A Norwegian court has extended by four weeks the isolation detention of Anders Behring Breivik, the man who confessed to the massacre of 77 people in July.
The Oslo court said 32-year-old Breivik must be kept in complete isolation by police, partly for fear he would tamper with evidence and contact possible accomplices.
Breivik had appeared earlier at a closed hearing under heavy police protection.
His earlier request to wear a long black tuxedo to the session had been rejected by the court, which described it as "unnecessarily disturbing and provocative."
The right-wing extremist has admitted killing eight people when he exploded a truck bomb outside government offices in Oslo, then fatally shooting 69 people at a governing Labor Party youth camp on Utoya island nearby.
Breivik denies criminal guilt, saying he believes the massacre was necessary to save Norway from Muslims and to punish politicians who have embraced multiculturalism.
The hearing came as survivors, relatives, and close friends of the victims were visiting Utoya on August 19-20 to grieve at the site of the massacre.
