A Saudi Arabian school in Vienna has been accused of indoctrinating students with anti-Semitic material, allegedly teaching outlandish and arcane conspiracy theories as history.

The school board in the Austrian capital said an investigation has been opened into the Saudi School, a private non-religious institute run by the Saudi government.

The probe was sparked by a report by Austrian magazine News, which alleged that a history book used at the school contained anti-Semitic material.

"The Freemasons were a secret, subversive Jewish organisation, which aimed to secure Jewish control of the world," a passage of the textbook read, according to the report.

The school board has demanded the institute produces a certified German translation of all its teaching material, The Local reported.

If the allegations are proven correct, the Saudi School, which has students from Middle Eastern families living in Vienna, might lose its status as a recognised educational institution.
