Eight people have been arrested in connection with the London terror attack, which left four people dead.
Westminster Bridge has reopened this afternoon, less than 24 hours after the attack occurred, police confirmed.
Two of the victims of the terrorist incident have been named today: US tourist Kurt Cochran and Londoner Aysha Frade, who was on her way across Westminster Bridge to collect her children from school. PC Keith Palmer was named last night as the police officer killed in the attack.
Police raids took place in London, Birmingham and elsewhere in the UK, deputy assistant commissioner Mark Rowley said this morning outside Scotland Yard. Seven were arrested following those raids, and just after 10.15am the Metropolitan Police confirmed an eighth arrest had been made.

He said that 29 people who had been injured in the attack on the Palace of Westminster, which left four people dead, had been treated. Seven people remain in a critical condition.
Politicians have returned to Westminster today, but the flag above the palace is flying at half mast. There will be a minute's silence to remember the victims of the attack at 9:30am.
The BBC reported this morning that armed police carried out a raid on Hagley Road in Birmingham last night.
London has been defiant in the aftermath of the attack, which took place at around 2.40pm yesterday afternoon.
The attacker drove a car along the pavement on Westminster bridge, knocking down pedestrians. He then collided into gates outside Parliament, ran into the courtyard inside the palace itself and stabbed a policeman. PC Keith Palmer later died of his injuries.
