Syria peace envoy Lakhdar Brahimi was in talks with top diplomats from Russia and the United States in Geneva on Friday, in a bid to help bridge their differences over the conflict-torn country, dpa reported.
The US wants Syrian President Bashar al-Assad to step down, while Russia says it is a matter for Syrians to decide.
The meeting between the veteran Algerian diplomat, Russian Deputy Foreign Minister Mikhail Bogdanov and his US Deputy Secretary of State William Burns is their second since December 9.
Earlier this week Brahimi he did not see al-Assad as part of the transitional government that was outlined in a plan agreed to by major powers and Arab countries in Geneva last year.
"We are heading to Geneva meeting with Burns and Brahimi to discuss all files, looking forward to a real implementation of the Geneva statement without impinging on the Syria's sovereignty and territorial integrity or interfering in its people's right to choose their leadership," Bogdanov told Russia Today TV.
US State Department spokeswoman Victoria Nuland said Thursday the aim of the meeting would be how to implement such a transition in concrete terms.
More than 60,000 people have been killed in Syria since the conflict started in March 2011, according to UN estimates.
