(35 minutes later)
Seven arrests have been made in raids following Westminster attack that left five dead, police have said. Seven arrests have been made in raids following the Westminster attack that left four dead, police have said.
Acting Deputy Commissioner and Head of Counter Terrorism Mark Rowley said the victims were a mix of nationalities. Acting Deputy Commissioner and Head of Counter Terrorism Mark Rowley said hundreds of detectives have worked through the night, carrying out searches at six addresses.
He added that seven of the injured were still in hospital in a critical condition. Those who died were a woman in her 40s, a man in his 50s, PC Keith Palmer and the attacker, he said.
Seven of the injured are still in hospital in a critical condition.
A further 29 had been treated in hospital, Mr Rowley added.
In the attack on Wednesday, a man drove a car along a pavement in Westminster knocking down pedestrians, leaving dozens injured.
He then stabbed a policeman and was shot dead by police in the grounds of Parliament.
In a statement made outside Scotland Yard, Mr Rowley said: "The inquiries in Birmingham, London and other parts of the country are continuing.
"It is still our belief - which continues to be borne out by our investigation - that this attacker acted alone and was inspired by international terrorism.
"To be explicit, at this stage we have no specific information about further threats to the public."
He said he would not name the bridge victims yet, who were "a mix of nationalities", and urged journalists not to publish the attacker's name while searches were continuing.
He said Londoners should expect to see more police officers on the streets, after officers' leave had been cancelled and duty hours extended.
It was initially thought that three members of the public had been killed on Westminster Bridge, but Mr Rowley referred to just two in his statement.
One of the raids by armed police, thought to be linked to the attack, took place in Hagley Road, Birmingham, on Wednesday night. A witness told the Press Association: "They came and arrested three men."
BBC Newsnight reported there was a suggestion the car used in the attack was hired from an address in Birmingham, although this has not been confirmed.
