Witnesses described terrifying scenes of "insanity" that they likened to being in a "war zone" after Wednesday's early morning vehicle-ramming attack in the US city of New Orleans that killed at least 10 people.
Zion Parsons, 18, told broadcaster CNN he had gone to the city's historic French Quarter to celebrate New Year's Eve, and was now desperately trying to reach a friend who was seriously wounded in the attack.
