An explosion and fire at a petrochemical plant in Russia’s republic of Tatarstan killed at least two workers and injured dozens more, the facility’s owner said Tuesday.

The blast occurred at Nizhnekamskneftekhim, Russia’s largest producer of synthetic rubber and plastics, located in the industrial city of Nizhnekamsk, around 170 kilometers (105 miles) east of Kazan.

Sibur, the petrochemical company that owns the plant, said the explosion was likely caused by an “equipment malfunction.” It said injured workers were receiving medical care and that the facility had been evacuated.

Tatarstan’s prosecutor’s office said it had launched a preliminary investigation and could pursue criminal charges if safety violations are found.

Videos circulating on social media showed a large plume of smoke rising over Nizhnekamsk, while Mayor Radmir Belyayev said the blast wave shattered windows in nearby homes.

Russian media reported that residents smelled a chemical odor in the air after the incident, though Sibur said monitoring showed no threat to public safety or the environment.

A Message from The Moscow Times:

Dear readers,

We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."

These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.

We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.

Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.

By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
