Paris shooting another violent reaction to Prophet Muhammad depiction

While Muslim leaders around the world condemned Wednesday's Paris shooting attack on satirical newspaper Charlie Hebdo, it's not the first publication to be attacked for its treatment of the Prophet Muhammad.

When practicing the tenets of Islam, the vast majority of Muslims pray in peace, holding God above all else and his Prophet Muhammad in particular reverence.

"In any way, to touch the Prophet Muhammad or anything that would be seen as what we in the West call blasphemy is forbidden; it is not even remotely acceptable," said CBS News consultant Jere Van Dyk, who has travelled extensively across the Muslim world.

So when any image or depiction of the prophet surfaces, there is often anger, protest and, as seen Wednesday, violence.

In 1989, Iran's Ayatollah Khomeini called for author Salman Rushdie's assassination. His novel, "The Satanic Verses," was considered by some Muslims to be offensive in its depiction of Muhammad.

"We didn't know if this was just rhetoric or if it was something that was now going to be backed up with actual force," Rushdie said on "CBS This Morning: Saturday" in 2012.

In 2006, Europe saw large protests after a Danish newspaper published 12 cartoons of Muhammad, including one of the prophet with a bomb in his turban.

Comedy Central raised eyebrows in 2010 when it removed references to a character named Muhammad in a "South Park" episode. A radical Muslim group had warned creators Trey Parker and Matt Stone they risked being murdered if the episode aired.

And on the 11th anniversary of 9/11, anti-American riots spread in North Africa after a trailer for the movie "Innocence of Muslims" hit YouTube. It portrayed Muhammad as a womanizer and a thug.
