Polish officials say they will not admit a research team Iran reportedly plans to send to Auschwitz, the notorious World War II Nazi death camp.

Polish Foreign Minister Stefan Mellar said his country should stop Iran from investigating the scale of the Holocaust, which Iranian President Mahmoud Ahmadinejad has dismissed as a myth.

The manager of the Auschwitz museum said Friday that deniers of the Holocaust profane the memory of its victims and will not be admitted.

Most estimates put the number of deaths at Auschwitz alone at more than one million, mostly Jews.

Earlier this week, Iran's ambassador to Portugal said he doubts the number of victims of the Holocaust, usually estimated at about six million. He said that, based on what he has seen at Auschwitz, it would take about 15 years to burn that number of bodies.
