One day after a man drove a truck into New Year's revelers on Bourbon Street, the FBI says he likely did not have accomplices.

The FBI now says that the pickup truck driver responsible for a deadly rampage in New Orleans acted alone. Officials said Wednesday that they were seeking additional potential suspects in an attack being investigated as an act of terrorism.

The investigation into the truck attack on New Orleans' Bourbon Street continued Thursday. The FBI said the attacker posted videos declaring his support for ISIS shortly before the deadly rampage.

Shamsud-Din Jabbar, who drove a pickup truck into a crowd on Bourbon Street, killing 14 people, posted 5 videos on Facebook hours before the attack.

The ISIS-inspired terrorist who mowed down a crowd of New Year’s Eve revelers on Bourbon Street drove from Houston to New Orleans recording deranged Facebook videos confessing his thirst to kill and pledging allegiance to the Islamic terror group.

New Orleans attacker Shamsud-Din Jabbar joined Isis last summer and planned to harm his own family, the FBI today revealed. Speaking at a press conference today (2 January) law enforcement officials said they believe Jabbar is solely responsible for the deadly New Year’s Day attack in New Orleans.
