Thai authorities have seized crystal methamphetamine with a street value of almost $30 million stuffed inside boxing punch bags bound for Australia, officials said Reuters reported.

More than 193 kg of the drugs, also known as “ice,” were hidden among 15 different bags.

Methamphetamine production in Southeast Asia's Golden Triangle—a border region between Thailand, Laos, and Myanmar—has been increasing sharply in recent years, according to the United Nations Office on Drugs and Crime.
