British police officers take part in a mock chemical attack at Bank
underground station in central London, September 7, 2003. The exercise,
which does not involve members of the public or real chemicals and is
designed to test London's ability to cope with a terror attack, began at
1148 BST (British Summer Time) on Sunday and is designed to test the
response of the police, ambulance and fire services to such an incident. The
scenario being acted out is that a chemical is released on a busy train
travelling from Waterloo to Bank station in the heart of the City of London.
