Raids carried out across American states following New Orleans terror attack

The FBI is carrying out multiple raids in various American states as they try to determine if the man who killed 15 people when he drove into crowds in New Orleans was working alone.

Nine News US correspondent Lauren Tomasi says it appears the former US citizen and veteran Shamsud-Din Jabbar had been radicalised in the last few years.

“He had a series of videos taken inside a car claiming to have joined ISIS,” she told 3AW Drive.
