Three workers sustained light injuries in a strong explosion that rocked an ammunition plant's facilities in the Serbian town of Cacak on Saturday evening, state RTS television reported.
Police blocked access to the factory and ambulances and fire fighters were seen near the site of the blast, witnesses said.
The mayor of Cacak ordered the evacuation of people living near the factory, RTS reported. The three injured workers were hospitalised.
This is the second explosion this month at the Sloboda plant, which produces home appliances as well as artillery ammunition, propellants and explosives. No one was hurt in the previous blast, which occurred at the plant's warehouse.
A similar blast in 2003 killed three Sloboda workers, while one in 2010 also caused no casualties.
