Granting relief groups access to an estimated 250,000 people trapped by fighting across Syria was one of the goals of the peace talks held last week in Switzerland, which recessed on Friday with no substantial results.
Despite lengthy discussions, the sides could not agree on passage for an aid convoy to reach 2,500 people trapped in the old city of Homs, Syria's third-largest city, with no access to food or medicine.
Anwar Raja, a spokesman for the Popular Front for the Liberation of Palestine-General Command (PFLP-GC), which operates in Yarmouk, said the group had coordinated with the Syrian Arab Red Crescent on Friday and Saturday to extract "hundreds" of the suburb's residents.
