From the BBC:

Danish newspapers have reprinted a caricature satirising the Prophet Muhammad which sparked violent protests across the Muslim world two years ago.

They say they wanted to show their commitment to freedom of speech after an alleged plot to kill one of the cartoonist who drew 12 caricatures.

Three suspects were held in Denmark on Tuesday "to prevent a murder linked to terrorism", officials said.

The cartoons were originally published by Jyllands-Posten in September 2005.

Danish embassies were attacked around the world and dozens died in riots that followed.
