Swedish artist Lars Vilks, who stirred worldwide controversy in 2007 with drawings depicting the Prophet Mohammad with the body of a dog, was killed in a car crash near the southern town of Markaryd on Sunday, police said.

Vilks, 75, who had been living under police protection since the drawings were published, was travelling in a police vehicle that collided with a truck. Two police officers were also killed.
