Prince Philip is taken to the hospital in London with a bladder infection.

A statement from Buckingham Palace said the Duke of Edinburgh will be kept in for observation for a few days, meaning he will not be able to attend the rest of the Diamond Jubilee events.

The Queens Press Secretary issued a statement saying, "He is, understandably, disappointed about missing this evening's Diamond Jubilee Concert and tomorrow's engagements,"

The Duke will turn 91 this Sunday.
