CONFESSED MASS KILLER Anders Behring Breivik has been ordered to stay in pretrial detention for a further eight weeks – four of which will be in solitary confinement.

Four weeks is the maximum amount of time that a person can be held in solitary confinement in Norway before their case must be reviewed, according to NPR.

The decision was made during a hearing today, the BBC reports. Breivik can now be held in total isolation until 17 October and has been banned visitors or correspondence until 14 November.

The 32-year-old Norwegian right-wing extremist has confessed to setting off a bomb in central Oslo and to opening fire on a youth camp on the island of Utoya, killing a total of 77 people, last July.

While admitting to the attack, Breivik has denied criminal guilt – saying that his actions were necessary to prevent Norway being taken over by Muslim extremists and multiculturalism.

Breivik has expressed no remorse for his actions so far, according to his lawyer Geir Lippestad, reports USA Today.
