Many residents in Humen township at the mouth of the Pearl River in Guangdong province cheered when more than 240 kilograms of seized drugs were burned in a grand ceremony on Thursday morning, marking the International Day Against Drug Abuse and Illicit Trafficking.

The drugs, which were burned at the square of the Humen Sea Battle Museum, included 100 kg of ketamine, 125 kg of methamphetamine and 17 kg of heroin.

All the drugs were seized by Dongguan police in a special campaign in the past few months, according to the Dongguan narcotics control commission on Thursday.
