A former employee of a New York City hospital opened fire with an assault rifle inside the building, killing one doctor and wounding six other people before fatally shooting himself, officials said.
The gunfire broke out at 2:50 pm local time on Friday (18:50 GMT) inside the Bronx Lebanon Hospital in the Bronx.
The assailant, wearing a white lab coat and armed with an assault rifle, stalked the 16th and 17th floors of the Bronx-Lebanon Hospital Center.
Police who swarmed the building found him dead of a self-inflicted gunshot wound after a search, they said.
One physician was shot to death in the course of the bloodshed, and six other people were injured, five seriously, including one who suffered a gunshot wound to the leg, Police Commissioner James O’Neill said at a news conference.
“One doctor is dead and there are several others who are fighting for their lives right now,” New York Mayor Bill de Blasio told reporters.
The mayor characterised the shooting as an “isolated incident” that appeared to be “workplace-related”.
Authorities did not immediately identify the gunman or any of his victims.
An NYPD official also confirmed on Twitter that the attacker died in hospital.

Television images showed the hospital surrounded by police cars and fire trucks. Police could be seen on the roof of the building, at one point, with their guns drawn.
Bronx Lebanon Hospital describes itself as the largest voluntary, not-for-profit health care system in the south and central Bronx.
The 120-year-old hospital claims nearly 1,000 beds spread across multiple units.
