A powerful natural gas explosion that neighbors said felt like an earthquake rocked a busy Portland, Oregon, shopping district on Wednesday, injuring eight people.
Three firefighters, three civilians and two police officers were hurt in the blast Wednesday that utility officials say happened after a construction crew hit a gas line, officials said.
Portland Fire & Rescue Lt. Rich Chapman said none of the injuries are life-threatening. He said two firefighters suffered broken legs and one of them will require surgery. There were no reports of fatalities.
A spokeswoman for NW Natural said structural engineers were requested to assess the building's integrity after a construction crew had hit a gas line.

At least two or three surrounding buildings were damaged by the blast.
A reporter from NBC affiliate KGW-TV at the scene said he saw an injured firefighter with blood on his face. People living in the neighborhood said buildings shook from the blast.
