U.S. Secretary of State John Kerry has met with representatives on both sides of Colombian peace talks in the Cuban capital.
A photo released by the Revolutionary Armed Forces of Colombia, or FARC, shows Kerry with guerrilla leaders, including the top commander, Rodrigo Londono, who goes by the nom de guerre Timochenko.
The FARC says in an open letter that it asked for Washington to consider it "a trustworthy partner in the building of a continental peace'' and recognize it as a political organization. The FARC is designated as a terrorist group by Washington.
Humberto de la Calle, the chief negotiator for the Colombian government, says the encounter with Kerry was "very productive.''
Talks have been going on in Havana since late 2012. Kerry's meeting came Monday as President Barack met with Cuban President Raul Castro.
