A suspected Muslim extremist with alleged terrorist ties was under arrest Wednesday in the death of a Dutch filmmaker who criticized the treatment of women under Islam. Theo van Gogh, 47, was repeatedly shot and stabbed to death on an Amsterdam street on Tuesday. "Don't do it. Don't do it. Have mercy. Have mercy!" the Algemeen Dagblad newspaper quoted Van Gogh as begging his killer. Another Dutch newspaper, the Telegraaf daily, carried a large color photograph of Van Gogh's body with a knife protruding from his chest under the headline "Butchered.""We're not going to take this," the Dagblad said. The paper said the killer shot Van Gogh eight or nine times, then calmly bent over his victim and slit his throat with a knife. A police officer was slightly injured in the shooting. Police arrested a 26-year-old man with dual Moroccan-Dutch citizenship. His name was not released. The suspect is allegedly friends with Samir Azzouz, an 18-year-old Muslim of Moroccan origin awaiting trial on charges of planning a terrorist attack on targets including a nuclear reactor and Amsterdam's Schiphol Airport, NOS Dutch television reported. Dutch Justice Minister Piet Hein Donner said the suspect "acted out of radical Islamic fundamentalist convictions," and added that he had contacts with a group that was under surveillance by the Dutch secret service. The government held late-night crisis meetings and the Immigration Minister met with Muslim groups to discuss how to avoid violent confrontations with the Muslim community.
