As part of a crackdown on the drugs trade in Peru, authorities have publicly destroyed five tonnes of illegal substances.

The cocaine-based drugs and marijuana were weighed and chemically tested for their purity in the capital Lima before being burned in an incinerator.

Peru is considered the world’s top producer of cocaine and coca by the United States and United Nations.

The UN estimated in 2008 that Peru makes some 300 tonnes of cocaine every year.
