Ecuadorian Indians are taking legal action in federal court here, charging that a U.S. company that was contracted to carry out fumigation of illicit crops in neighboring Colombia recklessly sprayed their homes and farms, causing illnesses and deaths, and destroying crops. U.S.-based attorneys representing 10,000 individuals living in the Amazon rainforest near the border with Colombia filed a class action complaint against Virginia-based DynCorp Corporation in federal court here Sep. 11. A DynCorp spokesperson said the company has not been notified about the complaint and declined to comment further.
