Sonja, the 88-year-old Queen of Norway, has been hospitalized due to heart problems. The Royal Palace announced this, noting that the Queen had already gone on a week-long medical leave on Sunday due to her medical condition – atrial fibrillation and heart failure. Sonja will remain hospitalized 'for a few days' for observation, while her husband, King Harald V, will continue his visit to provinces in the country as planned.
