UNITED NATIONS - UN-Arab League mediator Kofi Annan is urging Syria's government to accept UN conditions for expanding the distribution of humanitarian aid to roughly 1 million Syrians in need of assistance, the United Nations said on Tuesday.The aid is necessary because of the desperate situation many Syrians find themselves in after 14 months of a Syrian government assault on an opposition that is increasingly determined to oust President Bashar Assad."The joint special envoy (Annan) remains extremely concerned about the plight of 1 million Syrians in need of humanitarian assistance," UN spokesman Martin Nesirky told reporters."He strongly urges the government to accept the conditions for a scaling up of the humanitarian assistance without further delay," he said."He underlines the need for a speedy agreement consistent with the government's commitment to allowing unimpeded access to and provision of assistance to Syrians in need," Nesirky said.
