An explosion occurred on Tuesday afternoon in the A28 ammunition depot of the Tehnicki Remontni Zavod in Kragujevac, central Serbia, that killed one person.

The Ministry of Defense announced this on Tuesday evening, adding that three more persons are listed as missing, while 25 members of the Serbian Army (VS) and the Interior Ministry (MUP) have been injured.

The victim has been named as Lt. Colonel Miroslav Perisic.

The depot where the blast happened on Tuesday afternoon was used to store a large quantity of rifle grenades and other ammunition.

The military institution overhauls and produces ammunition, ammunition elements and mining explosive items. The daily Blic reported earlier in the day that there was a second blast and that the roof on the building collapsed, trapping an unknown number of people.

The explosives in the depot were being prepared for dissembling and safe destruction. The police in Kragujevac said there was no need to evacuate a nearby residential area.

NATO Secretary-General Jens Stoltenberg has offered Serbia his condolences after a blast at a Serbian defense factory killed one person and injured dozens on Tuesday.

“As the Serbian authorities are working to establish the facts of this tragedy, I want to convey NATO’s solidarity at this difficult time,” Stoltenberg said in a statement.

The NATO chief reiterated that Serbia was the bloc’s “valued partner.”

“The Alliance remains committed to helping the countries of the Western Balkans, including Serbia, to safely store their weapon stocks and to destroy dangerous surplus ammunition,” he said.
