New York CNN  — 

Passengers on a Manhattan-bound train had to dodge bullets while being blinded by smoke during the Tuesday morning commute, setting off a manhunt for a gunman whose motives are still unknown.

Commuters were riding the subway as it neared the 36th Street subway station in Brooklyn’s Sunset Park just before 8:30 a.m. when the gunman opened two smoke grenades, brandished a 9 mm handgun and fired at least 33 times striking 10 people – seven men and three women – according to NYPD Chief of Detectives James W. Essig.

Those 10 people were moved to area hospitals. An additional 13 people were injured via smoke inhalation, falling down or panic attacks, Essig said. Hospital representatives told CNN Tuesday’s shooting left at least 29 people injured, who were treated at three nearby hospitals for injuries, none of which are life-threatening.

“We saw a quiet Tuesday morning turn an N train into a war zone as a smoke bomb was detonated, and multiple shots rang out,” New York City Mayor Eric Adams said, adding the quick response from MTA, passengers and first responders saved lives.
