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.
In particular, Israel's acting Foreign Minister Yisrael Katz used the phrase, "Poles imbibe anti-Semitism with their mother's milk".
Nazi Germany murdered six million Jews, mostly in Poland. Some Poles did collaborate with the Nazis.
Mr Katz's remarks were "racist and unacceptable", Polish Prime Minister Mateusz Morawiecki said.
