In Colombia, thousands of indigenous Colombians blocked a major southern highway Tuesday to protest a pending trade agreement with the United States. Organizers said the blockade drew more than 30,000 people. At least 30 people were reported injured when police used tear gas on the crowds. Government officials accused the demonstration of being a front for the rebel group the Revolutionary Armed Forces of Colombia — FARC. Indigenous leader Jose Antonio Catome had this response: “Here they are attacking us with helicopters. They are attacking also with bullets, that is, they are attacking in different ways as if we were an illegal group, and it is totally false that this was encouraged by the FARC. We take responsibility for this.”
