Pupils at Islamic schools across Britain are being taught how to chop off a criminal's hand and that Jews are conspiring to take over the world, a BBC investigation has found.

Up to 5000 pupils aged between six and 18 are being taught Sharia law punishments using "weekend-school" text-books which claim those who do not believe in Islam will be subjected to "hellfire" in death.

A text book for 15-year-olds advises: "For thieves their hands will be cut off for a first offence, and their foot for a subsequent offence."

"The specified punishment of the thief is cutting off his right hand at the wrist. Then it is cauterised to prevent him from bleeding to death," it added.

Young pupils are warned that the punishment for engaging in homosexual acts is death by stoning, burning with fire or throwing off a cliff and that the "main goal" of the Jews is to "have control over the world and its resources."
