EWING, N.J. (AP) _ A hospital says it is receiving at least six patients from an explosion at a townhouse complex in a suburb of New Jersey's capital city that caused heavy damage.
A spokesman at Capital Regional Medical Center says two of the injured apparently have traumatic injuries.
Television footage shows damage to several units at the development in Ewing, outside Trenton, and widely scattered debris.
Flames can be seen shooting up from the ground, apparently fed by a gas line.
People in the area report having heard a loud boom.
Annette Hicks, a spokeswoman for PSE&G utility, says the company is investigating at the site of the explosion and couldn't comment yet on a possible cause or whether workers were injured.
A police dispatcher in Ewing says he has no information on a cause.
