Jewish schools in Australia are on high alert after eight drunken young anti-Semites stormed a school bus in Sydney on Wednesday and threatened to cut Jewish children’s throats.

Recent public statements by Venezuelan President Nicolas Maduro and other government officials about Israel are contributing to a climate of rising anti-Semitic expressions in Venezuela, the Anti-Defamation League (ADL) said.

The incident comes less than two weeks after the walls of Perth’s only Jewish school were painted with graffiti that read “Zionist scum.”

As Operation Protective Edge has progressed, protests in support of Palestine have drawn anti-Semitic protesters, mostly in France and Germany.

More than 100 anti-Semitic incidents have been reported to the Community Security Trust (CST) since the start of this month.

Algerian Mehdi Nemmouche, the man suspected of killing four people at the Jewish Museum in Brussels in May, has been charged with ''murder in a terrorist context.''

Police says three under suspicion for hailing Molotov cocktails at Wuppertal synagogue; attacked caused no injuries.

“Anti-Semitism today is hiding behind anti-Zionism.”

Israel’s ambassador to Germany, Yacov Hadas-Handelsman, said ‘’they pursue the Jews in the streets of Berlin… as if we were in 1938,’ as Jewish people have been attacked and abused on the streets of Germany in the last two weeks.

A former Deputy Shin Bet (Israel's security agency) chief has warned European diplomats that “if you do not stand by our side, the day when Islamic terror will reach your homes, your beds and your kindergartens will come soon.”
