Secretary-General Guterres is “following very closely” the reports of alleged use of chemical weapons against civilians in Aleppo, according to a tweet posted by the UN spokesperson’s office on their official account, @UN_Spokesperson.

“Any confirmed use of such weapons, by any party to the conflict and under any circumstances, is abhorrent and a clear violation of international law,” the tweet added.

According to media reports, about one hundred people have been injured in recent fighting in Aleppo governorate.
