UN: Only 30% of aid reaches Syrians in besieged areas

Desperately-needed aid has reached only 30% of Syrians living in besieged areas, with the total dropping to less than 10% in hard-to-reach areas this year, the UN's humanitarian chief has said.

Stephen O'Brien told the US Security Council that many of the 4.6 million Syrians in need in these areas cannot be reached because of insecurity and obstruction by combatants - even with a cease-fire in place.
