London, Great Britain – Ken Livingstone, Mayor of London, said: ‘London has been the target of a cowardly terrorist attack. Londoners have responded calmly and courageously.

‘I commend the professionalism, courage of the Metropolitan Police, Transport for London staff, the Ambulance, Fire and other emergency services.

‘On behalf of all Londoners, I want to express my deepest sympathies to the families and friends of those who have been killed and to all of those who have been injured.

‘The Police, transport and emergency services are carrying out well-rehearsed plans to treat and evacuate casualties and protect London against any further attacks.

‘The most important thing Londoners can do today is to assist the Police and Emergency Services in every possible way: by staying totally calm, by not travelling until the Police advise that it is safe to do so and by not calling the emergency services unless life is threatened.

‘Innocent people from all of London’s communities have been targeted by this indiscriminate attack. I urge Londoners from all of this city’s diverse communities and faiths to support one another and stand together against terrorism.’
