The Syrian government has denied chemical weapons were used in the Damascus area on 21 August, while its allies Russia and Iran have blamed opposition elements.
The chemical attacks were allegedly carried out in opposition-controlled areas on the outskirts of the capital in the early morning of 21 August and coincided with shelling and bombing by the Syrian military. More videos were released throughout the day showing dozens of corpses and casualties suffering symptoms associated with various chemical warfare agents. Fatality estimates varied wildly between 130-1,300.
Syrian Information Minister Omran al-Zoubi rejected claims that the military had carried out chemical attacks, arguing that ongoing ground operations in the allegedly affected areas would have made it operationally impossible to use such weapons.
