An explosion and fire broke out at the Avangard polymer plant in Shakhty, Rostov Oblast, Russia, on Wednesday, injuring at least nine people, Russia’s state-controlled TASS reported. The factory, opened in June 2023, is Russia’s first polyester plant.
A string of Ukrainian drone attacks has taken place on Russian factories connected to the war effort in recent months; however, this incident has no confirmation of a drone attack.
The moment of the explosion in the Shakhty poliester plant is reportedly shown on this video, circulated by Russian TG channels. Russian authorities deny any drone attack on the plant, but locals are heard discussing a possible attack on videos
