King Harald V of Norway has died at the age of 89, plunging the nation into mourning. A public condolence book was opened at Oslo City Hall at 10:00 local time, with additional locations throughout the country offering the same opportunity. Thousands of Norwegians gathered at Slottsplassen, the square in front of the Royal Palace, following the announcement, laying flowers and lighting candles. Oslo's mayor, Anne Lindboe, postponed her wedding to be the first to sign the register. The late King, known as "the king of the people," reigned since 1991 and was celebrated for modernizing the Norwegian monarchy. His passing occurred on what would have been his 58th wedding anniversary with Queen Sonja. The King’s body was transported from the hospital to the Royal Palace yesterday evening, and will remain there until the day of the funeral, with opportunities for the public to pay their respects.
