The statements of the Iranian leadership at the conference underline once again the unacceptable character of the Iranian policy and underline the danger to Western civilisation as a whole from such a state.

We reject in the strongest terms conferences held in Iran on the supposed non-existence of the Holocaust.

Germany will never accept this and will use all possibilities at its disposal to oppose it.

I think it is such a symbol of sectarianism and hatred towards people of another religion, I find it just unbelievable.

I found that this conference that they had questioning the Holocaust is shocking beyond belief.

The Shoah (Holocaust) was an appalling tragedy which one cannot remain indifferent to.

The last century was witness to a bid to exterminate the Jewish people, the consequence being the murder of millions of Jews of all ages and social classes, simply for belonging to this people

The memory of these terrible events must remain as a warning to consciences in order to eliminate conflicts, to respect the legitimate rights of all people, to plead for peace with truth and with justice.

The United States condemns the conference on the Holocaust convoked by the Iranian regime on Monday in Tehran.

The gathering of Holocaust deniers in Tehran is an affront to the entire civilised world, as well as to the traditional Iranian values of tolerance and mutual respect.

I want to express publicly my shock and indignation.

In the face of this event, I want to state my firm condemnation of any attempt to deny, trivialise or minimise the Shoah (Holocaust) war crimes and crimes against humanity.

We are witnessing the re-emergence of revisionist ideas that are quite simply unacceptable.
