Five suspected Islamist militants have been arrested for planning a gun attack at the Copenhagen offices of a Danish newspaper that printed cartoons of the Prophet Muhammad in 2005, police say.
The men intended to burst into the Jyllands-Posten office and kill as many people as possible, officials said.
Justice Minister Lars Barfoed said the "outrageous" plot was "the most serious attempt at terror so far in Denmark".
Four suspects were held in Denmark and the fifth was detained in Sweden.
Denmark's security agency Pet said the suspects included two Swedish residents with Tunisian backgrounds, one Lebanon-born Swede, and an Iraqi. The other was described only as Swedish.
Earlier this month, an Iraq-born Swedish Muslim blew himself up in Stockholm - apparently as he was preparing a suicide bombing.
Swedish police say the suspects held on Wednesday are not thought to be linked to the Stockholm bomber.
The publication of the cartoons in 2005, one of which depicted the Prophet Muhammad with a bomb-shaped turban, caused mass protests among Muslims across the world.
