One person was injured in a fire that shot through the roof of a building in the North End late last night.
The blaze, which reached four alarms and sent scores of firefighters racing to the North End, broke out just after 11 p.m. at 26 Cooper St., according to the fire department.
Flames were shooting out windows when firefighters arrived, forcing them to make a fast and aggressive attack to keep the flames from spreading to other buildings in the dense neighborhood.
One person was taken to Massachusetts General Hospital with burns.
Thirteen people were displaced from 26 and 28 Cooper St. and 29 North Margin St., fire official said. The Red Cross and city's neighborhood services were helping those who were displaced.
A fire official estimated that the blaze caused $1 million in damage.
The cause is being investigated.
