(MOSCOW) -- Moscow is alleging that Syrian rebels were likely responsible for a deadly chemical attack outside the city of Aleppo last March that left 27 people dead and dozens more wounded.
Vitaly Churkin, Russia's permanent United Nations representative, said a report has been sent to Secretary General Ban Ki-moon.
According to Churkin, Russian experts visited the area of Khan al-Assal upon the request of Damascus and it was determined that the deadly agent sarin was carried by a "Bashair-3 unguided projectile."
Moscow ascertained that the weapon was produced by a rebel group affiliated with the Free Syrian Army called the Bashair al-Nasr Brigade.
This would mark the first time that the Syrian opposition has been directly accused by a foreign government of deploying chemical weapons. The U.S., Great Britain, France and Israel have all concluded that Syrian President Bashar al-Assad's military has used chemical weapons on a limited basis in his fight to stay in power.
As for the U.N., its Human Rights Council's Independent International Commission of Inquiry says "limited quantities of toxic chemicals" were used at Khan al-Assal, as well as in three other attacks.
However, since Damascus won't allow international inspectors to check these areas, the U.N. says it can't "determine the precise chemical agents used, their delivery systems or the perpetrator."
