2019 Bogotá car bombing

Attorney General Néstor Humberto Martínez identified the perpetrator as José Aldemar Rojas Rodríguez, known as "Mocho Kiko" because of his missing hand due to a previous explosion, a 57-year-old from the northern department of Boyacá.^[15][16][11] Rojas is alleged to have been involved with the ELN for three decades and served as an intelligence chief for a branch of the group.^[11] Since 2011, Rojas is alleged to have been teaching guerrilla militants in Venezuela how to construct explosives.^[11]

Ricardo Carvajal, who was previously investigated for drug trafficking in 2012 but was acquitted of the charges, allegedly contracted Rojas for the bombing due to his experience.^[17] The bombing, according to Colombian authorities, had been planned for more than ten months. In May 2018, Colombian records show that Rojas purchased a 1993 Nissan Patrol from Mauricio Mosquera, who was previously charged with terrorism and rebellion.^[10][12] On 27 July 2018, the vehicle was officially inspected in Arauca, Arauca, a city found on the border of Colombia and Venezuela where the ELN mainly controls territory.^[10][12]

The authorities stated that on 17 January 2019 at 9:30 am, Rojas drove his grey 1993 Nissan Patrol loaded with 80 kilograms (180 lb) of pentolite^[18] to the campus of the General Santander National Police Academy and dropped off a passenger at a nearby bus stop.^[10] Rojas then reportedly drove his truck down a side street used for deliveries to make his way onto the campus.^[10] When a detection dog signaled explosives on the vehicle, the driver forced his vehicle through a security checkpoint and struck security guards.^{[10][12][15][16][17]} The explosives in the truck were then detonated near the women's dormitories at the police academy as students were leaving a promotion ceremony.^[10][11][12] It is unknown if the driver detonated the explosives or if it was possibly the individual he left near the bus stop who remotely triggered the device.^[10]

In the immediate aftermath, the authorities began investigating Rojas's possible connections to either the National Liberation Army (ELN) guerrilla movement, the Clan Úsuga organized crime gang, or FARC dissidents.^[19]

On 18 January, Defence Minister Guillermo Botero identified Rojas Rodríguez as a long-time member of the ELN, within which he served as an explosives expert.^[15] Investigators were able to identify Rojas with security camera footage and fingerprints from his remaining hand.^[10]

A second individual, who Attorney General Martínez said "had participated in the attack", was arrested in Bogotá at 2:30 am on the day following the attack.^[20] The individual was identified as Ricardo Carvajal after he allegedly confessed to the bombings over a telephone call investigators intercepted.^[10][17] He was found with a "combatant's manual" and numerous coveralls.^[17] Carvajal Salgar denied that he was involved in the attack and his family stated that the coveralls were used for the jobs he worked.^[17]

According to Colombian authorities, there are on-going operations throughout Bogotá and the department of Arauca to capture other individuals suspected of having been involved in the attack, and that the ELN was responsible despite the organization not taking claim for the attack as it has done in the past.^[21]

President Iván Duque Márquez announced on 18 January that peace dialogue between the Government of Colombia and the ELN was officially suspended. Duque also demanded that Cuba extradite the ten ELN leaders that found refuge on the island nation during peace talks and the reactivation of their Interpol Red Notices, and he criticized Venezuela for providing refuge for the ELN on the Colombia-Venezuela border.^[11][22] In response to the request, Cuba's Foreign Minister announced that Cuba would abide by the protocols of ongoing negotiations between both parties.^[23]

The President of the National Constituent Assembly of Venezuela, Diosdado Cabello, denied any Venezuelan involvement in the attacks on 18 January.^[11] On 21 January, Colombian Foreign Minister Carlos Holmes Trujillo called for a "concrete response" from the government of Nicolás Maduro in Venezuela on whether the ELN was present in Venezuela, explaining that prior to the attack, the Colombian government asked the Venezuelan government on the potential presence of ELN groups in Venezuela without a response.^[24] Holmes Trujillo also stated that the Maduro government had taken "evasive positions" when speaking about the ELN.^[24]

ELN accepted the responsibility for the attack, saying the bombing was carried out in retaliation for the Colombian government not honoring the ceasefire by carrying out attacks on its camps. It justified that government and the cadres of its security forces had therefore become legitimate targets and called for resuming peace dialogue.^[6] High Peace Commissioner Miguel Ceballos spoke out against its members being sheltered anymore now that it had claimed responsibility.^[25]

A foreign national, identified as a female cadet from Ecuador, was killed in the attack, while three nationals from Panama, one from the United States and another also from Ecuador were wounded.^[26] Their respective governments have expressed their condemnation for the attack and assistance to their citizens.

• Cuba: Cuba shared condolences with Colombia, with its foreign ministry stating Cuba "will act with strict respect for the Protocols of Dialogue and Peace signed by the Government and the ELN, including the Protocol in Case of a Rupture in Negotiations".^[10]
• Ecuador: President Lenín Moreno lamented the death of Erika Chicó, the Ecuadorian cadet killed in the attack, and expressed his condolences to Colombia. He also announced that he was to send Vice President Otto Sonnenholzner to Bogotá accompanied by Chicó's relatives.^[27]
• Panama: The Panamanian embassy in Bogotá expressed its indignation at the attack, and provided a phone number for information about Panamanian cadets affected.^[28]
• United States: The Assistant Secretary of State for Western Hemisphere Affairs Kimberly Breier condemned the bombing and said: "Our condolences and sympathies go to the victims and family members of those killed", while the U.S. Embassy in Bogotá offered its "help in investigating this reprehensible attack".^[29]

Argentina,^[30] Brazil,^[31] Peru,^[32] Venezuela, and the Organization of American States^[33] also condemned the attack.
