PERU DOWNS SUSPECTED DRUG-RUNNING PLANE OVER AMAZON LIMA, July 18 (Reuters) - Peruvian air force fighter jets have shot down a light plane on a suspected drug-running flight over the Amazon near the country's border with Brazil in the first such incident in two years, authorities said on Tuesday. The jets sprayed machine gun fire into the small plane after it ignored warning shots on Monday over the jungle about 520 miles (840 km) northeast of Lima around Ucayali, a smuggling area in this major drug-producing South American nation, an air force official said. Peruvian police were searching for debris from the plane and the fate of the occupants was not known. The air force has shot down more than 20 planes in the 1990s but this was the first since 1998. Peru has won praise for reducing its coca crop by more than half since 1995 as a military air blockade guided by U.S. radar severed one of the principal smuggling arteries from Peru to Colombia, where most coca is processed into cocaine. Under pressure from the air force, many smugglers switched routes, hauling the semi-processed coca paste by mule over the jungle or ferrying it in boats along remote tributaries in the Peru's Amazon, a dense rain forest about the size of Texas. - --- MAP posted-by: Richard Lake
