Colombia on Monday publicly defended a dossier it says proves Venezuelan President Nicolas Maduro supports guerrilla groups and drug traffickers, but removed the armed forces' head of intelligence after widespread criticism of the report.

Colombia has long accused Maduro of sheltering rebel fighters and crime gang members. The allegations reached a fever pitch last month when several former commanders from the Revolutionary Armed Forces of Colombia (FARC) said they were re-arming in a video Colombian officials say was filmed in Venezuela.

President Ivan Duque announced in a speech to the United Nations General Assembly last week that he would give the organization a dossier of "conclusive proof," including photographs, of Maduro's support for terrorist groups.
