In late March, Damascus notified the UN Secretariat of the chemical attacks carried out by armed insurgents.
In a report RTR journalist Anastasia Popova confirms the use of toxic substances, apart from footage of the event, there are eyewitness accounts, reports from doctors who took care of the dead and injured and statements from experts from the University of Aleppo.
