Thailand burned more than 20 tonnes of confiscated narcotic drugs worth 6.45 billion baht (about US$175 million) on Wednesday (June 26) to mark the International Day Against Drug Abuse and Illicit Trafficking, authorities said, reported Xinhua.

The Food and Drug Administration (FDA) will incinerate huge amounts of drugs, including 61 million meth pills and 486kg of crystal meth, to mark the world's anti-narcotics day, the agency chief said on Friday.
