US might be walking out from UN meetings on Syria peace process amid backlash

The United States' special representative for Syria has cancelled his planned meetings at the United Nations on Thursday to discuss the Syria peace process, U.S. officials said.

It was not clear who Jim Jeffrey had been scheduled to meet. The U.N.'s envoy to Syria, Staffan de Mistura, was set to brief the U.N. Security Council on Syria's peace process later on Thursday.
