French anti-terrorism authorities Friday opened an inquiry into death threats against a philosophy teacher who has been forced into hiding over a newspaper column attacking Islam, legal officials said.
Robert Redeker, 52, is receiving round-the-clock police protection and changing addresses every two days, after publishing an article describing the Koran as a "book of extraordinary violence" and Islam as "a religion which ... exalts violence and hate".
He told i-TV television he had received several e-mail threats targeting himself and his wife and three children, and that his photograph and address were available on several Islamist Internet sites.
"There is a very clear map of how to get to my home, with the words: 'This pig must have his head cut off'," he said.
Speaking on RMC radio, Prime Minister Dominique de Villepin said such threats were "unacceptable".
