At least four people were shot Friday morning outside the Empire State Building in New York City, officials told NBC News, adding that there could be as many as 10 victims.
The suspected gunman was killed, officials said. Another person was reportedly dead too. It wasn't immediately clear if the gunman's wound was self-inflicted or if the suspect was shot by police.
The condition of the other victims is unknown at this time.
A law-enforcement official said the shooting did not appear to be terror-related, and may have been the actions of a disgruntled employee of a business in the Empire State Building, which houses 1,000 businesses.
"I heard pop, pop, pop, pop, and I ran back into my offices,” a witness, Gloria Walker, told NBC News. "I ran, I ran, I ran,” she said when she heard it.
The FDNY told NBC News they responded to a call about the shooting at Fifth Avenue and 34th Street at 9:07 a.m. Friday and arrived at 9:13 a.m.
More than 21,000 employees work in the building each day, making the Empire State Building the second-largest single office complex in the U.S., after the Pentagon.
In 1997, a 69-year-old man opened fire on the observation deck of the iconic landmark, killing one person and wounding six before shooting himself in the head, according to NBCNewYork.com. The gunman, Ali Abu Kamal, was taken to the hospital, where he died more than five hours after self-inflicting the fatal wound.
Law enforcement officials believe the 1997 attack was pre-meditated.
It is not clear if Friday morning's shooting was premeditated, nor was it known if the victims were targeted or shot at random.
