What ? Cross-reference please

72.129.170.249 inserted this in 'Danish traditions':
"Shortly before the publication of the Muhammad cartoons, Jyllands-Posten ran a headline reading, “Islam is the Most Belligerent.” The newspaper ran an exposé about an alleged Muslim death-list of Jewish names—until it emerged that the whole thing was a fabrication. ."

I hope I'm not being blind to my blindspots. Although I generally find little to agree with J-P on, in terms of their editorial and political line, I find it highly unlikely that JP 'fabricated' the story about the death-list. That however, is the most immediate interpretation of the sentence (though I admit, there are several).  
Furthermore, I haven't heard of this before. Are there any cross-references ??
