A Norwegian court in Oslo will continue hearing a criminal case against Anders Behring Breivik, the self-confessed perpetrator of Norway\'s twin terror attacks, on Friday. The court will consider extending Breivik\'s four-week period of isolation, a statement published on the court\'s website said. The hearing will begin at 1:00 pm local time (11:00 GMT) and will take place behind closed doors. The first hearing into the killing of 77 people by the 32-year-old anti-Muslim extremist on July 22 was held late last month. The court has ordered the eight-month arrest for Breivik, including four weeks of complete isolation. Breivik has confessed to killing eight people with a car bomb in downtown Oslo before shooting dead 69 others on the island of Utoya, where the governing Labor Party\'s youth branch hosted the summer camp, on July 22. He could be jailed for up to 30 years if convicted.
