Sixteen people were injured after a shooter wearing a gas mask opened fire in a New York City subway car Tuesday morning in an incident in which smoke also engulfed the car, authorities said.

The violence began at 8:24 a.m., when a Manhattan-bound N train was waiting to enter the station at 36th Street and 4th Avenue, in the Sunset Park section of Brooklyn, New York Police Department Commissioner Keechant Sewell said at a Tuesday press conference.

According to Sewell, the suspect donned a gas mask, then took out a canister of smoke and threw it to the ground, causing the car to begin to fill with smoke. Then, he opened fire.

According to Sewell, none of the injuries are considered life-threatening. The shooting is not being investigated as an act of terrorism at the moment, Sewell said, but the investigation remains ongoing.
