The Italian government Wednesday searched for a port to unload a ship anchored off England's south coast carrying more than 2,000 tons of Italian industrial chemical waste, which has been barred from five countries.

The company charged with disposing of the toxic cargo will be given "the necessary instructions" to allay concerns that prompted British authorities to deny the ship permission to dock at Plymouth, England, the Italian Embassy said in a statement Tuesday.The British government said the 2,000-plus tons of highly toxic industrial chemicals, including a carcinogen, aboard the West German-owned Karin B were "essentially an Italian problem."

The cargo cannot be dumped in the United Kingdom because it is not known exactly what the 10,000 barrels aboard contain, said junior Environment Minister Virginia Bottomley.
