An aid convoy headed for Daraya, a Syrian town that has been under siege by government forces since November 2012, was forced to turn back after it was refused entry at the last government checkpoint, the United Nations and its international partners say.
"We were hoping that today's delivery of life saving assistance would have been a first step and lead to more aid being allowed in," says Yacoub El Hillo, UN resident and humanitarian coordinator in Syria.
The convoy was supposed to provide essential medical supplies, including vaccinations for children under the age of 12 and food for children.
Stephane Dujarric, a UN spokesman, says that the UN and its aid partners "decided to abort the mission" because the nutrition items for children had been removed at the checkpoint. He calls the situation "extremely disappointing."
