A vehicle has driven into a crowd at a Mardi Gras parade in the US city of New Orleans, leaving 28 people injured, some seriously.
It hit crowds watching the Krewe of Endymion parade in the Mid-City district early on Saturday evening.
One person was in custody on suspicion of driving while intoxicated, police said, and terrorism was not suspected.
The driver of a silver truck seemed unaware of what he had done, one eyewitness told local media.
"He was just kind of out of it,'' Kourtney McKinnis told the New Orleans Advocate.
