Queen Elizabeth II has died, aged 96. The British monarch passed away quietly at her Balmoral residence in Scotland with her family by her side. On Thursday, it was announced that the royal was "under medical supervision" because her doctors were "concerned" for her health. The day before, the Queen postponed an online meeting of the Privy Council, during which new U.K. Prime Minister Liz Truss would have taken her oath as First Lord of the Treasury, due to medical advice.
