He said a fire at the plant, which he did not name, had been extinguished.

Russian investigators said on Thursday that they had opened a criminal case into the incident.

Local media, citing eyewitnesses, reported that the explosion had occurred at the 'Plastmass' plant, which is controlled by Russian state corporation Rostec.

There was no indication that the incident was linked in any way to drone activity, the governor, Teksler, said.

Rostec was not available for immediate comment.
