Russia's UN ambassador Vitaly Churkin accused the Syrian militants of using chemical weapons in Aleppo, stressing that Russia has provided the United Nations Secretary General Ban Ki-moon with the necessary compelling evidence.

"I have just provided the Secretary General with the outcomes  of the Russian studies that were conducted on samples taken at Khan al-Assal site," Churkin said.

"The results of the analysis clearly indicate that the ordnance used in Khan al-Assal was not industrially manufactured and was filled with sarin [poison gas]," Churkin added.

The Syrian militants had launched on March 19 a number of shells on Khan al-Assal, which is under the control of the Syrian army, and killed 26 people.

Churkin pointed out that the samples were analyzed in a Russian laboratory which is approved by the Prohibition of the  Chemical Weapons Organization.
