Britain's Prince Philip has been hospitalized.

The 90-year-old Duke of Edinburgh was taken to King Edward VII hospital in London from Windsor Castle as a "precautionary measure" after developing a bladder infection, Buckingham Palace has confirmed. The condition is not thought to be serious, although it means Philip will miss the remained of events planned to celebrate his wife Queen Elizabeth's Diamond Jubilee.

"The Duke of Edinburgh will not attend tonight's Diamond Jubilee. He has been admitted to hospital as a precautionary measure after developing a bladder infection," stated a series of tweets from the British Monarchy's official account.

Representatives from the palace have revealed he will be kept in for several days for observation. They added that the duke is disappointed to miss tonight's jubilee concert where acts from the queen's 60-year reign will perform, but the monarch will still attend. Philip will also miss tomorrow's Service of Thanksgiving.
