At approximately 1510 local time (2010 UTC) on 15 June 2021, a vehicle-borne improvised explosive device detonated inside the barracks of the 30th Brigade of the National Army in the city of Cúcuta, located near the Venezuelan border approximately 200 km (125 mi) northeast of Bucaramanga. Reports indicate that two individuals impersonating public officials drove a pickup truck into the military facility and left the vehicle on the premises. The truck exploded shortly thereafter, followed by a second blast stemming from the same vehicle. A total of 36 people were injured in the explosions, including two civilians. Three of the victims were critically wounded, while 29 others suffered minor injuries. According to the U.S. Embassy in Bogotá, a small number of U.S. military personnel were present at the base; however, none of them suffered serious injuries. Authorities have detained one person in relation to the attack. Colombia’s defense minister stated that either the National Liberation Army (ELN) insurgent group or dissidents of the Revolutionary Armed Forces of Colombia likely perpetrated the attack.
