Prince Philip, the Duke of Edinburgh died on Friday, just two months shy of his 100th birthday.

In a brief statement, the royal family said, "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.

"His Royal Highness passed away peacefully this morning at Windsor Castle."

Since news of the death broke, outpourings of support have come from world leaders and friends of the royal family.

Here's what they have said:

Prince Philip's children

Prince Philip's children — Prince Charles, Princess Anne, Prince Andrew and Prince Edward — paid tribute to their father in a pre-recorded documentary last night, saying the Duke would like to be remembered as an individual “in his own right”.

"He didn’t suffer fools gladly so if you said anything that was in any way ambiguous, he’d go ‘make up your mind’, so perhaps it made you choose your words carefully," Prince Charles said. "He was very good at showing you how to do things and instructing you how to do things."

“My father was always a great source of support, encouragement and guidance. Never trying to control the activities we wanted to do, but always encouraging us,” Prince Edward said.

“He was a person you could bounce ideas off and if you were having problems you knew you could go to him. There was a lot of leeway allowed in pushing your own boundaries,” Princess Anne added.

“Without him, life will be completely different. From society’s perspective, he was able to keep pace with the kind of technological changes that have such an impact… but above all that it’s not about the technology it’s about the people.”
