A British national was among at least 14 people killed in the vehicle attack in New Orleans on New Year’s Day, the Foreign Office has confirmed.
He was named by the Metropolitan Police as Edward Pettifer, 31, from Chelsea, London.
In a statement, the Foreign Commonwealth and Development Office said it was supporting the victim’s family.
During the attack, a man in a pickup truck drove through a crowd on Bourbon Street before being killed by police.
The New Orleans coroner gave Mr. Pettifer’s preliminary cause of death as “blunt force injuries” suffered on Bourbon Street, the AP reports.
In a statement, Mr. Pettifer’s family said: “The entire family is devastated by the tragic news of Ed’s death in New Orleans. He was a wonderful son, brother, grandson, nephew and a friend to so many.
“We will all miss him terribly. Our thoughts are with the other families who have lost family members to this terrible attack. We ask that we can mourn Ed’s loss as a family in private. Thank you.”
A famous American college football player, a young aspiring nurse and a mother of a four-year-old child was also among the victims.
Their names were released by families and relatives before US authorities completed the autopsies.
The attack was allegedly carried out by a 42-year-old Texas resident and U.S. Army veteran.
After driving the truck through the crowd, the suspect allegedly got out and fired a gun before being shot and killed by police.
The FBI says an Islamic State group flag was found inside the vehicle.
Two improvised explosive devices were also discovered nearby, according to police.
The suspect, named Shamsud-Din Jabbar, he is believed to have acted alone in a “premeditated and evil act,” the FBI said.
At least 39 other people were injured in the attack, which took place around 3:15 a.m. (0915 GMT) on Wednesday in the city’s French Quarter, a lively nightspot popular with locals and tourists.
Some of the injured have been released from hospital, but more than a dozen remain, some being treated in intensive care.
Bourbon Street opened to the public Thursday morning ahead of the Sugar Bowl, a highly anticipated college football game between Notre Dame and the University of Georgia that draws thousands of attendees.
