Westminster terror killer Khalid Masood died from a single shot to his chest, an inquest has been told.
Moments after he fatally stabbed PC Keith Palmer, the attacker was challenged by armed officers and shot dead inside the Parliament gates.
Brief details of how Masood's murderous rampage was brought to a dramatic end after 82 seconds were heard by a coroner on Thursday.
Senior investigating officer Detective Superintendent John Crossley, of the Counter Terror Command, told the hearing: "He attacked a police officer causing grave wounds, killing him. He was challenged by armed police and then shot and killed by another officer."
Coroner's officer Eric Sword said the provisional cause of death was "a gunshot wound to the chest".
He said Masood, 52, who was also known as Adrian Elms and Adrian Ajao, was identified by fingerprints and DNA.
The inquest heard that before he died, Masood drove his hire car across Westminster Bridge and mounted the pavement twice, "in an apparently deliberate attempt to target pedestrians".
The other victims killed were American tourist Kurt Cochran, 54, retired window cleaner Leslie Rhodes, 75, and college administrator Aysha Frade, 43.
More than 35 others were injured, including three police officers. Seven victims remain in hospital, one in a critical condition.
Westminster coroner Dr Fiona Wilcox expressed her sympathy to Masood's family, saying: "They are also victims of this incident."
None of Masood's family were in court, in contrast to the 10 relatives who attended earlier inquests into the deaths of his four main victims.
All the inquests have been adjourned until mid-May while police continue their investigation into the attack.
The Independent Police Complaints Commission is investigating the police shooting of Masood.
