A US army veteran loyal to the Islamic State jihadist group likely acted alone when he killed 14 and injured dozens in a truck attack on a crowd of New Year revelers in New Orleans, the FBI said Thursday.

Despite initial concerns that Shamsud-Din Jabbar, 42, had accomplices still on the run, preliminary investigations show he likely acted alone, FBI deputy assistant director Christopher Raia said.
