"Nine lorries are currently being unloaded in Daraya. They are carrying food aid, including dry goods and flour, non-food aid as well as medical aid," said Tamam Mehrez, operations director of the Syrian Red Crescent.
The aid delivered yesterday would be sufficient for one month, Mehrez added, without specifying how many people would benefit.
Earlier yesterday, the UN said Syria had given approval for humanitarian convoys to reach all of the country's 19 besieged areas, including Daraya, by the end of the month.
He made the comments after the weekly meeting of the Syria humanitarian taskforce, co-chaired by the United States and Russia, which has for months been trying to boost aid supplies to millions of Syrians in need.
That taskforce has faced pressure, including from France and Britain, to start air-dropping aid into besieged areas, with Syrian President Bashar al-Assad's military continuing to block road convoys.
De Mistura said the pressure placed on Damascus by the prospect of air drops had led to the road convoy approvals and voiced hope that a surge of aid deliveries in the coming weeks would make dangerous and costly air drops unnecessary.
