"Two Syrian military servicemen were killed. Not less than 37 civilians were injured."
A statement released by the Russian Foreign Ministry earlier on Monday condemned the attacks, saying "this instance of combat use of chemicals by the terrorists against the civilians is not, unfortunately, an isolated case…
"We strongly condemn the terrorist attack using toxic substances against the civilians in Aleppo."
The leadership of the Syrian Arab Army issued a statement earlier Monday saying that al-Nusra Front killed at least 84 people and injured 280 in Aleppo during the past three days, taking advantage of the ceasefire.
Al-Nusra Front terrorists and some Syrian rebel groups, allied to the group, launched an offensive in Aleppo's south-west on Friday. For more than three days, terrorists have been attacking Syrian Arab Army's units, as well as residential areas in western and central parts of Aleppo.
