Excerpt:
Artist Lars Vilks, who caused controversy by drawing cartoons that depicted the prophet Muhammad as a dog, has been attacked while giving a lecture at Uppsala University.
Vilks, who has been the subject of numerous death threats, was attacked while speaking at the university's philosophy faculty on Tuesday afternoon. He was not badly hurt.
"The man was sitting in the front row and suddenly came rushing towards me. He headbutted me, and I was thrown against the wall and dropped my glasses," he said.
