KABUL, Dec. 21 (Xinhua) -- Afghan forces backed by the U.S.-led Coalition forces discovered and destroyed over two tons of drugs in a local school in southern Afghan province of Kandahar on Friday, said a Coalition statement released here on Sunday.
The combined forces were conducting a foot patrol and searching a school in Arghestan district where an estimated two-and-a-half tons of marijuana and a large room filled with marijuana seeds were found, the statement said.
With the help of local villagers, the drugs were taken outside of the school and destroyed, it said. Neither students nor school faculty were on the spot when the operation was going on, it added. "The combined forces also destroyed an improvised explosive device(IED) and an unexploded mortar round, both located approximately 100 meters from the school."
According to recent UN report, Afghanistan produces over 90 percent of the world's opium as Taliban militants will benefit nearly 500 million U.S. dollars from opium trade in 2008.
