US President Joe Biden has visited the scene of the New Year's Day attack in New Orleans that left 14 people dead and dozens injured when a US Army veteran drove a truck into a crowd of revellers.
Mr Biden and his wife, Jill, made a stop at Bourbon Street to pay respects to those who died there before making their way to a church for a memorial service.
The first lady laid a bouquet of flowers in front of a makeshift memorial. The president stood with his wife and crossed himself.
Shamsud-Din Jabbar, the Texas man who drove the truck and was killed in a shootout with police.
The FBI said the 42-year-old, who had pledged allegiance to the Islamic State extremist group, acted alone.
President Biden supported that conclusion in comments made on Sunday.
"I spent literally 17, 18 hours with the intelligence community from the time this happened, establishing exactly what happened.
"We established beyond any reasonable doubt that New Orleans was an act of a single man," Mr Biden said.
"He had real problems in terms of his own, I think, mental health going on, and he acted alone."
Mr Biden, like other presidents before him, has made multiple trips during his time in office to comfort communities after natural disasters or acts of violence.
His first wife and infant daughter lost their lives in a car crash, and one of his adult sons died of cancer.
"I've been there," President Biden said.
