The army has opened three "corridors" for people to flee from newly-recaptured territory into government zones.

Once the government had whittled down rebel territory to three isolated pockets, it pursued separate negotiations with the factions in each zone.

The first deal brokered by Russia was reached with the hard line Islamist group Ahrar al-Sham for the town of Harasta and saw more than 4,500 people, including over 1,400 fighters, evacuated to Idlib.

The second agreement was reached with Faylaq al-Rahman on Friday and provides for evacuations, medical treatment for wounded civilians and fighters, and the release of detainees held by the rebel group.

Syrian state TV on Saturday interviewed eight men who said they had been detained by Faylaq and were released under the settlement.

Sabah al-Salloum desperately hoped her son Munzer, kidnapped four years ago by Ghouta rebels, would be among them.

"I heard from the news the kidnapped would be released, and I'm losing my nerves waiting. I couldn't sleep," Salloum said.

With the conflict grinding on into its eighth year, Syria's government is more determined than ever to clear opposition holdouts around the capital to halt rebel rocket fire onto Damascus.
