BUDAPEST, Hungary (AP) — The Federation of Hungarian Jewish Communities said Sunday it will boycott all government events commemorating the 70th anniversary of the Holocaust in Hungary unless the government cancels some of the planned memorials.

The dispute stems from historical and ideological differences between the federation and Prime Minister Viktor Orban’s government about the yearlong series of remembrances centered on the 1944 deportation of more than 430,000 Hungarian Jews to Nazi death camps.
