Pakistani officials say customs authorities have destroyed more than 23 tons of hashish, heroin and other drugs worth millions of dollars as part of the country's anti-narcotics drive.
A senior customs official, Mussarat Jabeen, said the drugs were confiscated over the past three years.
The official said the drugs were burned near the southern port city of Karachi, and included 23 tons of hashish and 243 kilograms of heroin.
Drug traffickers often use Pakistan as a transit point for drugs destined mainly for lucrative markets in Europe. Pakistani authorities believe most of the drugs originate in Afghanistan, the world's largest producer of opium.
