An annual report by Tel Aviv University researchers shows that violent attacks around the world against Jews dropped in 2013 but warns that anti-Semitism is becoming more widespread in Europe.

The report, released Sunday, recorded 554 violent anti-Semitic acts in 2013, including attacks on people and vandalism against synagogues, cemeteries and other Jewish institutions.

The figures showed a 19 percent reduction compared to 2012, when a deadly shooting at a French Jewish school sparked a series of copycat attacks.

It said that anti-Semitic attitudes are becoming more acceptable, particularly among European youth, amid a rise in popularity of extremist parties in Hungary, Greece and elsewhere.
