The United Nations World Food Programme (WFP) said the Syrian regime has prevented supplies from entering eastern Ghouta meaning that some 200,000 civilians who stayed after the regime retook it from rebels went without much needed humanitarian support.
"Eastern Ghouta is no longer under siege, but we still have not received passes to enter the region" Jakob Kern, WFP Syria Country Director said at a press conference at the UN Office in Geneva.
He called on the Syrian regime to allow the WFP teams to enter the area to deliver urgent aid to the population.

The UN official warned of a great disaster if the city of Idlib, which hosts millions of displaced people from various parts of the country, is attacked.
He stressed on the need to start the peace process in Syria as soon as possible and said "the Syrian people are fed up with the war that has been going on for seven years. The Syrians want to return to peace and to their normal lives".
The people of Eastern Ghouta were evacuated on 22 March.
