Firefighters scream for an ambulance as they push an injured firefighter on a stretcher.

A fire driven by strong winds raced through a Boston brownstone on Wednesday, trapping and killing two firefighters in the basement, where their colleagues could not rescue them.

Thirteen other firefighters were injured in the blaze, and several police officers also were taken to hospitals. Some residents had to be rescued from the upper floors of the four-story apartment building, but none was hurt, city officials said.

“Today’s a sad day for the city of Boston,” Mayor Marty Walsh said. “We lost two heroes here today.”

The firefighters were identified as Lt. Edward Walsh, 43, and firefighter Michael Kennedy, a 33-year-old Marine Corps combat veteran.
