Six people died when a home in Brooklyn caught fire early Thursday. 

Firefighters received calls about a large fire in a two-story home in Sunset Park, and they arrived on the scene around 2 a.m., the New York Times reported. 

More than 230 emergency workers responded to the call, which is the deadliest fire in New York City this year, the Fire Department said. 

Four victims were pronounced dead at the scene, and two others later died at the hospital. Two others injured in the incident remain at the hospital, fire officials said. 

The cause of the blaze is under investigation.
