Firefighter Injured Battling 6-Alarm Blaze At Roxbury Church

A firefighter was injured Saturday morning battling a six-alarm fire at a Roxbury church, city fire officials said.

Authorities responded to the blaze at the Holy Mt. Zion church at 113 Harold St. at around 4 a.m., the Boston Fire Department said in a series of tweets.

The fire started in the church's basement and tore through roof, causing part of it to collapse, Boston fire said. Conditions were tough as firefighters worked in 9-degree weather.

The injured firefighter was taken to the hospital, where he was treated for a leg injury. Nobody else was injured, officials said.

Firefighters were still on scene at 10 a.m. after the fire was knocked down extinguishing hot spots, and they were expected to be on scene "for quite a while," Deputy Chief Michael Doherty said.

The building suffered a total loss and is unsalvageable, according to Doherty.

Now, the Holy Mt. Zion congregation is hoping to find a new venue for its Sunday service. As he watched firefighters douse the church with water, Reverend Eustace Osborne Jr. said he was thinking about tomorrow's sermon.

"I don't necessarily think it's going to be about this fire. Life isn't over. No one was hurt. No one was killed," he said. "Things were damaged that can always be replaced."

The cause of the fire remains under investigation, authorities said.
