As per local authorities cited by RIA Novosti, the origin of the explosion was traced back to a pyrotechnics warehouse that had been rented by a third-party company operating on the premises of the plant. This occurrence was classified as a "breach of established technological protocols".
Preliminary information, reported by TASS, has indicated that the explosion was not the result of unmanned aerial vehicles (UAVs), commonly known as military drones. Such drones have been utilized by both Ukrainian and Russian forces to carry out attacks on opposing territories. It is unclear at this time whether Russian authorities suspect foul play or military activity.
The impact of the explosion was significant enough to result in a blast wave which shattered windows in the surrounding area, according to additional information from TASS.
Following the incident, the Ministry of Emergency Situations reported that two of the injured individuals required hospitalization.
