Seven Boston area hospitals were treating at least 143 patients injured in the explosions that occurred earlier Monday at the finish line of the Boston Marathon.
At least three people had died as of Monday night, police said.
The victims' injuries included broken bones, shrapnel wounds and ruptured eardrums.
At Massachusetts General Hospital, said Alisdair Conn, chief of emergency services, said: "This is something I've never seen in my 25 years here ... this amount of carnage in the civilian population. This is what we expect from war."
- Massachusetts General Hospital received 29 patients from the blasts in its emergency room, including eight who were critically injured and five in serious condition, according to a hospital spokesman.
- Tufts Medical Center was treating 17 patients, a spokesman said.
- Brigham and Women's Hospital has 28 patients, including two who are critically injured and between eight and 10 who were in serious condition, according to a spokesman.
- Beth Israel Deaconess Medical Center was treating 21 patients, a spokeswoman said in an e-mail.
- Boston Medical Center had 23 patients, including two children. Most of the patients had lower leg injuries, a spokeswoman for the hospital said in an e-mail.
- St. Elizabeth's Medical Center in Brighton, Mass., was treating about 15 patients, according to a spokesman for Steward Health Care System, which operates St. Elizabeth's.
- A spokesman for Boston Children's Hospital said in an e-mail the hospital was treating 10 patients whose conditions ranged from good to serious.
Two bombs exploded near the finish line of the race, creating a terrifying scene of broken glass, smoke and severed limbs, authorities said.
Mass General trauma surgeon Dr. Peter Fagenholz told ABC News that the “most common serious injuries are combined lower extremity injuries” and that the hospital had performed several amputations.
A third blast rocked the John F. Kennedy Library several miles away and more than an hour later, but no injuries were reported, police said. A senior U.S. intelligence official said two other explosive devices were found near the marathon finish line.
There was no immediate word on the motive or who may have launched the attack, and authorities in Washington said there was no immediate claim of responsibility. Some 27,000 runners took part in the 26.2-mile race, one of the world's premier marathons.
The twin blasts at the race took place almost simultaneously and about 100 yards apart, tearing limbs off numerous people, knocking spectators and at least one runner off their feet, shattering windows and sending smoke rising over the street.Follow Jaimy Lee on Twitter: @MHjlee
