A summit of Central European leaders in Israel has been cancelled because of an Israel-Poland row over the Holocaust.
Poland withdrew after being angered by comments from Israeli leaders about Polish complicity in the Holocaust.
Polish Prime Minister Mateusz Morawiecki said Mr Katz’s remarks were seen as racist and unacceptable.
There was also Polish fury at Israeli Prime Minister Benjamin Netanyahu for saying Poles co-operated with the Germans during the Holocaust.
