One person is dead and 11 others injured in a shooting in the New York City borough of Brooklyn on Saturday night, according to the New York Police Department (NYPD).
The incident took place during a large outdoor event at a local park at around 11 p.m. (0300 GMT on Sunday).
A 38-year-old man died upon arrival at hospital while several others remained in critical condition, an NYPD spokesman was cited by the local media as saying early Sunday.
No arrest has been made by police.
According to NYPD Commissioner James O'Neill, there were around 2,000 to 3,000 people attending the annual Old Timers Event when the shooting occurred.
New York Mayor Bill de Blasio said on Sunday that the shooting "shattered a peaceful neighborhood event."
"We will do everything in our power to keep this community safe and get guns off our streets," he tweeted.
The United States has one of the highest gun-related death tolls in the world due to lax gun control laws, according to a study released in August last year by the Institute for Health Metrics and Evaluation at the University of Washington.
