A Russian airstrike hit a nitric acid tank in the frontline city of Sievierodonetsk, local governor Serhiy Gaidai said on Tuesday.
In a post on the Telegram app, he urged local residents not to leave bomb shelters due to the risk posed by toxic fumes from the acid tank.
Gaidai added a photo in which a large pink cloud could be seen over apartment buildings. He did not provide information on any casualties.
