October 17 (SeeNews) - Six people were injured in an accident at the manufacturing plant of Bulgarian arms producer Arsenal in Kazanlak, the interior ministry said on Wednesday.
One of the workers was severely injured, while the other five suffered minor injuries, the ministry said in a statement.
All six have been hospitalised.
In March, one person died and another was severely injured in a fire that broke out at the plant in Kazanlak, in central Bulgaria.
In 2016, two workers died in an explosion at the plant that occurred during repair works at one of the plant's buildings.
Arsenal manufactures small arms, sub-machine guns, artillery systems, rocket launchers and ammunition. An explosion at the plant in 2012 caused no casualties.
