Queen Elizabeth II’s death is being mourned in the United Kingdom and across the globe. The country’s longest-reigning king passed away on Thursday at the age of 96.

Crowds gathered outside Buckingham Palace in central London, as condolences came in from all across the nation and the globe. The royal family flew to Scotland to be at the queen’s side after Buckingham Palace announced that she had been put under medical monitoring.

Few Britons have known another queen, so the end of Elizabeth’s reign after more than 70 years will usher in days of sadness and an unknown new period for the royal family and Britain.

The country’s new monarch, King Charles III, has issued a statement and will address the nation on Friday.
