Queen Elizabeth II, who ruled the UK for 70 years, passed away at Balmoral at the age of 96.

The death of Queen Elizabeth II is being mourned in Britain and across the world. At age 96, the king with the longest reign in the nation passed away on Thursday.

While condolences came in from all around the nation and the world, significant crowds gathered in front of Buckingham Palace in the heart of London. As the royal family hastened to Scotland to be by the queen's side following Buckingham Palace's announcement that she had been placed under medical supervision, concerns about her health had been growing.

Few people in Britain have ever known another queen, so when Elizabeth's more than 70-year reign comes to an end, it will usher in an unknown new period for the royal family as well as for Britain.

King Charles III, the nation's next monarch, has issued a statement and will address the people on Friday.

Senior royals had convened in Balmoral because the Queen's doctors had expressed worry earlier in the day about her health.

After doctors placed the Queen under medical monitoring, all of the Queen's children made their way to Balmoral, which is close to Aberdeen.

Prince William, the future heir to the throne, and her grandson, as well as Prince Harry, gathered there.

Prime Minister Truss: The nation and the globe were shocked greatly by the passing of the Queen.

The prime minister issued the following statement in Downing Street: "We are all grieved by the news we have just heard from Balmoral. Her Majesty the Queen's passing has shocked the entire country and the entire globe." The cornerstone upon which modern Britain was erected was Queen Elizabeth II.
