Colombians are heading to the polls Sunday to vote in a presidential runoff election, choosing between Ivan Duque, of the Democratic Center party and Gustavo Petro, of the leftist Colombia Humana movement.
Outgoing President Juan Manuel Santos after voting in Bogota called the process a "momentous election," highlighting the fact that it was held in peace.
"In the last election's first round, a former FARC commander voted democratically for the first time ever," Santos said, referring to guerrilla chief-turned-political party leader, Rodrigo Londoño.
Duque - who remains ahead in the polls - has the backing of former President Alvaro Uribe, who said after casting his ballot that the Democratic Center party leader will protect Colombia.
"I voted for them (Duque and running mate Marta Lucia Ramirez) because they guarantee socially inclusive growth," Uribe said. "They are a guarantee that Colombia will not fall into the destructive clutches of socialism."
More than 7.5 million Colombians voted for Duque in the May 27 first-round election, while Petro received 4.8 million votes, which translates to 39.14 percent and 25.08 percent, respectively.
Authorities expect a peaceful election fostered not only by the standing peace agreement with the FARC, but also due to the five-day cease-fire ordered by the National Liberation Army (ELN) rebels.
