World Leaders Offer Tributes to Britain's Prince Philip, Who Died at Age 99

LONDON - World leaders and members of the public have offered tributes to Prince Philip, the husband of Britain's Queen Elizabeth, who died Friday at the age of 99. 

On the gates of Buckingham Palace, a simple message was posted Friday morning: "It is with deep sorrow that Her Majesty The Queen has announced the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh."  Within hours, floral tributes began to pile up outside Buckingham Palace, the central London home of the royal family, and at Windsor Castle west of the capital, where Prince Philip passed away Friday.  "I think it's a huge loss, not only just because he's part of the royal family, but he's a husband, a father," said 31-year-old London resident Lisa Welsh, who was among those visiting Buckingham Palace on Friday. "He's been there for the queen through her whole reign, and I think the whole nation will be sad."
