Poland's prime minister says his country is not sending a delegation to a meeting in Jerusalem after the acting Israeli foreign minister said that Poles "collaborated with the Nazis" and "sucked anti-Semitism from their mothers' milk".
The developments mark a new low in a bitter conflict over how to remember and characterise Polish actions toward Jews during the German occupation of Poland in World War II.
Polish Prime Minister Mateusz Morawiecki called the remarks by acting foreign minister Israel Katz "unacceptable" and "racist".
Morawiecki had already announced on Sunday that he was pulling out of the meeting in Israel on Monday and Tuesday with Israeli Prime Minister Benjamin Netanyahu and leaders of four central European nations.
That had followed a comment by Netanyahu last week about Polish cooperation with the Nazis.
