A new study from Tel Aviv University reveals attacks against Jews increased worldwide in 2009.

The study reveals that anti-Semitic incidents of physical violence more than doubled last year to more than 1,100.

"The year ... was the worst since monitoring of anti-Semitic manifestations began two decades ago, in terms of both major anti-Semitic violence and the hostile atmosphere generated worldwide by the mass demonstrations and verbal and visual expressions against Israel and the Jews," the study showed.

According to the report, most attacks occurred in Britain and France by Muslims angered by Israel's invasion of Gaza.

The report was released on the eve of Israel's annual Holocaust Remembrance Day.
