The desperate residents of a besieged district of Damascus were expected to run out of food on Sunday, leaving 18,000 people facing starvation and leading relief agencies to declare the crisis "unprecedented in living memory."

Food packages had not been delivered to the Yarmouk Palestinian refugee camp for 10 days, and Syrian authorities were not expected to allow food trucks in over the Easter weekend.

Residents have resorted to eating leaves and animal feed. Some say they cannot get access even to scraps, as a desperate blockade by government forces, in place for nearly 18 months, continues to cut off supplies.
