PARIS — Despite desecrated Jewish graves in France and a deadly attack at a synagogue in Denmark, European leaders on Monday rejected calls from Israel’s leader for a mass migration of the continent’s Jews to Israel, urging unity instead.

Jewish tombstones were found vandalized in eastern France on Sunday, hours after a Jewish guard at a synagogue in Copenhagen was shot to death. Frenchmen have been accused of three deadly attacks on Jewish sites since 2012.

“I will not just let what was said in Israel pass, leading people to believe that Jews no longer have a place in Europe and in France in particular,” French President Francois Hollande said Monday.

French Prime Minister Manuel Valls said Monday the government would defend French Jews against what he called “Islamo-fascism.”
