Three people are dead and six injured, including three firefighters, from two separate blazes in Brooklyn and the Bronx last night and this morning. Two brothers were found dead inside a sixth floor apartment at 2700 Grand Concourse in the Bronx, where 70 firefighters responded to a blaze at approximately 10:30 p.m. "Heavy flames spewed through two windows at the building" when crews arrived, NBC New York reports, and the fire chief on the scene said, "It was a dangerous move to get in there."

One brother was found in the bedroom where the fire broke out, the other was discovered in a different part of the apartment. The brothers, both in their 40s, were pronounced dead at area hospitals. ABC 7 reports that firefighters "had a tough time getting water onto the fire and had to stretch hoses quite a distance," but the blaze was brought under control in about 30 minutes. Three firefighters sustained minor injuries.

In Kensington, Brooklyn, fire claimed the life of a 26-year-old woman on the third floor of a house at 293 East 8th Street, shortly before 5:30 a.m. The woman and her two sisters, ages 28 and 16, were hospitalized with life threatening injuries, ABC 7 reports. A fourth victim sustained minor injuries.

It took approximately 100 firefighters to bring the blaze under control. It's believed the fire started on the second floor; the sisters were found unconscious in a third floor bathroom.

The causes of both fires remain under investigation.
