Free clinic set up in Columbia
ARAUCA, Colombia -- The high fever and sores spreading over her son's skin had been worrying Jensi Rojas for days, but she could not afford to take him to a doctor. So when a group of medics, including six from the U.S. military, set up a makeshift clinic inside a school in this town in eastern Colombia, Rojas brought in her 8-year-old son.
