Colombian President Juan Manuel Santos has said peace talks with the rebel National Liberation Army (ELN) will resume after a six-week halt.
Colombia was declared to have seen its elections progress with conservative parties ahead.
However, by late Sunday voters had already chosen the candidates from the right-wing and leftist coalitions who will contest the presidential election in May, following primaries held in parallel to the legislative vote. Final official results are expected later on Monday.
The former mayor of Bogota and representative of Colombia Humana, Gustavo Petro, and the candidate for the Uribe's Centro Democratico, Ivan Duque, were confirmed as candidates after winning the consultations of their respective parties.
Under the peace Agreement signed in November 2016, they're guaranteed ten Congressional seats in this Election. Patriotic Union, a political party founded by the FARC and Colombian Communist Party in the 1980s, was decimated by a campaign of violent attacks and assassinations blamed on right-wing death squads and drug lords.
Even though the Farc has been far behind from what was anticipated, the peace deal assures few seats to be won.
Opinion polls give the FARC little chance of adding to its 10 free seats, following a disastrous campaign during which its rebels-turned-politicians were largely drowned out by a tide of public revulsion over crimes committed during the conflict.
Finally, Almagro reiterated the unbreakable commitment of the hemispheric organization to continue to accompany social and institutional efforts to build peace through the Mission to Support the Peace Process (MAPP/OAS), which is celebrating 14 years of uninterrupted work in the most isolated territories and those most affected by armed violence in Colombia.
"We are convinced that dialogue is the best path to peace".
