British “historian” David Irving, who was jailed in Austria for denying the Holocaust, says he is in Poland to start a tour of World War II sites, including the former Treblinka death camp. “I am now in Warsaw and I am not at liberty to discuss my itinerary, as I am sure you understand for security reasons,” Irving told AFP on Tuesday via telephone. “I will be in Poland for the next nine days,” Irving said, confirming a week-long guided tour of World War II and Holocaust-related sites he is leading to Poland from September 21-29. It includes a visit to the former Treblinka death camp, in eastern Poland, where more than 800,000 people, mostly Jews, were murdered.
