UN talks with Syria on chemical arms probe at 'impasse'

UNITED NATIONS - Discussions between the United Nations and Syrian President Bashar Assad's government on a possible investigation into the alleged use of chemical weapons in Syria have reached an impasse, UN diplomats said on Wednesday.
Syria and the United Nations have been exchanging letters for weeks but the two sides are far from agreement on how the investigation should be run, diplomats said on condition of anonymity.
Syria has asked the United Nations only to investigate what it says was a rebel chemical attack near Aleppo last month. The opposition has blamed President Bashar Assad's forces for that strike and also wants the UN team to look into other alleged chemical attacks by the government.
