Poland is postponing moves to partially compensate families who lost property during the upheavals of Nazi occupation and communism.
Poland's chief rabbi, Michael Schudrich, criticised the government's decision to suspend work on a law designed to address the historical property claims of Jews and other Polish citizens.
"As a moral challenge, any government must face this challenge and should not walk away and I would hope that the Polish government could do the same," Rabbi Schudrich told the BBC.
