Syria's warring parties are beginning formal peace talks in Geneva for the first time since the conflict began three years ago, but they will not be face-to-face.
The government and rebel delegations will sit in separate rooms, and conduct negotiations through the UN mediator.
Diplomats have said a main concern will be ensuring neither side walks out.
Syrian presidential adviser Dr Bouthaina Shaaban told the BBC's Lina Sinjab that the Syrian government's priority is to ''stop terrorism''.
