PARIS (AP) — Portraits of a Holocaust survivor tagged with swastikas. A memorial in honor of a Jewish man vandalized. A bagel shop with the German word "Juden" sprayed on its front window.

These are just a few of the hundreds of anti-Semitic acts that have been committed in France, which is home to Europe's biggest Jewish population, in recent months.

According to French authorities, the total of registered anti-Semitic acts rose to 541 in 2018 from 311 in 2017, a rise of 78 percent.

A judicial official told The Associated Press on Tuesday that four investigations have been opened by Paris prosecutor after the latest incidents in the French capital last weekend. The person was not authorized to be publicly named because the investigations are ongoing.
