Police shot dead a man who rammed a pickup truck into crowds of New Year’s revellers on Bourbon Street in New Orleans, killing at least 14 people. The perpetrator was an American and former army worker who supported Islamic State. The police think he may have had accomplices. Potential explosive devices were found near the scene. The authorities are investigating any possible connection to the explosion of a Tesla Cybertruck outside the Trump hotel in Las Vegas, in which the vehicle’s driver was killed.
