BOGOTA, Colombia _ In what Colombian President Ivan Duque termed a terrorist attack, an explosion at a police academy in the capital city of Bogota on Thursday left at least eight people dead and 54 wounded.
The explosion at the Francisco de Paula Santander Police Academy was caused by a car bomb that detonated near the entrance, according to a defense ministry statement. Wounded cadets were taken to Bogota hospitals, where officials issued an appeal for blood donations.
Suspicions as to who carried out the attack immediately centered on the leftist rebel groups National Liberation Army, known by its Spanish initials ELN, and Popular Liberation Army, or EPL. Both have been classified as terrorist groups by the U.S. government, but neither rebel group had taken responsibility by midday.
Colombia's largest rebel group, the Revolutionary Armed Forces of Colombia, or FARC, signed a peace deal in 2016, with 14,000 fighters and militia members demobilizing after a half-century of conflict. But the ELN and EPL remain at war with the Colombian government. Talks between the government and the ELN, the stronger of the two groups, have stalled over preconditions set by Duque.
Duque and defense minister Guillermo Botero arrived at the scene of the bombing by helicopter, where they were joined by several military and police officials to inspect the damage.
Addressing reporters at the academy, Duque slammed what he called a "cowardly attack" that targeted "unarmed students and youths."
"This terrorist act will not remain unpunished," he said. "We have always defeated terrorism. They will not make us give way. We will unite against violence and support the armed forces to capture and punish those responsible for this barbarity."
The car bomb was delivered aboard a light truck loaded with 180 pounds of Pentolite explosive, said attorney general Nestor Humberto Martinez, who appeared at the briefing with Duque.
After stopping and identifying himself at one of the academy's entrances, the driver drove through the checkpoint and continued for 300 yards inside the grounds before setting off the explosives, Martinez said. The force of the explosion broke windows in buildings several blocks away.
The truck had recently received a state-mandated inspection in the city of Arauca in eastern Colombia, on the border with Venezuela, Martinez said.
Television video images showed the vehicle's charred remnants.
"We will get to the bottom of the facts," Duque said in a statement issued earlier from Quibdo in northwestern Colombia, where he had been scheduled to host a meeting of national and local leaders, before he rushed back to Bogota.
Bogota Mayor Enrique Penalosa said that the bomb did not appear to be part of a coordinated series of attacks.
"All Colombians can be sure that we will not be intimidated by this terrorist act," Penalosa said. "All should unite against terrorism."
Names of the dead were not immediately released. But Ecuadorian President Lenin Moreno, in a statement on social media, said Ecuadorian citizen Erika Chico was killed.
While the FARC has transformed itself into a political party, Pastor Alape, a FARC spokesman and former leader during the years of conflict, said Thursday that the bombing appeared to be an effort by unnamed people to subvert a peace deal with the ELN and "delegitimize" social movements.
