London 2012: London flats 'possible Olympic missile site'

The Ministry of Defence says it is evaluating sites for surface-to-air missiles for the Olympic Games, and could place them at residential flats.

Residents at an estate in east London have received a leaflet saying soldiers could be placed there during the Games.

It says part of an air defence system might be based at a water tower on the estate, where 700 people live.
