UN mediator Lakhdar Brahimi has said he does not expect to achieve "anything substantive" in the first round of Syria talks before they end on Friday. He said he was "not disappointed" and that "the ice is breaking slowly".
He also said that the UN and Syrian government were still negotiating on access for a humanitarian aid convoy into the besieged city of Homs. The idea of a transition process has proved to be a major sticking point at the peace talks in Geneva.
Mr Brahimi told reporters that the gap between the two sides remained "quite large" but there was a willingness to continue the talks. He voiced hope that Russia and the US would exert greater influence over the two sides to help bridge that gap.
