14 January 2014 Last updated at 07:52 GMT
Britain and the US have warned they will rethink support for Syria's main opposition group if it fails to join peace talks, a Syrian source has said.
The official from the Syrian National Coalition told reporters that the UK and the US were adamant the group must go to Geneva for next week's talks.
The coalition will hold a vote on Friday on whether or not to attend.
