UNITED NATIONS - The United Nations and Syria have not yet agreed on how much access a team of chemical weapons inspectors will have to investigate allegations that such arms were used recently in the Syrian conflict, according to a letter to Syria's UN envoy.
The United Nations said last month it would investigate the Syrian government's allegations that rebels used chemical arms in an attack near the northern city of Aleppo.
Western countries also want a probe of two additional rebel claims about the use of such arms. The opposition says Syrian President Bashar Assad's government carried out all three alleged chemical attacks.
"There's no agreement on access yet," a UN Security Council diplomat told Reuters on condition of anonymity. "The inspectors won't be deploying until there's agreement on access and other modalities."
