The Defense Ministry said the double detonation occurred at approximately 2.30 pm local time (1830GMT) at the General Maintenance Center of the RAM-2 "Bolivar" military base in Viacha. Defense Minister Ernesto Justiniano explained that the first blast "involved black powder corresponding to the pyrotechnic material stored in the place," followed by a second, far more powerful detonation, Anadolu Agency reported.
Of the 81 reported injuries, Justiniano confirmed that two are in critical condition. Regarding further potential casualties, Justiniano said he is not going to speculate as the removal of debris continues.
The Autonomous Municipal Government of Viacha, which is 22 kilometers (13.7 miles) southwest of the administrative seat of the government of La Paz, announced that the blasts affected an area within a 1-kilometer radius, resulting in widespread property damage and leaving hazardous ordnance exposed in public areas.
In response, municipal authorities declared three days of mourning to show solidarity with grieving families.
President Rodrigo Paz expressed his "deepest solidarity" and ordered authorities to conduct a thorough and transparent investigation. Paz emphasized that the government will not "speculate or rush to conclusions" about responsibilities.
