Moroccan police have seized 23 tons of hashish hidden in machinery that was to be shipped to France.

Morocco's official MAP news agency said the drugs, hidden in industrial-sized grinders, were seized Friday on the premises of a transport company in Casablanca.

Saturday's report said it took police officials more than 24 hours to inventory the drug. It was hidden in nearly 130 fake grinders, each containing about 419 pounds of hashish.

The report said an investigation has been opened to find those behind the massive shipment.

Morocco's Interior Ministry is quoted as saying that last year Moroccan officials seized more than 110,000 tons of hashish.
