Poland’s foreign ministry has summoned the United States' ambassador in Warsaw demanded an apology, after the head of the FBI suggested that Poles bore some responsibility for the Holocaust.

FBI director James Comey suggested in a Washington Post article that some Poles were accomplices to the murders of World War Two, stating that,

“In their minds, the murderers and accomplices of Germany, and Poland, and Hungary, and so many, many other places didn’t do something evil. They convinced themselves it was the right thing to do, the thing they had to do.”

“That’s what people do,” continued Mr Comey. “And that should truly frighten us.”

His comments angered Poland with Prime Minister Ewa Kopacz saying it was “unacceptable”.

“To those who are incapable of presenting the historic truth in an honest way, I want to say that Poland was not a perpetrator but a victim of world war two,” Ms Kopacz said. “I would expect full historical knowledge from officials who speak on the matter.”

US ambassador Stephen Mull quickly apologised saying that Mr Comey’s words were “wrong, harmful and offensive,” adding that he "made clear that the opinion that Poland is in any way responsible for the Holocaust is not the position of the United States.”

"Nazi Germany alone bears responsibility,” said Mr Mull. “I now have a lot of work before me to make things right in this situation."
