Krystyna Pawlowicz, a lawmaker with Poland's ruling right-wing party, called it a "provocation."

Robert Bakiewicz, a far-right activist who organizes a yearly Independence Day march that government leaders joined last year, said "Christ died and was resurrected also for you, pagans and traitorous Jews."

Some came to Mosbacher's defense, recalling that Poland also has a small Jewish population. Poland was home to Europe's largest Jewish population before the Holocaust.

In February, the Visegrad summit in Israel was canceled after Poland pulled out over Israeli remarks regarding Polish complicity in the Holocaust, with Hungarian, Czech and Slovak leaders arriving in Israel for bilateral meetings instead.

Prime Minister Mateusz Morawiecki told reporters that Israel's interim Foreign Minister Yisrael Katz's remarks were "racist and unacceptable" and that "this is not something that can be left without a response."

Jewish leaders in Poland said they were offended Katz said Poles "suckled anti-Semitism with their mothers' milk."

The leaders issued a statement saying that accusing all Poles of anti-Semitism slighted thousands of Poles honored by Israel's Holocaust memorial center, Yad Vashem, for helping Jews during the Holocaust.
