On Friday at noon, an explosion occurred at the Gendarmerie Higher School 'Grl Br D Manuel María Calderón' in Monserrat, Buenos Aires. The blast happened when personnel opened a package that had arrived four months earlier and had been stored on the 11th floor of the building. Four officers were reported injured as a result, and medical staff provided immediate assistance.

The explosion's details reveal that it resulted from the handling of a parcel that was kept alongside two other packages, which had also been received by the institution. In response to the incident, an extensive security operation was activated in the Monserrat area. The security forces were prompt in their actions, securing the scene and assessing the risk from other potential explosives.

Officials have stated that an explosives brigade inspected the other packages to ensure safety and determine if there were any further threats. The incident raises concerns about security protocols regarding suspicious packages, especially in sensitive facilities like the Gendarmerie, and may lead to reviews of package handling procedures to prevent similar incidents from occurring in the future.
