Seven firefighters were injured, including some with serious burns, after a trash fire spread to several cars, leading to a massive explosion in the Bronx on Wednesday, according to officials.

The FDNY says firefighters responded to a call of reported car explosion around 7 p.m. at 955 Westchester Ave. in the Longwood section.

Officials say garbage and debris were on fire on the sidewalk. The flames spread to a couple of cars before the large explosion occurred.

People watched from their windows as the fire burned on the street below. Suddenly, a ball of fire was right outside their window.

“I’m like, how am I going to get out? That’s what I thought,” said eyewitness, Liza Almonte. “Like what now?”

Almonte works with children who have autism inside a building near Fox Street and Westchester Avenue when she saw garbage, debris and cars on fire, and firefighters rushing to put it out.

Their job took a dangerous turn as an explosion rocked the neighborhood.
