Colombia's police stand guard in front of a Venezuelan helicopter bearing Red Cross insignias siting on the tarmac at the airport in Villavicencio, Colombia, Monday, Dec. 31, 2007. Helicopters sent by Venezuela's government sat idle for a fourth consecutive day on the edge of Colombia's vast jungles, waiting for guerrillas to name the spot where they are expected to hand over three hostages: former congresswoman Consuelo Gonzalez, Clara Rojas and her 3-year old son Emmanuel.
