FBI says New Orleans truck attacker acted alone

The FBI has declared the perpetrator accused of a deadly New Orleans terrorist attack acted alone. Shamsud Din Jabbar drove a vehicle into a crowd on New Year's Day – killing at least 14 people and injuring 30 others. According to the FBI, he posted five videos on Facebook after joining ISIS, where he pledged allegiance to the terrorist group. The agency says there is no definitive link between that attack and a truck explosion in Las Vegas. Warning: Images shown may be distressing to some viewers.
