At least four people have been killed after a major explosion rocked a manufacturing plant in the Russian city of Kopeysk on Wednesday, according to Aleksey Teksler, the governor of Chelyabinsk Region.

The incident appears not to be linked to any drone attacks, the governor stated, adding that there is also no threat to the city’s residents or the surrounding infrastructure.

A video obtained by RT shows the moment of the explosion and a fire ball rising over the facility.

Ukrainian drone attacks have been a concern in Russian regions in recent months. Kiev has routinely launched raids deep into the country, targeting critical infrastructure and residential areas in attacks that often led to civilian casualties.

This month alone, Ukrainian drone strikes have killed six civilians in Belgorod and Kherson regions, as well as causing a major power outage in Western Russia. Ukraine’s Vladimir Zelensky has also recently threatened Belgorod and Kursk regions with blackouts.

Russian officials have accused Ukraine of “terrorism” over the attacks. Moscow has launched retaliatory strikes on Ukrainian military sites in response, including drone assembly facilities.
