Four years ago, Danish cartoonist Kurt Westergaard triggered a bitter clash of cultures with a cartoon depicting the Prophet Muhammad. On New Year's Day, a young Muslim from Somalia tried to kill him with a knife and an axe.

The publication of the cartoons in the Jyllands-Posten newspaper in September 2005 caused uproar in the Muslim world. The protests claimed 150 lives.

In October 2009, two Chicago men were charged with plotting terrorist attacks against targets including Jyllands-Posten.
