Peruvian police on Tuesday burned about 11 tons of drugs confiscated in raids in recent months.
Colonel Carlos Reyes, head of the force's organized crime-fighting unit, said the drugs included 600 kilos (1,323 pounds) of cocaine base stashed in a home in Lima's La Molina neighborhood.
He said the drugs had been seized in a string of operations carried out between late 2013 and March 2014.
Several of the groups they were confiscated from were trying to export the banned substances to Mexican drug gangs, Reyes added.
"This was the first burning of drugs of the calendar year," he said.
Peru is currently the world's top producer of both coca leaves and cocaine, ahead of Colombia and Bolivia, according to the UN Office on Drugs and Crime.
