Multiple people were shot and several "undetonated devices" were found at a Brooklyn subway station, according to the New York City Fire Department. Firefighters responded to a call for smoke at the subway station at 36th Street and 4th Avenue in Brooklyn's Sunset Park neighborhood and found shooting victims and the devices, the New York City Fire Department said in a statement. The fire department said 13 people were injured and taken to hospitals. A law enforcement official told USA TODAY five of the 13 injured had gunshot wounds. The official was not authorized to comment publicly. Eight of the injured were taken to NYU Langone Hospital – Brooklyn, and all were in stable condition, spokeswoman Lacy Scarmana said. New York-Presbyterian Brooklyn Hospital said three patients injured in the attack were being treated, but no information on their medical conditions was immediately available. A New York City Police Department spokesperson told USA TODAY officers were investigating reports of shots fired. The police department said in a tweet, "there are NO active explosive devices at this time" and advised residents to stay clear of the area. Photos on social media appeared to show multiple people bleeding on a smoky subway platform shortly after reports of the shooting. The New York Times and Associated Press reported a person with a construction vest and gas mask was being sought.
