At least 13 people were shot or otherwise hit by shrapnel at multiple subway stations along the northbound N train line in Brooklyn Tuesday morning.

Now, a manhunt is underway for a gunman described as wearing a gas mask and an orange construction vest. No motive for his actions has yet been identified.

According to local media, shots were fired at the 36th Street station in Sunset Park around 0830 local times (1330 GMT) on Tuesday morning.

Photos from the scene show bloodied passengers lying on the station floor. Undetonated explosive devices were also found on the scene.

Some of the wounded passengers made their escape by jumping on a train, the sources said.

A spokesman for New York City Mayor Eric Adams called on New Yorkers "to stay away from this area for their safety and so that first responders can help those in need and investigate".
