London attack: Victims 'startled to point they couldn't speak'

Police investigating Saturday night's terror attack in London say they know the identity of the three attackers who killed seven people and injured 48.

Dr Malik Ramadhan, divisional director of emergency care and trauma at the Royal London Hospital, where 12 of the victims were taken, says people were "startled to the point they couldn't speak," when they came into the hospital.

"People are ready," he told the Today programme.

Dr Ramadhan said hospital staff are preparing for attacks like this. They are staying completely sober because they believe there is a heightened risk and may need to help the public.
