Angry Muslims.

Some might suggest that it would take a lot for a former nazi to become unpopular in the Middle East, but look at the pope and the furore over his remarks on faith and reason last week. Those such as the Guardian's Madelaine Bunting who perpetuate the myth that the rioting in response to Pope's innocuous comments reflect upon him would surely struggle to explain incidents like this:

The authorities in Nigeria’s northern state of Jigawa have imposed a nighttime curfew in the wake of a violent protest by a group of Muslim youths in the state capital. The rioters attacked Christians following a blasphemous statement allegedly made by a local Christian woman about Prophet Muhammad.
.....

At least 10 churches, 20 shops as well as homes of Christians were reportedly attacked and set ablaze by the angry protestors, who claimed a local Christian woman had made a blasphemous statement about Prophet Muhammad. The woman was said to have reacted to inflammatory language denigrating Jesus Christ by a Muslim man.

So muslims man starts berating a woman about her religion she answers back, so mobs of local muslims launch a pogrom against christians. There is no doubt that at the moment much of the islamic world takes the attitude that they are entitled to launch the most vicious assaults on infidels and heretics wheras the slightest response to this behaviour can justify almost any savagery in response.
