The Blast
On September 4, two explosions ripped through the “Bolívar” mechanized artillery regiment’s maintenance centre in Viacha, about 30 km southwest of La Paz. The blasts detonated in an area used to store pyrotechnic material—including confiscated fireworks, grenades and TNT-based explosives—belonging to Bolivia’s Ministry of Defence. The first, smaller blast involved black powder; a second, larger explosion followed moments later. The shockwave shattered windows, damaged nearby homes and forced the evacuation of several blocks.
Background & Context
Bolivia’s armed forces maintain mandatory one-year service for 18- and 19-year-old conscripts. The Viacha barracks housed both active artillery personnel and civilian-type pyrotechnics, a practice that has drawn scrutiny after the incident. Prosecutors have opened a criminal investigation into possible manslaughter and other offenses related to the handling of the explosives.

President Paz’s decree of three days of official mourning remains in effect. Investigators, including a mobile forensic unit and drones, are mapping the blast site. Prosecutors have opened a case covering negligent homicide, negligent injury and reckless endangerment. Residents are instructed to remain at least 150 m away until the area is declared safe, and displaced families are being housed at the army’s Music School. The government has pledged to publish the investigation’s findings once completed.
