BREAKING: FBI Houston ‘conducting law enforcement activity’ in connection with New Orleans terror attack

They say that the agency has "secured a perimeter in that area and are asking people to avoid the area. FBI Houston personnel and specialized teams will be on-site for several hours. This activity is related to this morning's New Orleans attack, but due to the ongoing nature of the investigation, no further information can be provided."

FBI agents in New Orleans on Wednesday gave a briefing in which they said that they were looking for additional suspects who they believe worked with the now-deceased driver of the white pickup truck that plowed into a crowd of New Year's revelers in the early morning hours of the New Year. It was further disclosed that three men and one woman were seen placing explosive devices around the French Quarter in advance of the truck massacre.

The suspect in that attack, who was killed in a shootout with police, hailed from Houston, Tex. A US citizen, Shamsud-Din Jabbar, was a member of the US Army and was honorably disharged. He was a seller of weapons online and is believed to have been in possession of firearms that had been stolen in New Jersey, a glock pistol and a .308 rifle among them. The FBI said that Jabbar had an ISIS flag in the truck.

Jabbar rented the electric Ford F-150 using carshare app Tora in Houston. He drove it into the crowd at 3:15 am local time. Ten were killed in that attack, 35 injured persons were taken to local hospitals. The first known victims of the attack include 18-year-old Nikyra Cheyenne Dedeaux, of Gulfport, Miss., 37-year-old Reggie Hunter, a father of two from Baton Rouge, and 27-year-old Tiger Bech, of Lafayette, who died in hospital.

Jabbar was shot and killed by law enforcement officers during a gun fight that ensued when he exited the vehicle and began firing.

This is a developing story.
