 Police were on their way to break up a big crowd at Bunny Friend Playground when gunfire erupted at the park in the city's 9th Ward, the police said in a statement Sunday. 
  
 Police said 10 people were taken to the hospital in ambulances while another six were taken in private vehicles. Photos of the scene showed emergency workers wheeling some of the wounded to ambulances on gurneys while other people who appeared to be in pain lay on the ground. 
  
 Joseph Jordan was inside a house across the street from the park with his friend, who gave her first name as Raven, when they heard gunshots. Later someone called Raven and told her that her niece had been shot. The two rushed to the hospital to check on the 14-year-old, who had been shot three times in the leg. 
  
 Speaking of the hospital, Jordan said: "It's still crowded back there." 
  
 Outside University Medical Center, Kawandra Hayney said she had been driving about two or three blocks from the playground with her daughter when people ran by shooting. Her 14-year-old daughter was hit once in the knee and five times in her backside. Hayney pulled her daughter out of the truck and under it to hide, then into a nearby ditch. 
  
 "I saw the police coming, and I ran over to them," she said. She said she later counted seven bullet holes in her truck. 
  
 Investigators don't know what started the shooting, police spokesman Tyler Gamble said. He said all the victims are listed in stable condition. He said the victims suffered either direct gunshot wounds or were grazed by bullets. 
  
 Large stadium lights lit up the park Sunday as police continued to work the crime scene. Witnesses told police that the gunmen ran off after the shooting was over. 
  
 As many as 500 people could have been in the park when the shooting happened, said police chief Michael Harrison. Police earlier said the people were there for an impromptu music video but Gamble later told reporters that while a video was being filmed, the event was a primarily a block party. Gamble said that neither the block party nor the music video had a permit. 
  
 Police Superintendent Michael Harrison told WDSU-TV that the shooting might have been gang-related. Police had been helping with a parade that had been taking place about a block away from the park, and were able to quickly get to the park, Harrison told the TV station. 
  
 Mayor Mitch Landrieu, speaking in a news conference aired on WWL-TV, called on people who were in the park to come forward with information. The police have also asked people who might have any video of the shooting to bring it to police. 
  
 "At the end of the day it's really hard to police against a bunch of guys who decide to pull out guns and settle their disputes with 300 people in between them. That's just not something you can tolerate in the city," Landrieu said.

  ||||| Seventeen people were injured Sunday night (Nov. 22) after gunfire erupted during a block party at Bunny Friend Park in the Upper 9th Ward, New Orleans Police Department officials said. 
  
 EMS transported 10 victims to area hospitals, and another six arrived at emergency rooms through private conveyance. Monday morning NOPD said a 17th victim had been confirmed. 
  
 Speaking at the scene Sunday night, NOPD Superintendent Michael Harrison said he believed multiple people had fired into the crowd of more than 300. NOPD spokesman Tyler Gamble later confirmed that all victims are in stable condition. 
  
 "Detectives are still working to determine the extent of all of the victims' injuries," NOPD said in a news release. "Information on the age and gender of all victims involved as well as the extent of their injuries will be provided when it is available." 
  
 Several witnesses said the gathering was part of an after party for the Nine Times Social Aide & Pleasure Club's annual second line, which earlier in the day proceeded through the Desire and Florida Development neighborhoods before disbanding at Sampson Park in St. Roch. Harrison described the after-party as an "unpermitted event." 
  
 "We staffed the second line pretty heavily," Harrison said. The NOPD later received word of an impromptu music video being shot inside the park, he said. The event must have "circulated through social media," he added, "because we got no report of it." 
  
 Officers were dispatched to the park to shut the gathering down, Harrison said. "They were a block away when they heard gunshots and were flagged down" from there. EMS appeared on the scene soon after, he said. 
  
 One witness, a nurse who declined to provide her name citing safety concerns, said two groups began shooting at each other around 6:15 p.m. "It was like New Year's Eve all over again," she said. 
  
 Multiple witnesses said they saw a man with a silver-colored machine gun fleeing the scene toward Louisa Street. They said the gunfire continued inside the park as the man ran away. 
  
 After the shooting, witnesses described several gunshot victims lying in the middle of Gallier Street and Desire Street as EMS responders administered to them. 
  
 Joseph Jordan was in a house across the street from the park with his friend, who gave her first name as Raven, when they heard gunshots. Later someone called Raven and told her that her niece had been shot. The two rushed to the hospital to check on the 14-year-old, who had been shot three times in the leg. 
  
 Speaking of the hospital, Jordan said: "It's still crowded back there." 
  
 Mayor Mitch Landrieu joined Harrison during a press conference at the scene. He applauded the quick response of the NOPD and EMS. 
  
 "At the end of the day, it's really hard to police against a bunch of guys who decided to pull out guns and settle their disputes with 300 people in between them," Landrieu said. "It's not something you can tolerate in the city." 
  
 Both Harrison and Landrieu said they hoped that witnesses inside the park would help the NOPD to identify the shooters. 
  
 "This is a classic case where we need citizen help," Harrison said. "People know who did this. We need them to come forward and tell us so we can bring these people to justice."

Output:
The "Bunny Friend Playground" might sound like one of the most harmless places on the planet, but it was the site of a shooting that left at least 16 people injured in New Orleans on Sunday evening. Police say hundreds of people were at the 9th Ward park for an unauthorized block party and music video shoot when two groups of people opened fire on each other, WDSU reports. A police spokesman says some of the injured suffered direct bullet wounds while others were grazed by bullets, the AP reports. He says all the victims are in stable condition and the cause of the incident is still unclear. Police say officers were already on their way to break up the party when the shooting began. Witnesses tell the New Orleans Times-Picayune that they saw a man with a machine gun flee the scene and gunfire continued as he made his getaway. No arrests have been made, and police have appealed for information, calling the incident a "classic case where we need citizen help." At a Sunday night press conference, Mayor Mitch Landrieu denounced the shootings and urged witnesses to come forward. "At the end of the day, it's really hard to police against a bunch of guys who decided to pull out guns and settle their disputes with 300 people in between them," he said, per the Times-Picayune. "It's not something you can tolerate in the city."
