Russia has alleged that the use of chemical weapons in Syria, spurring western nations to agree on arming Syrian rebels, was fired by rebels, and not by the Assad regime.
The Russians turned in their findings to the UN after studying samples of the site in which chemical weapons were used.
Russia's UN envoy Vladimir Churkin giving a statement claimed:
It was determined that on March 19 the rebels fired an unguided missile Bashair-3 at the town of Khan al-Assal, which has been under government control. The results of the analysis clearly show that the shell used in Khan al-Assal was not factory made and that it contained sarin.
The Russians also said that their study was based on direct samples taken from the site itself by Russian experts, unlike other studies done by western nations.
The official UN investigation into the attack itself, has excluded the Russians and Chinese from the process.
The U.S. accused the Syrian regime of using chemical weapons more than two months ago, though the evidence has been far from conclusive, with the U.S. even not outrightly confirming it was the Syrian regime that used them, rather saying they had varying degree of confidence that it was the Syrian regime.
