The United Nations says the Syrian government is hampering the delivery of humanitarian aid. Addressing the Security Council, U.N. humanitarian chief Valerie Amos said out of the more than 240,000 people under siege, the United Nations could only reach about 1 percent.

Valerie Amos: “Mr. President, in 2011 I told this council that one million people in Syria needed humanitarian assistance. That figure now stands at 10.8 million, 1.5 million more than there were just six months ago. The number of people in need in hard-to-reach areas now stands at 4.7 million, an increase of 1.2 million since Resolution 2139 was adopted in February.”

Amos said some Syrian opposition groups have also hindered the delivery of aid by attacking or threatening humanitarian workers.
