A gunfire at a city park in New Orleans, U.S., ended up sending 16 people to the hospital on Sunday. According to witnesses, two gunmen opened fire at the gathering of around 500 people.

According to police spokesperson Tyler Gamble, officials rushed to the Bunny Friend park located in the 9th ward of the city on Sunday night as the shooting erupted. Local television station WWL TV reported that around 10 wounded people have been taken to the University Medical Centre hospital by ambulance, while others had to be taken by private vehicles.

According to New Orleans Police Superintendent Michael Harrison, people had gathered at the park to film a music video. Mayor Mitch Landrieu said that the Nine Times Second Line parade also took place a little earlier the same day, a few blocks away from where the shooting took place.

The shooting reportedly occurred around 7 p.m. local time. The (New Orleans) Times-Picayune reported that after the shooting, the scene appeared quite disturbing with wounded people scattered around the park’s main building while their belongings were strewn across the ground.

There is still no information on what caused the firing and how serious the injuries of the wounded are.

Landrieu previously said in January that the number of people killed in New Orleans had declined to a 43-year low since 1971, with 150 murders reported. In 2014, the city recorded the lowest count of murders in a decade. According to Times-Picayune, following the Sunday’s shootings, the murder count for the city stands at 138 in 2015.
