Cucuta is located on the border with Venezuela and is the capital of North Santander state, where several criminal groups are fighting over drug trafficking routes and use the loosely patrolled border with Venezuela to smuggle fuel and weapons.
Last year a group of U.S. military trainers and advisers from the First Security Force Assistance Brigade spent time at the base that was bombed Tuesday with some also visiting another base located in the town of Tibu.
Videos posted on social media showed dark columns of smoke rising from the base followed by a loud explosion that shattered windows and destroyed offices.
The explosion comes as antigovernment protests appear to wind down in Colombia, with protest leaders announcing Tuesday that they will suspend marches that have been going on for seven weeks. At least 50 people have died in the protests over poverty and growing inequality, which started on April 28.
Molano said Tuesday’s explosion occurred shortly after 3 p.m. when men disguised as soldiers drove a white pick up truck into the base.
In 2019, a car bomb set off by the ELN at a police academy in Bogota, killed 21 people and prompted the government to end peace talks with the rebel group.
