"It is with deep sadness that we announce the passing of His Majesty King Harald. King Harald passed away peacefully at the National Hospital [Rikshospitalet] on Friday, August 28, at 06:35" (05:35 in Lisbon), the palace said in a statement.

The longest-reigning monarch in Europe, Harald V, suffered from hemolytic anaemia, a blood disease that causes the abnormally rapid destruction of red blood cells, and had been hospitalised for about a week at the National Hospital in Oslo.
