Crowds sing 'God Save the Queen' outside palace

STORY: Queen Elizabeth, Britain's longest-reigning monarch, the nation's figurehead and a towering presence on the world stage for seven decades, died peacefully at her home in Scotland on Thursday aged 96.

"The death of my beloved Mother, Her Majesty The Queen, is a moment of the greatest sadness for me and all members of my family," the new king, her eldest son Charles, said.

Buckingham Palace said Charles and his wife Camilla, the Queen Consort, would remain at Balmoral Castle, where the queen died, before returning to London on Friday.
