Wordy,
The trouble is it's not individuals doing it. It's a large group. In separate locations. At separate times. All in the name of their religion.
It's not exactly an isolated incident or a rare occurance is it?
You only answered part of my post, why did you ignore the International Red Cresent part?
To answer your question.....Compared to how many muslims there are in the world? Yes this is extremely rare.
So now I've answered your question will you comment on the link to the International Red Cresent I provided as a counter to your arguement?
