New Orleans police said 10 people were shot early Sunday in the city's famed French Quarter.
Two of the victims were in critical condition, police said.
Police had initially said 11 were injured, but later revised it down to 10.
No arrests had been made, police said, with any motive unclear. One person was detained by police but their connection to the incident is unknown.
The shooting took place on a busy commercial block of Canal Street that has streetcar tracks and is near many hotels.
