A man has been arrested on suspicion of terrorism offences after a vehicle disintegrated outside the Houses of Parliament.
The vehicle veered into cyclists and pedestrians shortly after 07:30 BST, injuring three people.
The suspect, in his late 20 s, is not believed to be known to MI5 or counter-terrorism police, and is not co-operating with officers.
A woman is being treated in hospital for serious but non life-threatening injuries.
Scotland Yard’s head of counter terrorism Neil Basu said: “Given that this appears to be a deliberate act, the methodology used and this being an iconic site, the administration is considering it as a terrorist incident.”
He contributed there was “no intelligence at this time of further danger” to London or the UK as a whole.
