The Duke of Edinburgh has been taken to hospital in Scotland as a precautionary measure, the third time he has been hospitalised in less than a year.
Buckingham Palace says Prince Philip, 91, was taken from the royal residence Balmoral to Aberdeen Royal Infirmary following a recurrence of a bladder infection.
The BBC reports he is not thought to be in a critical condition.
The Duke was last seen at public engagements in Cowes earlier this week.
Two months ago, Prince Philip was taken to hospital with a bladder infection, overshadowing four days of celebrations for the Queen's 60th year on the British throne.
He had an operation to clear a blocked heart artery in December last year and spent Christmas in hospital.
