A man carrying a knife is taken away by the police just after Norwegian Prime Minister Jens Stoltenberg (not seen) had arrived to meet survivors of the Utoeya island at a hotel where the survivors of the massacre at the Norwegian Labour Party youth summer camp are reunited with their families at Sundvolden, some 40 km south west of Oslo, on July 23 , 2011. At least 91 were killed in Friday's attacks in Norway, a bombing in central Oslo and a shooting spree 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.
