ISTANBUL, Turkey?Seven suspects have been arraigned in Turkey in connection with the seizure of an estimated $29 million worth of unrefined morphine from Afghanistan.

Some 7.5 tons of crude morphine, an opium extract used to produce heroin, were confiscated over the weekend in a raid on carpenter’s studio in a village in the northwestern province of Sakarya.

Police said the amount was the largest seized in a single raid anywhere in the world, a claim that could not immediately be confirmed.

By Tuesday an Iranian and six Turks had been arraigned in Istanbul on smuggling charges stemming from the drug haul. Another suspect was released on bail and four others detained in the operation were set free, the Anatolia agency said.

Maj. Gen. Abdulkadir Yilmaz of the paramilitary police said the drugs were found hidden in packets of macaroni and salami.
