KABUL, Oct. 21 (Xinhua) -- Afghan authorities seized about 16 tons of drugs in the past 10 days across the country, local media quoted the country's top anti-narcotics official as saying on Saturday.

    Deputy Interior Minister Mohammed Daoud Daoud said the seizures included one ton of heroin, seven tons of opium and eight tons of marijuana.

    The authorities have arrested more than a dozen men involved in drug smuggling, he said, adding a campaign is under way to convince farmers not to grow the lucrative crop.

    Afghanistan will produce 6,100 tons of opium this year, witnessing a sharp rise of 49 percent from last year, according to a report by the UN Office on Drugs and Crime in September. This amount accounts for 92 percent of the world's total supply.
