Colombia's FARC rebels have freed a former US marine who was kidnapped in June while he trekked through the jungle in a known guerrilla area, the Red Cross has said.
Kevin Scott Sutay, an Afghanistan war veteran, had been backpacking through several Central and South American countries before he was captured.
He had been warned by police to abandon his plans to hike through what they called a "red zone" for rebel activity.
Colombia's president Juan Manuel Santos has opened "explanatory talks" with the country's main revel group to try to end a 50-year-old conflict.
Mr Santos announced that talks will be supposedly held in Cuba, between representatives of his government and the left-wing Revolutionary Armed Forces of Colombia (FARC).
The government was able to secure congressional enactment in June of a "peace framework" law that would provide amnesty to rebel leaders.
