(CNN) -- At least 12 people were severely injured when a pickup truck plowed into a crowd Saturday night at a Mardi Gras parade in New Orleans, New Orleans Police Department spokesman Michael Tidwell said.
There were no known fatalities, a source with direct knowledge of the incident told CNN.
The source said, "It appears to be a drunk driver," and added there were no preliminary indications that it was a terrorism-related incident.
The incident occurred near the intersection of Orleans and Carrollton Avenues where the Krewe of Endymion parade was underway
Video from CNN affiliate WDSU showed a gray pickup truck that had run into a dump truck near the intersection.
Witnesses told the station that the pickup came down one of the streets and struck several cars before hitting people in the crowd watching the parade.
"I saw the gray truck flying down Carrollton Avenue," a female witness told WDSU. "He sped up and he lost control and you could see was getting ready to turn and I knew he was going to run into all those people."
