The UN's under secretary general for political affairs has said there is a fresh opportunity for a political, diplomatic approach to the Syria crisis, now that Damascus has acknowledge it has chemical weapons and agreed to join the Chemical Weapons Convention.
In an interview with the BBC's Kim Ghattas, Jeffrey Feltman also suggested that Tehran would have to play a role.
"It's very hard for us to imagine a political solution for Syria that works, that doesn't somehow have Iran as part of the conversation", he said.
