At least three people have reportedly been killed in an explosion at a publicly-owned weapons-manufacturing factory in the central Russian region of Nizhny Novgorod.
Russian news wires cited sources as saying that the blast ignited in a part of the Sverdlov chemicals and explosives manufacturing plant in Dzerzhinsk that worked with ammonal, an explosive material.
In a statement on its website, the factory said a ‘bang’ was heard at its mine disposal facility, after which the area was cordoned off.
An emergency source told the RIA Novosti state-run news agency that the explosion may have occurred because of safety violations.
Three people remain unaccounted for, reports said.
