The materials were found as Syrian opposition forces have recently kicked off a blame game to charge Syrian army for the use of chemical weapons against the civilians in Syria. 

The new revelation by Syrian army comes as Russian officials blasted the west for its “naive” allegations of banned arms used by Syrian government forces. 

The Russian envoy to the United Nations (UN) said baseless allegations blaming Syrian government for applying chemical weapons are aimed at blocking efforts by the UN to probe into the use of chemical weapons in Syria.

"Unfortunately I think what our Western colleagues have been doing is trying to produce the maximum number of allegations with minimum credibility in an effort, one might think, to create maximum problems for arranging such an investigation," Vitaly Churkin stated.

He also refuted the charges by the US State Department that Russia is trying to prevent the UN from investigating the use of chemical weapons in Syria.

“The notion that Russia is blocking anything is completely misleading,” Churkin said, adding, “We have been doing everything we could in order to make sure that that investigations were to happen.”

On Tuesday, the Russian ambassador said firsthand evidence showed that militants, and not the Syrian army, manufactured sarin nerve gas and used it during an attack near the city of Aleppo in March.

Russian experts collected samples at the site of the attack in the region of Khan al-Assal, where over two dozen people, including 16 Syrian troops, died on March 19.
