A city employee carries a bag of cocaine to an incinerator at a police base in Lima, Peru, a small part of the more than 4 tons of drugs seized in March and April - including cocaine, marijuana and heroin - that were burned there. Increased drug trafficking in Peru has been driven, in part, by the success of a U.S.-backed operation last decade that pushed operations out of Colombia into its neighbor to the south. Now, the U.S. is helping the Peruvian government fight the same battles. (Associated Press)
