Dozens of people, including 33 New York firefighters, were injured in a six-alarm blaze that erupted in the Bronx overnight, sending scores of families into the streets.

The fire broke out shortly after midnight at a six-story building less than a mile from Yankee Stadium with about 600 residents.

Three residents suffered injuries along with the firefighters. The FDNY said most of the injuries were related to heat exposure or were scrapes or bruises; all are believed to be minor. One captain said he experienced chest pain.

More than 200 firefighters battled the blaze during the hot and humid night. The fire chief said it began in a sixth-floor apartment in the back of the building and spread to three other units. One wall partially collapsed and flames could be seen leaping from the roof before firefighters contained it around 5 a.m.

Due to several hot spots that remained early Wednesday, fire officials cautioned that the fire is still active.

It wasn’t immediately known how many people were inside the building when the fire started, but fire officials said everyone has been accounted for.

The cause of the fire is under investigation. The Office of Emergency Management said 66 units were damaged by the inferno.

The Red Cross is assisting residents who might need emergency shelter or food. Forty families already have registered with the organization.
