A government official says Poland is considering pulling out altogether from a visit to Israel over a comment made by the acting Israeli foreign minister, the latest in a bitter new Holocaust spat between the two nations.

Polish Prime Minister Mateusz Morawiecki already pulled out of the meeting Monday and Tuesday to Israeli Prime Minister Benjamin Netanyahu by leaders from Poland, Hungary, the Czech Republic and Slovakia. Foreign Minister Jacek Czaputowicz was tapped to go in his place.

On Monday, Michal Dworczyk, the head Morawiecki's office, said Czaputowicz's attendance is now in doubt over comments made by Israel Katz, the acting foreign minister.

Katz said Sunday that Poles "sucked anti-Semitism from their mothers' milk," citing something once said by former Prime Minister Yitzhak Shamir, whose father was murdered by Poles.
