WILLIAMSBURG - Two people were killed and dozens displaced by a massive early morning fire at an apartment building in Williamsburg Monday, police say.

The fire gutted a three-story apartment building at the corner of Richardson and Lorimer streets around 1:30 a.m., according to police.

Two of the nearly 200 firefighters who responded were injured in the blaze, according to officials. Both are expected to be OK.

Officials say EMTs discovered a body after searching the building. Several hours later, they say they recovered a second body.

Officials say the cause of the fire is still under investigation, but it may have sparked beneath a kitchen floorboard on the left side of the building. 

Residents say they heard a loud explosion moments before the building erupted in flames and smoke filled the hallways.
