An exploding tire led the driver of the unmarked police car carrying Swedish artist Lars Vilks, who had lived under police protection since his controversial 2007 sketch of the Prophet Muhammad, to lose control over the vehicle, which crashed head-on with a truck last year, Swedish authorities said Wednesday.
The crash killed three people, including the 75-year-old cartoonist. Since Vilks was facing death threats for his drawings, it raised the question of whether the crash was a terror attack instead of an accident.
