Ambulances took 10 people to hospital, Tyler Gamble said, and others were taken by private vehicles.

It is yet not known what started the shooting or how severe the injuries are.

According to Tyler Gamble, there were two groups at the park – one had walked there as part of a neighborhood parade, while others were watching or participating in a video being made in the park.

Witnesses told local TV station WWL that there were about 500 people at the park and that two gunmen opened fire in the crowd.
