From Guardian:
"Justice Minister Piet Hein Donner said Thursday the note, stuck to the body with a knife, contained a ``direct warning'' to the screenwriter, Ayaan Hirsi Ali, a Somali-born member of parliament who has outraged fellow Muslims by criticizing Islamic customs and the failure of Muslim families to adopt Dutch ways. She had been under police protection before the slaying.
"Donner said the way the five-page letter ``was presented indicates that it is not from one person, but a movement.'' It was neatly typed and written in Dutch and Arabic. A testament found in the suspect's pocket was titled ``Drenched in blood'' and ``these are my last words.''
"The letter is titled ``Open Letter to Hirsi Ali'' and threatens a holy war against infidels, America, Europe, the Netherlands and Hirsi Ali. ``Saifu Deen alMuwahhied,'' or ``the unifying sword of religion'' is written at the bottom of the last page, apparently as a signature.
"``It is worrying because it gives the impression it is not the message of an individual, but a wider organization,'' Donner said. Security has been increased for individuals considered possible targets, including Hirsi Ali and members of her party, he said.
"The letter read that Islam would ``be victorious through the blood of martyrs.'' It contained apparent quotes from the Quran, and verses of poetry. ``Only the death will separate the truth from the lies,'' it said."
