- Terrorist killed four pedestrians when he drove car along pavement on bridge
- He then rushed the gates of Parliament and stabbed to death a police officer
- Coroner opens inquests into the victims' deaths with a minute's silence today
- Victims families pay heartbreaking tributes to them on first day of the inquest
- Court shown CCTV of final moments of victims and as the terrorist struck
CCTV footage shows an American couple walking across Westminster Bridge seconds before a terrorist drove onto the pavement and killed the husband.
Tourist Kurt Cochran, 54, was one of four people murdered when Muslim convert Khalid Masood launched his attack in the shadow of Big Ben in March last year.
Mr Cochran's final action was to push his wife Melissa out of the way of Masood's rented 4x4. He was thrown into the air and fatally injured, dying at the scene.
In a statement read to the court by Mr Cochran's sister-in-law, Angela Stoll, his wife Melissa said: 'I am forever grateful for the time we had together, allowing me to be the mother to his children and especially his heroic actions on that day, saving my life.'
Retired window cleaner Leslie Rhodes, 75, Aysha Frade, 44, and Romanian tourist Andreea Cristea, 31, were also killed by Masood's car on the bridge. PC Keith Palmer was stabbed inside the gates of Parliament.
Families of all of the victims left court as the disturbing footage of their loved one's final moments were played to the coroner.
Mrs Cochran described her husband as 'my inspiration, my rock star, and most of all my hero', adding: 'We wish everyone had Kurt's love and compassion for others.
'No words will bring Kurt back or anyone else who has died senselessly in such cowardly attacks on humanity.'
Opening the inquest into the victims' deaths today, Chief Coroner Mark Lucraft QC said: 'The lives of many were torn apart by 82 seconds of high and terrible drama.'
He asked the court to observe a minute's silence for those who died.
Disturbing CCTV footage shown to the hearing showed Masood driving across the bridge, before he stabbed PC Palmer as he lay prone against a low wall was also shown.
After inflicting the fatal blows, Masood is apparently distracted by another officer, giving Pc Palmer the chance to run away.
At the start of the hearing, each bereaved family gave a touching 'pen portrait' of their loved one at the inquest.
PC Palmer's sister said he had joined the police to make a difference and loved his role guarding the Palaces of Westminster.
Chief Inspector Neil Sawyer said: 'His brave actions that day did not surprise me. Keith never backed away from a job protecting people.'
Aysha Frade's husband John told the inquest 'lived and breathed for her daughters', and struck a balance 'between tender care and discipline'.
He said his wife, whose smile was like the sun 'popping out from behind a cloud', had been 'cruelly and brutally ripped away' from the family.
Detective Superintendent John Crossley told the coroner how each of the victims was fatally injured.
Masood mounted the pavement at 14:40:08 and within 30 seconds hit the four civilian victims and crashed into railings at the perimeter gates of the Palace of Westminster.
Mr Cochran acted with 'instinctive courage' when he pushed his wife out of the path of the hired Hyundai Tuscon driven by Masood, the court heard. He was thrown into the air and was fatally injured, dying at the scene.
Mr Rhodes was dragged 33 metres under the car, and was taken to Kings College Hospital but never regained consciousness. He died the next day from head injuries.
Mrs Frade was hit by the car from behind and thrown into a bus lane, where she was run over by a bus and died from a 'catastrophic' head injury.
Images were shown of what happened, with the court warned that they were distressing.
Miss Cristea was thrown off Westminster Bridge, falling 12.5 metres into the Thames. She was in the water for nearly nine minutes before she was recovered.
Her cause of death was multiple organ failure, head injuries and immersion.
After mowing down the pedestrians, Masood got out of his car and became involved in a violent struggle with Pc Palmer, who stumbled and fell backwards.
Pc Palmer was stabbed, but managed to escape when Masood was distracted by two other officers.
He ran a short distance but collapsed, and despite receiving first aid from the public, the police and treatment from paramedic and air ambulance crews, died at the scene.
Masood was then challenged by an armed close protection officer, who shot him three times when he failed to drop the two knives in his hands.
The coroner will examine Masood's background, police record and the fact that in 2009 and 2010 he briefly featured in MI5 investigations. Security around the Palace of Westminster and the protection of PC Palmer's body armour is also an issue.
Video evidence will include footage of Masood as he set about hiring a car, buying knives and carrying out reconnaissance as he prepared for the attack.
Various experts will be called to give evidence about the crash, police body armour, and Masood's use of anabolic steroids.
A psychologist has also been asked to prepare a 'psychological autopsy' on Masood to look at how he came to settle on his violent intentions.
The hearings, which are due to go on for up to five weeks, will be followed by a separate jury inquest for Masood.
Mother killed on the bridge 'lived and breathed' for her daughters
A mother-of-two killed in the Westminster terror attack as she walked from work on her way to pick up her children had a smile that was like the sun 'popping out from behind a cloud'.
Aysha Frade's husband John told the inquest into her death how the couple met at the gym in 1996, and described how he was immediately struck by her smile.
He said Aysha was 'relaxed, fun to be around, laughing and smiling', and greatly valued her family and close friends.
She loved her job as a PA at a school and was a devoted mother to her two daughters, the Old Bailey heard.
Mr Frade said the couple had plans for a big white wedding in 2006, but the idea was shelved when she became pregnant with their first daughter in 2005.
Keen to be married before she gave birth, the couple 'grabbed two strangers from the street' to be witnesses and were married in a 10-minute ceremony.
The inquest heard Mrs Frade 'lived and breathed for her daughters', and her husband was in awe of the balance she struck 'between tender care and discipline'.
He told the court that she was a loving daughter to her aging mother who she visited every day.
Mr Frade went on: 'The truth is that she still doesn't feel like she's gone, her love surrounds us, her aura lights up the paths of life's journey.'
He said his wife had been 'cruelly and brutally ripped away from us'.
Her sister Michelle also read an emotionally-charged statement to the hearing.
She said: 'People cannot understand how this despicable act of futile atrocity has impacted on not only her families' lives but also herself. She will never be able to smile again, see her daughters grow up.'
Mrs Grade had said she was worried about the risk of a terror attack when her job relocated near Westminster.
Her sister went on: 'Aysha and all the other victims of this tragedy are people and not just statistics or a name that will be forgotten once this inquest is over.'
