A European Union study showed more than one in three European Jews have considered moving over the past five years because they no longer feel safe amid a surge in anti-Semitism.

The survey in 12 countries that are home to 96 percent of European Jews showed widespread concern at a rise in hate crimes which Jewish communities blame in part on anti-Semitic comments by politicians.

Facing hostility online and at work or in graffiti scrawled on walls near synagogues, nine out of ten Jews living in nations which have been their home for centuries feel that anti-Semitism has worsened over the past five years.
