The moat outside the Tower of London was lit up with 10,000 torches Sunday night, in a dazzling display to honor those killed in World War I.
The moving ceremony will continue every night through November 11, which marks Remembrance Day in the UK - the anniversary of the end of the Great War.
This year marks 100 years since the war's end, so Tower of London officials wanted to mark the event with a grand display.
