Four men have gone on trial accused of planning an armed attack on a Danish newspaper that printed cartoons of the Prophet Muhammad.
Prosecutors said the men had plotted to open fire on the offices of Jyllands-Posten on the day that Crown Prince Frederik was due to visit the building.
The four had intended to cause heavy loss of life, they said, but the prince was not thought to be the target.
The men have denied terrorism and illegal possession of weapons.
Jyllands-Posten published the cartoons of Islam's holiest figure in 2005, sparking riots in Muslim countries.
The three Swedish citizens and a Tunisian were detained in December 2010 in Denmark and Sweden.
Munir Awad, Omar Abdallah Aboelazm and Munir Ben Mohamed Dhahri, a Tunisian citizen, were picked up by police on 29 December 2010 at a flat near the Danish capital, Copenhagen.
