Flags around the country flew half-staff and people laid flowers outside a cathedral Sunday in Norway, one month after suspected extremist Anders Behring Breivik allegedly killed 77 people on the island of Utoya. Norway's King Harald held a candlelit service inside Oslo's Spektrum arena, with appearances by some of Norway's top musical performers, including Susanne Sundfoer and rap group Karpe Diem. Prime Minister Jens Stoltenberg spoke to the audience, asking for unity. The names of the victims were read aloud for the first time. On Saturday, nearly 1,000 survivors and relatives were taken to Utoya to face painful memories at the scene of the massacre.
