Washington | The deadly New Year’s Day attack in New Orleans by a man driving a pick-up truck and an electric vehicle explosion in Las Vegas the same day have prompted law enforcement officials nationwide to increase security, issue fresh safety warnings and reassess preparations ahead of events that could be targeted for violence.

The FBI, Department of Homeland Security and the US National Counterterrorism Centre at the weekend warned about possible copycat attacks in a security bulletin after an Army veteran from Texas rammed a truck into New Year’s revellers last Wednesday, killing at least 14 people on Bourbon Street in New Orleans.
