BOGOTA, Colombia (AP) — Colombia's president is moving quickly to hold a national referendum on a peace deal meant to end a half-century of bloody conflict with leftist rebels, delivering the final text of the deal to congress on Thursday and declaring a definitive cease-fire with the guerrillas.
"The armed conflict with the FARC is ending," President Juan Manuel Santos said on the steps of the congress building while declaring a definitive end to military action against the Revolutionary Armed Forces of Colombia.
Members of his family and Cabinet walked with him the short distance from his official residence to hand-deliver the 297-page accord to lawmakers, a move required for Colombia to hold a national referendum on the peace deal that Santos announced for Oct. 2.
The FARC declared a unilateral cease-fire over a year ago, but Santos refused to grant a formal truce until talks wrapped up, though he ended aerial bombardments of guerrilla camps,
The peace agreement was announced Wednesday after more than four years of grueling negotiations in Cuba. The cease-fire will take effect a midnight Monday, Santos said.
Colombians celebrated the historic agreement even while expressing doubts about whether the guerrillas they've grown to loathe will honor their commitments to lay down their weapons, confess human rights abuses and help eradicate illegal coca crops that helped fuel Colombia's conflict after insurgencies elsewhere in Latin America were defeated. The five-decade conflict has killed more than 220,000 people and driven more than 5 million from their homes.
Last-minute government concessions included guarantees that the FARC's still-unnamed political movement will have a minimum of 10 seats in congress for two legislative periods. After 2026, the former rebel must prove their political strength at the ballot box.
"We've won the most beautiful of all battles: the peace of Colombia," chief FARC negotiator, known by the nom de guerre of Ivan Marquez, said at the announcement in Havana.
Congratulations poured in from regional governments and the United Nations, which will play a key role keeping the peace. U.S. President Barack Obama also welcomed the deal.
The U.N. Security Council scheduled a meeting Friday morning to discuss the body's role in helping Colombian implement the deal.
"There is an important task ahead for the U.N. to assist the government of Colombia in implementing the peace agreement, which is a historic occasion," Britain's deputy U.N. ambassador Peter Wilson told reporters Thursday.
The accord commits Colombia's government to carrying out aggressive land reform, overhauling its anti-narcotics strategy and greatly expanding the state's presence in long-neglected areas.
The FARC was forced to the negotiating table in 2012 after a decade of heavy battlefield losses inflicted by the U.S.-backed military. Several top rebel commanders were killed and its ranks thinned by half to the current 7,000 guerrillas.
Polls say most Colombians loathe the rebel group, but surveys also indicate Colombians will likely endorse a deal.
The most contentious agreement would let rebels who confess their crimes avoid jail and instead serve reduced sentences of no more than eight years by helping rebuild communities hit by the conflict.
"There are no other words to describe that than as a pinata of impunity," said Jose Miguel Vivanco, the Americas director for Human Rights Watch.
Santos' plebiscite is not without risks.
Colombia's opposition is likely to try to convert the vote into a referendum on Santos, whose approval rating plummeted to 21 percent in May, according to a Gallup poll. That is the lowest since he took office in 2010.
Possible low voter turnout is also a concern because a minimum of 13 percent of the registered voters, or about 4.4 million voters, must vote in favor for the accord to be ratified.
"We think we've done the best possible job, but it's the Colombians who will judge us," said chief government negotiator Humberto de la Calle. "We have to wait for the citizens' verdict."
After the agreement is signed — the date is still unknown — the FARC will begin mobilizing its troops to 31 zones scattered across Colombia. Ninety days later they are supposed to begin handing their weapons over to U.N.-sponsored monitors.
Over the 13 months since the FARC declared a unilateral cease-fire and the government reciprocated with an unofficial truce, violence has fallen to the lowest level since the movement was created 52 years ago by outlaw peasant groups joined by communist activists.
But analysts worry that as the rebels integrate into Colombian society, well-organized criminal gangs will fill the void and fight among themselves for control of the country's lucrative cocaine trade, which kept the FARC well-armed much longer than other Latin American insurgencies.
The much-smaller National Liberation Army also remains active, although it's pursuing its own peace deal.
