United Nations, Rabi'II 18, 1437, January 28, 2016, SPA -- A UN senior official denounced the obstacles set by the regime of Bashar Assad in Syria for delivery of the humanitarian aid, describing it as unacceptable. UN Under-Secretary-General for Humanitarian Affairs Stephen O’Brien said that the Syrian regime in 2015 ignored most United Nations requests to deliver humanitarian aid to some of the 4.6 million people in hard-to-reach and besieged areas and only 620,000 received help. Stephen O'Brien told the U.N. Security Council on Wednesday that last year the United Nations made 113 requests to the Syrian government for approval of inter-agency aid convoys, but 75 percent of the requests went unanswered. "Such inaction is simply unacceptable," he said. "The impact on the ground is tangible: in 2013, we reached some 2.9 million people through the inter-agency convoy mechanism, but only 620,000 (in 2015)." --SPA 03:23 LOCAL TIME 00:23 GMT www.spa.gov.sa/w
