The Explosion and Immediate Impact
On Friday, September 4, 2026, two successive detonations ripped through the Bolívar Mechanized Artillery Regiment’s storage area in Viacha, about 30 km southwest of La Paz. The blasts originated in a section used to store pyrotechnic material, including confiscated fireworks, grenades and TNT-based explosives. The shockwave shattered windows, damaged roofs and uprooted trees in nearby residential blocks, prompting the evacuation of dozens of homes to a temporary shelter.
Data & Statistics
- Confirmed deaths: reports range from two (Defense Minister Ernesto Justiniano) to nine (Bolivian authorities on September 5).
- Missing personnel: the Defense Ministry listed 14 missing; Army Commander Hector Alarcón later said seven remained unaccounted for.
- Injured: the Health Ministry’s latest figure is 84 treated, with 31 still hospitalized.
- Civilians among the injured: Defense Minister Justiniano noted 52 civilians.
Official Statements & Responses
President Rodrigo Paz announced a period of national mourning and pledged a “thorough, technical and transparent” investigation, saying preliminary information points to an accident linked to improper handling of stored explosives.
Defense Minister Ernesto Justiniano emphasized that the cause remains under investigation, describing the first blast as involving black-powder pyrotechnic material and noting that the material responsible for the second, larger detonation is still unidentified.
Health Minister Marcela Flores reported that 84 patients had received treatment since the explosions and that 31 remained in hospital care.
Army Commander Hector Alarcón said many soldiers were away on a recreational bicycle ride at the time, which “avoided a worse tragedy,” and highlighted the ongoing search for missing comrades.
Criticism & Opposition
Former President Evo Morales criticised the government’s handling of the disaster, accusing President Paz of mishandling the response and calling for the case to be referred to the International Criminal Court. Vice President Edmand Lara demanded a fuller, independent inquiry, arguing that the incident should not be reduced to a simple fireworks accident.
Conflicting Reports & Gaps
- Death toll: figures have varied from two to ten-plus, with nine most recently confirmed.
- Number missing: counts have shifted between seven and 14, with the latest report of seven still missing.

What Comes Next
Prosecutors in Viacha have opened a manslaughter investigation, and a multi-agency team—including the FELCC crime investigation police and the IDIF forensic institute—continues excavation and forensic analysis. President Paz has ordered that the investigation remain “transparent” and has asked for technical assistance from the United Nations system. No definitive timeline has been set for concluding the search for the missing soldiers or completing the technical inquiry.
