A U.S. Army veteran with an Islamic State (IS) group flag on his truck swerved around makeshift barriers and plowed into New Orleans¡¯ crowded French Quarter on New Year¡¯s Day, killing 15 people in an attack officials believe was carried out with the help of others.

The suspect, identified as Shamsud-Din Jabbar, 42, a U.S. citizen from Texas who once served in Afghanistan, was killed in a shootout with police after ramming the crowd.

The attack, which injured 30 other people, took place around 3:15 a.m. (0915 GMT) near the intersection of Canal and Bourbon Streets, a historic tourist destination known for its music and bars where crowds were celebrating the new year.
