Danish media say several shots have been fired at a cafe in Copenhagen where a meeting about freedom of speech was being held, organized by Swedish artist Lars Vilks, who has faced numerous threats for caricaturing the Prophet Muhammad in 2007.

The TV2 channel said Saturday there were some 30 bullet holes in the window of the Krudttoenden cafe and said at least two people were taken away on stretchers, including a uniformed police officer.

Helle Merete Brix, one of the organizers of the event, told The Associated Press that Vilks was present at the event but not injured. When the artist is in Denmark, he receives police protection.

The cafe in northern Copenhagen, known for its jazz concerts, was hosting an event titled "Art, blasphemy and the freedom of expression" when the shots were fired.
