NYC gas explosion levels 3 homes, displaces 2 families after fire spreads from vacant building

At least three New York City buildings have been or will be destroyed after a Friday morning gas explosion caused fire to roar through a Brooklyn street, leaving at least two injured and six people displaced from their homes, officials said. 

At least 106 firefighters and FDNY personnel responded to the two-alarm blaze, the department said. 

Investigators determined that the explosion – which was reportedly preceded by reports of a smell of gas – happened in a vacant home. But the blaze then spread to two other homes, which were housing two families, authorities said. Two people suffered minor injuries.
