VIACHA — Bolivian authorities confirmed seven deaths following an explosion at a military barracks in Viacha, Bolivia. Seven people remain missing as search operations continue at the site located about 30 km from La Paz.

The blast occurred on Friday, September 4, 2026, at approximately 2:30 p.m. local time in an area used to store pyrotechnic material. An artillery regiment is stationed at the barracks, which houses personnel from the Bolivar Regiment.

Army Commander Hector Alarcón stated that many personnel were away on a recreational bicycle ride when the explosion occurred. "Our priority remains finding our comrades who are still missing and providing answers to their families as soon as possible," Alarcón said.

Bolivian President Rodrigo Paz announced a period of national mourning and urged the public not to politicize the tragedy. Paz stated the cause of the blast appeared to be an accident caused by the improper handling of explosives. "Our armed forces are reviewing their protocols, and everything needed to provide greater safety, not only for enlisted personnel and officers, but also for nearby residents living close to military bases," Paz said.

Fourteen of the wounded were transferred to hospitals in La Paz, including a girl with third-degree burns. Police reported that dozens of homes were damaged, largely by windows shattered in the blast.

Police spokesman Roger Roca stated that fireworks had been stored at the barracks and that the cause of the blast remained under investigation. Firefighters warned that a heat source remained at the site, raising the risk of another explosion, and residents were urged to stay at least 150 meters away from the military base.

Viacha authorities declared three days of mourning following the incident. Prosecutors in Viacha have opened an investigation into possible manslaughter and other crimes, while investigators are also looking into how the explosives were stored.
