The British Foreign Office has confirmed that a British national was among at least 14 people killed in the car attack in New Orleans on New Year's Day.
The Metropolitan Police named him as Edward Pettyfer, 31, from Chelsea, London.
The Foreign, Commonwealth and Development Office said in a statement that it was supporting the victim's family.
During the attack, a man drove a pickup truck into crowds on Bourbon Street in the city before he was killed by police.
The New Orleans coroner gave the preliminary cause of Mr. Pettyfer's death as “blunt force injuries” sustained on Bourbon Street, the PA reports.
“The entire family is devastated by the tragic news of Ed's passing in New Orleans. He was a wonderful son, brother, grandson, nephew and friend to many,” the Pettyfer family said in a statement.
“We will all miss him terribly. Our thoughts are with the other families who have lost loved ones due to this horrific attack. We ask that we mourn Ed's loss as a family in private. Thank you.”
A famous American college football player and an ambitious young nurse The victims also included the mother of a four-year-old child.
Their names were revealed by their families and relatives before the authorities in the United States completed post-mortem examinations.
The attack is believed to have been carried out by a 42-year-old Texas resident and US Army veteran.
After driving the truck through the crowds, the suspect reportedly got out and fired a weapon before police shot him dead.
The FBI says an ISIS flag was found inside the car.
Two explosive devices were also found nearby, according to police.
The suspect is called Shams al-Din Jabbar It is believed that he acted alone The FBI said it was a “vicious and deliberate act.”
At least 39 other people were injured during the attack in the city's French Quarter – a bustling nightclub frequented by locals and tourists – at around 03:15 (09:15 GMT) on Wednesday.
Some of the injured have been discharged from hospital, but more than a dozen remain, and some are receiving treatment in the intensive care unit.
Bourbon Street opened to the public Thursday morning ahead of the Sugar Bowl, a much-anticipated college football game between Notre Dame and the University of Georgia, which attracts thousands of attendees.
