Victims of the Second World War Holocaust have filed a law suit in the United States against a German company, saying it helped the Nazis produce gas used in death camps and processed gold taken from the teeth of Jews.

The suit against Degussa AG seeks all its assets.

It alleges that Degussa told the Nazis it could refine gold dental fixtures into marketable gold.

The action also says Degussa was the joint owner of the company Degesch which produced the Zyklon-B cyanide tablets used to gas hundreds of thousands of concentration camp inmates.

A company spokesman said Degussa had to do what the Nazi government wanted.
