Amazon has removed books that deny the Holocaust from online stores in countries where Holocaust denial is illegal, but they remain available in the United States and the United Kingdom.

The British newspaper The Independent reported that the books were removed in some countries, including Italy, France and Germany, after Amazon was contacted about the sale of such books by The Sunday Times of London.

Among the books still available on Amazon’s U.S. and U.K. online stores are “Did Six Million Really Die?” by Richard Harwood; “The Six Million: Fact or Fiction?,” and “The Myth of the Extermination of the Jews.”
