16 hospitalised in New Orleans playground shooting

The identity or the motive of the shooters could not be ascertained.

New Orleans Police Department spokesman Tyler Gamble said that the account of the witnesses had led the police to believe "that there were two groups of people shooting at each other".

Mr Gamble further said that it was too soon to say if a gang activity was involved.

The police spoke to a number of witnesses; some claimed that they saw "a man run with gun with an extended clip while another gunman was still shooting into crowd".

Witness Cherie Brown said she heard "around 100" shots fired.

Three other witnesses said they saw "a man with a machine gun, and also heard more gunshots coming from within the crowd".

The shooting's aftermath was "chaotic," as reported by the Times-Picayune with many people "lying around the park's main building and hats and possessions scattered around the playground."

Several ambulances were seen at the scene, which was later cordoned off by police.

After shooting, the police immediately began sealing off the area in the attempt that the suspects could be found at the earliest.

Two blocks away from where the shooting took place, New Orleans' famous second line parade was taking place.

These parades are traditional New Orleans parades with "festive brass band processions characterized by raucous music, exuberant dancing".

Previously, in 2013, violence had errupted when gang members had fired on "a second line parade in the Seventh Ward" which had injured 19 people including two 10-year-olds.
