Istanbul, Turkey - Alas, it happened again. An extremist Muslim attacked a Westerner to punish him for mocking Islam. This time, the victim was the Danish cartoonist Kurt Westergaard, whose controversial caricature of the Prophet Muhammad had sparked a worldwide storm five years ago.

A 28-year-old man of Somali origin broke into the cartoonist’s home a few weeks ago, wielding an axe and a knife.
