Russian and Syrian government have accused Syrian opposition fighters of launching chlorine gas attacks on Saturday 24 November night in government-held Syrian capital Aleppo. Syrian state news agency SANA reported that those chemical attacks left 107 people with ‘breathing difficulties’. Zaher Batal, the head of the Aleppo Doctors Syndicate, stated: “we suspected chlorine and treated patients on this basis because of the symptoms”. Nevertheless, the National Liberation Front (NLF) had dismissed the accusations, alleging that they do not possess poisonous gas. The veracity of the attack has not been verified by independent sources. French President Emmanuel Macron said he does not have “clear and sufficient evidence” on the gas attack, and at a press conference in Brussels, he stated: “I would like to ask those who spread these allegations to provide sufficient information on the matter”. The attack has sparked Russian strikes, and Russian defence ministry said on Sunday that warplanes were launched on “the identified positions of terrorist artillery in the area that shelled civilians in the city of Aleppo”.
