OSLO (AFP) - Anders Behring Breivik, who has confessed to the twin attacks in Norway on July 22, claims he called police during the massacre of 69 people on the island of Utoeya, his lawyer told Norwegian public broadcaster NRK on Monday. "He has explained (during a police interrogation Friday) that he called police from Utoeya, but I don't know if that is the case," said Geir Lippestad, who is defending the 32-year-old rightwing extremist. A call to police could explain some witness accounts from survivors of the bloodbath, saying they heard Behring Breivik speaking on the phone or a walkie-talkie. Most of the 69 people killed on the island were teenagers attending a youth summer camp hosted by the ruling Labour Party, while another eight people were killed earlier after Behring Breivik set off a car bomb outside government offices in the capital. Oslo police could not be immediately reached for comment on Behring Breivik's claim he called them. They meanwhile said earlier Monday they had gathered all the mobile phones, computers and cameras found on Utoeya as evidence, and were analysing them to trace the killer's movements on the island.
