American tourist Kurt Cochran has been named as one of those killed in the terror attack in London on Wednesday.
Cochran, a 54-year-old engineer who also owned his own music studio in Utah, was on vacation in the city with his wife Melissa.
Mrs Cochran, 46, suffered a broken leg and rib and head injuries but it is not said to be critical.
It is believed they were two of the first people to be mowed down by the 4×4 vehicle on Westminster Bridge.
The vehicle had been hired through Enterprise Car Rental by the attacker, who has now been identified as Khalid Masood, aged 52.
A 43-year-old teacher and mother, Aysha Frade, 75-year-old Leslie Rhodes from Streatham in south London, and unarmed policeman, Keith Palmer, 48, were also killed.
Police have now confirmed that 50 people were injured in the attack and two remain in a critical condition.
The attacker, born in Kent, south of London, but believed to have been most recently living in the West Midlands, was shot dead by police outside the Houses of Parliament.
Many people gathered for a vigil in Trafalgar Square last night to pay their respects to the victims.
