Syrian opposition groups are set to resume talks in Qatar to try to form a united body in the fight against President Bashar al-Assad, the Voice of Russia reported.
Delegates were quoted as saying that main points had already been agreed.
The fractious opposition has been under pressure from the US and other backers in the region to clinch a deal.
However, the Syrian National Council - which is based outside the country - is concerned it may be sidelined by the new opposition body.
The proposed unified group, tentatively called the Syrian National Initiative, is intended to merge disparate military and political groups to form a credible alternative to Mr Assad's government.
