Seven people have been arrested and six addresses raided in London, Birmingham and elsewhere in connection with the Westminster terror attack, Mark Rowley, the Met's senior anti-terror officer, has revealed.

The police chief, speaking outside Scotland Yard this morning, also confirmed today that the official death toll is now four - including the attacker - despite claims last night that five people had died.

The four are PC Keith Palmer, two members of the public – a woman in her mid-40s, and a man in his mid-50s – and the attacker.

PC Palmer was stabbed and the other two victims were mown down on Westminster Bridge.

The attacker, who has not yet been named by the police, was shot in a police operation to prevent him gaining entry to the Houses of Parliament.

Mr Rowley said 29 casualties had been treated in five hospitals across London, with seven victims in a critical condition.

He reiterated that the police believe the attacker acted alone and that is was still his belief he was inspired by 'international terrorism' adding that there was no specific information to suggest any further threat to the public.
