Colombian government troops pursued a battered guerrilla column through the mountains yesterday after reportedly killing about 60 rebels in one of the military’s biggest battlefield victories in years. U.S.-made Black Hawk helicopters were central in the attack. In addition, the chief of Colombia’s military said technical intelligence allowed the military to track the rebel column before the battle erupted. He did not say where the technical intelligence was coming from, but the United States can gain such information from its spy planes and satellite imagery. The U.S. Embassy said it had no immediate comment on whether the U.S. was providing this information.
