"The ISIL has used toxic gases in its attacks against the Iraqi forces in Western Iraq, specially Ramadi, on November 23," the Arabic-language service of Sputnik news agency quoted an unnamed Iraqi security source as saying on Tuesday. This is not the first time the Takfiri terrorists use poisonous gases, including mustard gas, against the Iraqi soldiers in Ramadi city. In August, an Iraqi official disclosed that the ISIL used the poisonous mustard gas during withdrawal from Al-Anbar University. "The Iraqi troops were exposed to mustard gas in the munitions fired by the ISIL as they were winning back the Anbar University," Samir al-Shavili, a media advisor of Iraq's Counter-Terrorism, told FNA. He said after a thorough physical examination of the Iraqi soldiers who had taken part in Anbar university operation it came to be known that the ISIL had used mustard gas against the Iraqi forces.
