A National Ceremony of remembrance is taking place in the Norwegian capital Oslo today for the victims of massacres a month ago. A total of 77 people were killed in Oslo and in the island of Utoeya. The man who carried out the attacks is under custody. Survivors and relatives of victims had been joined at the ceremony by politicians, members of the emergency services and the Norwegian royal family. Yesterday several hundreds of survivors returned to the island. Some of them lit candles and laid handwritten notes in memory of their friends.
