Syrian President Bashar al-Assad's regime has handed Russia new materials implicating rebels for last month's chemical weapons attack.
After talks in Damascus, Russian Deputy Foreign Minister Sergei Ryabkov said that the corresponding materials were handed to Russia.
He added that Syria told him there was evidence that the rebels are implicated in the chemical attack.
According to Dawn News, he said that Russia would examine the Syrian materials implicating the rebels with the utmost seriousness.
Ryabkov also said Russia was disappointed with the UN report into the chemical weapons attack published this week, saying it was selective and had ignored other episodes, the report said.
Ryabkov is on a visit to Damascus to present the Syrian regime with the results of the agreement between Moscow and Washington reached in Geneva at the weekend to rid Syria of its chemical weapons, it added.
