Negotiators for Colombia's government and the largest rebel movement say they are taking steps to guarantee a ceasefire does not unravel while the two sides work together to save a peace accord defeated in a referendum.
At a joint press conference in Havana the two sides read a joint statement in which they pledged to listen to those who voted against the peace deal to "define quickly" a solution to the impasse in accordance with a recent constitutional court ruling.
The statement said: "The proposed adjustments and precisions that come about from this process will be discussed between the government and the Farc to provide guarantees to everyone."
The two sides invited the United Nations to begin monitoring a ceasefire already in place along the terms established in the accord so rebel fighters are not at risk.
The statement came as president Juan Manuel Santos was awarded the Nobel Peace Prize for his efforts to end a five-decade civil war that has killed more than 200,000 people.
Voters narrowly rejected the peace deal Mr Santos helped bring about with Rodrigo Londono, the leader of the Revolutionary Armed Forces of Colombia (Farc), after more than four years of negotiations.
