Colombians gather in Bogota's Bolivar Square on Sept. 26, 2016, to celebrate the historic peace agreement between the Colombian government and the Revolutionary Armed Forces of Colombia, or FARC.
Colombians will have the final say on endorsing or rejecting the accord in the Oct. 2 referendum. Opinion polls point to an almost-certain victory for the "yes" vote.

Santos, who for years was the FARC's top military opponent, proclaimed that the signing of the accord will put an end to generations of bloody combat that has killed more than 220,000 and displaced millions, creating the conditions for wounds to heal and the country to prosper in the years ahead.
FARC rebels and supporters watch a live broadcast of the peace agreement signing ceremony while in Colombia's Yari Plains, a remote area of southern Colombia where the group recently concluded its last congress as a guerrilla army by endorsing the deal.
