UPPSALA: A Swedish cartoonist whose sketch of the Prophet Mohammed enraged many Muslims, was attacked while giving a lecture about freedom of speech.
Lars Vilks says he was head-butted by an audience member as he spoke about the limits of artistic freedom at the University of Uppsala. The cartoonist's glasses were broken, but he was not injured.
Vilks said a group of about 15 people had been shouting and trying to interrupt the lecture, which was attended by about 250 people.
In March, Vilks was the target of an alleged murder plot involving Colleen LaRose, an American who called herself "Jihad Jane".
Earlier in January, a Somali man was indicted for attempted murder for breaking into Vilk's home and threatening him with an axe.
