The National Liberation Army of Colombia

403785 06: A rebel nicknamed Comandante Lenin of the Colombian guerrilla group, National Liberation Army (ELN), reads a communique to journalists as the group released 11 civilians, including politicians and a priest to the Colombian Red Cross April 10, 2002 in the Arauca province of Colombia. The ELN guerrilla army said it was liberating the kidnap victims as a sign of good faith to continue peace talks with the Colombian government. The freed hostages delivered a message from the ELN that demanded that the Colombian government reject U.S. assistance to protect a critical oil pipeline. (Photo by Carlos Villalon/Getty Images)
