London:
Tourists outside Buckingham Palace were treated to a mass dance routine on Monday in honour of the recent royal wedding.
More than 100 dancers emerged from the crowds outside the palace gates to perform routines to a mix of tunes including "We Will Rock You" by Queen.
A participant said the routine used urban dance techniques to celebrate the wedding of Prince William and Kate Middleton.
The seemingly spontaneous flashmob was arranged by the palace to mark a reception honouring young people in the performing arts.
Most of the dancers were students from the University of East London.
