The celebratory atmosphere of Bourbon Street in New Orleans, long an American byword for indulgence and revelry, was dimmed Wednesday as residents and visitors alike reeled from a deadly truck attack on New Year's crowds.
Several square blocks of the main entertainment district were blocked off after the attack, in which authorities said a US military veteran plowed a pickup truck into pedestrians, killing at least 15 people and leaving a tear in the heart of the city known as the Big Easy.
