Air defence missile systems have been deployed to a site in south-east London this morning, in preparation for a training excercise ahead of the Olympics.

On Monday, the MOD named six potential locations around the capital where missiles could be posted - to safeguard this summer's games.

Ria Chatterjee has sent this report from Blackheath, which is one of the areas on that list.
