(CNN) Chelsea owner Roman Abramovich is donating $5m to the Jewish Agency For Israel in a bid to help fight anti-Semitism across the world, the organization said Thursday.

The Russian billionaire's donation is the largest ever received by the body, which helps Jewish communities across the world, according to a spokesperson.

Isaac Herzog, chairman of JAFI, said Abramovich's generous donation came as "Jews are once again unsafe on the streets of Europe."

"I applaud Roman Abramovich for taking strong initiative to combat anti-Semitism and am grateful for his contribution to the Jewish Agency's efforts to ensure Jews are safe in their communities around the world," Herzog said in a statement.
