Danish newspapers have reprinted one of several caricatures of the Prophet Muhammad which sparked violent protests across the Muslim world in 2005.
They say they wanted to show their commitment to freedom of speech after an alleged plot to kill one of the cartoonists behind the drawings.
Of three suspects detained over the alleged plot on Tuesday, one - a Danish citizen - was released on Wednesday.
The remaining two - Tunisian citizens - are set to be deported without trial.
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.
Jyllands-Posten and many other major newspapers, including Politiken and Berlingske Tidende, reprinted the caricature in their Wednesday editions.
The cartoon depicts Muhammad wearing a turban shaped like a bomb with a lit fuse.
The editors said no-one should feel their life was threatened because of a drawing.
"We are doing this to document what is at stake in this case, and to unambiguously back and support the freedom of speech that we as a newspaper will always defend," Berlingske Tidende said.
The cartoon was also broadcast on national television, and even newspapers that were originally against the publication of the caricatures are now backing the campaign to defend freedom of speech, says the BBC's Thomas Buch-Andersen in Copenhagen.
No strong reactions to the republication had been observed, a foreign ministry official told news agency AP.
