A Saudi-run school in London uses textbooks which describe Jews as monkeys and Christians as pigs, according to papers filed with an employment tribunal by a former teacher.

Teaching materials used at the King Fahd school in Acton, west London, translated from Arabic for an unfair dismissal claim against the school, say Jews "engage in witchcraft and sorcery and obey Satan", and invite pupils to "name some repugnant characteristics of Jews" and to give examples of worthless religions, such as Judaism and Christianity.

Colin Cook, 57, a British convert to Islam who taught English at the school for 19 years until he was dismissed last December, said pupils had been heard saying they wanted to kill Americans, that 9/11 was good, and that Osama bin Laden was a hero. He is claiming £100,000 compensation for unfair dismissal, race discrimination and victimisation.

The school was originally set up to educate the children of Arab diplomats, but most of its 750 pupils are now British Muslims. It teaches Wahhabism, the dominant faith in Saudi Arabia, which is an extreme form of Islam that insists on a literal interpretation of the Qur'an.

Mr Cook's solicitor, Lawrence Davies, said he was taking the "extraordinary step" of issuing a statement because British pupils were being put at risk. "We are concerned at the fact that these racist textbooks are being taught in a Saudi-funded school to British pupils and to date no school inspection by Ofsted has identified this appalling practice."

The teacher, who earned £35,000 a year, says he blew the whistle to Edexcel, the examinations body, after children were allowed to refer to their annotated texts in an English language exam in breach of the rules. The school denies his allegations and claims he was rightly dismissed for misconduct. His tribunal hearing is expected to be held later this year.
