The fire began in the basement and climbed up the four-story building, the Boston Fire Department said on its Twitter page.

It posted images of the blaze, showing firefighters attending to someone on a stretcher.

The area is west of downtown Boston, near the Charles River. Video showed smoke rising over the city.

On its Twitter page, Boston Emergency Medical Services said that it had transported 10 patients to area hospitals.

Three firefighters were injured, one seriously, Boston Fire Department spokesman Steve MacDonald told reporters. He said that more than 150 firefighters and between 20-30 trucks responded to the incident.

Fire officials are conducing a roll call to make sure everyone is accounted for, the spokesman said. The cause of the blaze was not immediately clear.

Mark Bristol, an eyewitness, told CNN affiliate WCVB, that he saw people climbing down the building’s fire escape.

“I watched it go from pretty small to really, really big — like there was just smoke absolutely pouring out the front entrance,” he said.
