The victims were taken to two hospitals in the city. Those injured were nine firefighters, two police officers, four Columbia Gas workers, two civilians and another city employee.
Springfield, which is 90 miles west of Boston and has about 150,000 residents, is the largest city in western Massachusetts. It's known as the home of the Basketball Hall of Fame, which is not near the blast site.
The city has been rebuilding from damage caused by a tornado in June 2011.
