Explosion at Major Russian Explosives Plant Kills Six

Six people were killed and two injured in an explosion at a Russian explosives factory that produces industrial explosives.
The blast occurred during dismantling work and was likely caused by welding, possibly due to explosive remains in pipes.
The Promsintez plant is located in Chapayevsk in the Samara region of Russia.
Russia has seen several similar factory disasters in recent months from various causes.
The plant produces materials such as ammonal, nitric acid, and sulfuric acid.
