A fire at a weapons factory in southeast Poland left one worker dead and another injured on Monday, local police spokesperson Jarosław Gwóźdź told CBS News.

There was no immediate information of the cause of the Monday morning fire at the Mesko weapons plant in the city of Skarżysko-Kamienn.

Gwóźdź said it was unclear whether the blaze had been caused by an explosion, as widely reported, but it sent shockwaves through the local community and raised concerns about safety protocols in Poland's arms industry.

The incident took place in one of the production units of the Mesko factory, igniting a fire that quickly spread through the facility. Emergency services arrived promptly, but by the time fire crews managed to douse the flames there was significant damage to the building.

The cause of the fire was under investigation, according to local police. Preliminary reports suggested it may have been triggered by a malfunction in production equipment, but officials did not immediately rule anything out. A team of experts, including representatives from the Polish government and independent safety inspectors, was assembled to carry out a thorough investigation into the incident, Gwóźdź told CBS News.
