Members of the FARC rebel group attend a news conference in Havana
Members of the Revolutionary Armed Forces of Colombia (FARC) rebel group (L-R) Tanja Nijmeijer of the Netherlands, Ricardo Tellez, FARC lead negotiator Ivan Marquez and Jesus Santrich attend a news conference in Havana December 21, 2012. Talks to end Colombia's bloody, half-century-long conflict with Marxist-led FARC rebels have made progress, but many challenges lie ahead, the government's top negotiator said on Friday. Former vice president Humberto de la Calle, speaking after the two sides finished their second round of meetings and broke until Jan. 14, said they had agreed on some "unprecedented mechanisms" for civic input into the peace process.
