Syria: US welcomes 'milestone' as UN endorses peace plan

A UN plan for Syria is a "milestone" in the efforts to end the conflict there, says US Secretary of State John Kerry.

He said the plan gave Syrians a "real choice... between war and peace".

However, disagreements remain over President Assad and the unanimously agreed Security Council resolution makes no mention of his future role.
