A new report says the United Nations and partners delivered badly needed medical and food supplies to about 150,000 people in besieged areas of Syria after a cease-fire that started last month led to a drop-off in fighting.

U.N. convoys delivered supplies to people in 10 of 18 areas under siege and to thousands in other, hard-to-reach areas after the Feb. 27 cease-fire, according to the report made available Tuesday.

By comparison, less than 1 percent of areas designated besieged received food aid in all of 2015, according to the U.N. Humanitarian office.

The U.N. estimates that about 487,000 people live in besieged areas and more than 4 million live in hard-to-reach areas.

Peace talks between the Syrian government and opposition delegations are set to resume April 9.
