Moscow, SANA-Spokeswoman of the Russian Foreign Ministry Maria Zakharova said on Thursday that ISIS and Jabhat al-Nusra still use chemical weapons in Syria, astonishing at the absence of reactions by the western diplomats on the use of poisonous materials by gunmen against civilians and army soldiers.

“Russian Special experts in the chemical and biological weapons have found irrefutable evidence that document chemical attacks by terrorists, and this is not satisfactory for those who try to depict the armed groups in Aleppo as moderate opposition” Zakharova said at a weekly press conference.

She described the situation in Aleppo as “still difficult” as terrorists in the eastern neighborhoods of the city prevent civilians from leaving the city.
