French leaders say they will defend the Jewish community against attacks, after growing unease and calls from the Israeli leader for a mass immigration.

French President Francois Hollande said Monday he will not allow people to believe that "Jews no longer have a place in Europe" after this weekend's deadly shooting at a Danish synagogue and the desecration of hundreds of graves at a Jewish cemetery in eastern France.

European Jews were already on edge after the killings in January at a kosher market in Paris and a shooting at a Belgian Jewish museum last year.

French Prime Minister Manuel Valls also said Monday that the government would defend French Jews, saying that every person who leaves "is a piece of France that is gone."
