BOSTON (AP) — Boston firefighters have rescued three workers who were struck by falling metal support rods at a building site about 200 feet below ground.

Fire officials said Friday afternoon none of the injuries appear to be life-threatening.

Deputy Fire Chief Robert Calobrisi said rescuers were called at about 1:45 p.m. after some rebar poles fell, briefly pinning two of the workers. Firefighters used a cage similar to a portable elevator to remove the injured workers one-by-one.

Calobrisi said the men appeared to have leg and arm injuries.

They were taken to a hospital by ambulance.

The cause of the accident is still under investigation.

The site is at 50 Northern Avenue near the South Boston federal courthouse.
