Colombia's government expects to begin talks within weeks with two dissident groups founded by former FARC rebels who reject that group's 2016 peace deal, the country's top peace official said.
President Gustavo Petro has vowed to end Colombia's 60-year conflict - which has killed at least 450,000 people - by inking peace or surrender deals with remaining rebels and crime gangs and by fully implementing the accord with the Revolutionary Armed Forces of Colombia (FARC).
