Mohammed Bouyeri assassinated Theo van Gogh, after the movie had been shown on Dutch TV. Bouyeri is a Moroccan-Dutch Muslim who was upset about the movie. The assassination happened on 2 November 2004. A letter linked the murder to Van Gogh's movie and his views regarding Islam. It was addressed to Ayaan Hirsi Ali and called for "jihad" against "kafir". Kafir is an Arabic word for unbeliever, a person who hides, denies, or covers the truth. The letter was also against America, Europe, the Netherlands, and Hirsi Ali herself. After the murder of Van Gogh, tens of thousands gathered in the center of Amsterdam to mourn Van Gogh's death. There were fire-bombings of mosques and Muslim schools. Christian churches were also attacked. Eleven other Muslim men were also arrested, other than Bouyeri. They were charged with conspiracy to assassinate Hirsi Ali.
