⚡️⚡️Azov regiment: Russia used poisonous substance against Ukrainian troops in Mariupol.
The substance has been distributed by a drone, and victims have shortness of breath and vestibulocerebellar ataxia.
It may be Russia's first known use of chemical weapons in Ukraine.
Video verified by The New York Times shows the bombardment of Chernihiv, Ukraine, on Thursday. As smoke cleared from the attack — which hit near apartments, pharmacies and a hospital — people are seen running in the street.
