the Syrian government or Russia on the reports.
