A convoy carrying food and medicine arrived Wednesday in a besieged rebel-held town close to Damascus, the Red Crescent said, the first aid delivery since world powers agreed on humanitarian access across Syria.

"The convoy has begun to enter Moadimayet al-Sham. There are 35 trucks carrying 8,800 sacks of flour, 4,400 food parcels, high energy foods and medical equipment," the Red Crescent's Muhannad al-Asadi told AFP.
