Police guard the entrance of the address of the man identified by Norwegian police as the gunman and alleged bomber behind the attack on government buidlings and the Labour party youth camp in Oslo on July 23, 2011. At least 17 were killed in Friday's attacks in Norway, a bombing in central Oslo and a series of shootings on an island just outside the capital, and the figure could rise, a senior police officer said. Police had also found explosives on the island of Utoeya, where a gunman opened fire on young people at a summer camp organised by the ruling Labour Party, Sveinung Sponheim, acting commissioner for Oslo police, told reporters.
