The hospital received people who suffered from smoke and dust asphyxiation on the day of the alleged attack, Muwaffak Nasrim, a paramedic who was working in emergency care, said. The panic seen in footage provided by the White Helmets was caused mainly by people shouting about the alleged use of chemical weapons, Nasrim, who witnessed the chaotic scenes, added. No patients, however, displayed symptoms of chemical weapons exposure, he said.
