BOGOTA (Reuters) - Colombia's peace talks with Marxist FARC rebels have reached a "critical" stage, with discussions over the next couple of months a key gauge of whether an end to five decades of war is likely or not, government negotiator Sergio Jaramillo said on Tuesday.
The government has spent almost 10 months working through a difficult peace agenda in Cuba with representatives of the FARC, or Revolutionary Armed Forces of Colombia. While some progress has been made, talks have been painstakingly slow and most now see the hoped-for year-end deadline as unlikely.
"We are currently in a critical moment of negotiations, I think that in the next months we will know if this is going to work or not because we are beginning on essential issues," Jaramillo, one of the six-man government negotiating team, said during an address in congress.
President Juan Manuel Santos said from the very beginning he did not want the talks to drag on indefinitely, putting a November limit on completion. He has since loosened the target date to year-end or some months later.
Unused to seeing rebel leaders taking center stage and making televised political statements and demands on the government, Colombians have grown impatient over the last few months at the pace of talks.
Meanwhile, the rebels have continued to kill scores of soldiers and attack economic infrastructure, putting additional pressure on Santos to clinch a deal.
The center-right president took a huge risk seeking peace after numerous attempts by previous governments ended in failure and bolstered the group's fighting force. The talks have already dominated his agenda and threaten to overwhelm campaigning for next year's presidential election.
"Let's see how we can accelerate these conversations, time is short, people want peace but demand that we advance more quickly," said Santos during the inauguration of a military hospital in Bogota.
The official agenda includes rebel participation in politics, an end to the conflict, how to eliminate the drug trade, reparations for victims and agrarian reform - on which the two sides have reached partial accord.
Government negotiators have said it could take as long as a decade to implement the accords.
The war, which began in 1964 and led to as many as 200,000 deaths, has pit the FARC and a smaller rebel group, the ELN, against government troops and illegal paramilitary death squads.
The FARC has sought to overthrow a dozen governments since it began as an agrarian struggle against rural inequality. Even while it has been severely weakened in the past 10 years by a heavy U.S.-backed offensive, the leftist guerrilla movement remains a formidable threat to the government and civilian population.
Santos wants any agreement reached in Havana to be ratified by popular vote. If the voters do not like the way peace is achieved and how it would impact the nation, the accords would be moot, Santos has said.
