Colombian President Ivan Duque announced on Sunday, in an impromptu press conference with military and police leaders, that the country’s security forces killed Andres Felipe Vanegas London, one of the top commanders of the National Liberation Army (ELN).

The operation took place in the jungle commune of Novita, in the province of Choco located along the northwest Pacific coast. 

President Duque, who was dressed casually in jeans and delivered the conference from Choco, said that, “This criminal was killed in a meticulous operation of shared intelligence by the national army of Colombia and the national police.” 

London had been responsible for kidnappings, murders of human rights activists, killings of security forces’ members, and forced recruitment of minors. The terrorist leader, who went by the nom de guerre “Uriel,” was widely known for his media appearances, online videos, and one-time Twitter account.
