Colombia's top criminal gangs, who are linked to producing and trafficking cocaine, on Thursday proposed a ceasefire to the incoming government of leftist Gustavo Petro as a starting point to peace talks, six groups said in a statement.
The groups, which are spread throughout Colombia, are accused by the current government of killing social leaders and attacking the Andean country's military as part of a strategy to control coca crops - the chief ingredient in cocaine - as well as labs for producing the drug and trafficking routes.
