Norwegian national Mikael Davud, a member of China’s Uighur minority considered the mastermind behind the plot against the Jyllands-Posten daily, was sentenced to seven years behind bars, while Shawan Sadek Saeed Bujak, an Iraqi Kurd residing in Norway, received a three-and-a-half-year prison term.
Prosecutors had earlier recommended an 11-year prison sentence for Davud.
The two men had in liaison with al-Qaeda planned to use explosives against the offices of the Danish newspaper and to murder Kurt Westergaard, the cartoonist behind the most controversial of the 12 drawings of the Muslim Prophet published in September 2005, according to the prosecution.
The prosecution had demanded prison sentences of 11 and five years respectively.
David Jakobsen, an Uzbek arrested at the same time as Davud and Bujak in July 2010, was acquitted of the most serious charges but was sentenced to four months behind bars for helping the two others to procure the materials needed to create the explosives.
The three men had all pleaded not guilty to the charges.
Davud however did confess to planning an attack, but said it was directed at Chinese interests in Norway and not at Jyllands-Posten.
The member of the oppressed Uighur minority in China said he had been acting out of purely personal motives and that he had manipulated the two others so they would help him get hold of chemicals, including hydrogen peroxide, that he needed to build a bomb.
Bujak meanwhile admitted that he had spoken with Davud about the possibility of punishing Jyllands-Posten and Westergaard for the cartoons, but insisted the comments were vague and did not constitute a terrorist plot.
As for Jakobsen, who contacted police voluntarily in November 2009 and was the only one of the three to have been released from custody until the verdict, he categorically denied any intention to participate in the plot.
It was Norway’s first terrorism case with alleged international links. Under Norwegian law a charge of planning to commit a terrorist attack requires proof of a conspiracy between two or more people.
