tl;dr guy drives into a New Year's Eve revelers in an F-150 on Bourbon street, simultaneously firing into the crowd. After 3 blocks of that, gets out with an assault rifle and starts exchanging fire with the cops. He's dead, reporting is sketchy atm but they're already using the phrase "terrorist attack" and reporting s/t about a "black flag" on the vehicle. No clue how reliable that is, but it's ABC.
