As many as 150,000 Norwegians marched through Oslo Monday to pay tribute to the 76 people killed by an ultranationalist in gun and bomb attacks Friday.
Many participants in Monday's rally held white and red roses to mark the worst violence in Norway since the Nazi occupation in World War II.
The alleged gunman, Anders Behring Breivik, is accused of killing at least 68 people on the island of Utoeya, where hundreds of youths had gathered at a Labor Party summer camp. He went there after allegedly bombing a government building in Oslo, killing eight people.
Breivik made his first court appearance behind closed doors Monday. The judge later said Breivik admitted to the killings, but denied committing any crime. He claimed to be on a mission to "save Europe" from a Muslim takeover. Breivik accused the ruling Labor Party of betraying Norwegian culture by encouraging immigration
The court ordered him to be detained for eight weeks. He is to spend the first four weeks in solitary confinement. The judge said the detention is necessary to prevent Breivik from interfering with the police investigation. The judge also said authorities will investigate Breivik's claim that two other cells are planning more attacks.
The suspect's father, retired diplomat Jens Breivik, told reporters in France that he feels shame and wishes his son had killed himself instead.
Police significantly reduced the number of people confirmed dead in the attacks from 93 to 76. They say confusion at the attack sites led to the inflated death toll.
