Jerusalem - The Jewish Agency is bracing itself for the immigration of tens of thousands French Jews into Israel as a result of a growing anti-Semitism in France, a spokesperson for the organisation said on Sunday. ...

Vatikai said that a report compiled by the agency had found 30 000 out of France's 575 000-strong Jewish community were considering immigrating to Israel. ...

French Justice Minister Dominique Perben said last week that 180 anti-Jewish acts had been recorded so far this year, including cases of assault, arson and verbal insults. ...

Vatikai said the situation for French Jews was becoming increasingly "difficult".
