April 15, 2013 — -- The death toll in the Boston Marathon bombings has increased to three people, according to the Boston Police commissioner.

Among the dead was an 8-year-old boy, law enforcement sources told ABC News.

"This cowardly act will not be taken within stride," Boston Police Commissioner Ed Davis said this evening. "We will turn every rock over to find the people who are responsible for this."

At least 133 people were injured, including several children with severe trauma, when bombs exploded almost simultaneously near the marathon finish line, police said.

Doctors at two Massachusetts hospitals said some of the victims underwent amputations and were suffering from burns, while others had sustained injuries from shrapnel to their lower extremities.

"Everything we saw was ordinary material that could have been propelled by the device," said Dr. Ron Walls, chair of emergency medicine at Brigham and Women's Hospital.

FBI Taking Charge of Investigation

The FBI has taken the lead in the investigation and at a news conference tonight said there are no suspects in custody.

Despite reports of law enforcement officials questioning a potential person of interest at Brigham and Women's Hospital, where many of the injured were taken, Davis urged caution.

"There's no suspect at Brigham and Women's Hospital," Davis said. "There are people we are talking to, but no suspect."

ABC News can confirm that one of the people law enforcement officials are talking to is a 20-year-old Saudi national at a Boston hospital. Sources tell ABC News that he is here legally on a student visa and that his visa is clean with no apparent criminal history.

Boston police tonight, at a news conference, said that there are people they are talking to, but no suspects.

Two bombs exploded near the race finish line on Boylston Street shortly before 3 p.m. The area was crowded with runners and spectators, and thousands of runners were still completing the race.

Davis declined to say whether he thought the devices were acts of terrorism, but said, "You can reach your own conclusion based on what happened."

According to law enforcement sources, the first bomb exploded at the Marathon Sports running store and blew out windows in four nearby buildings, injuring 15 to 20 individuals. The second blast occurred about 50 to 100 yards away, severely injuring more bystanders, Davis said.

The working theory about the bombs among Massachusetts law enforcement is that they were small, crudely made devices hidden in bags or backpacks, planted either during the race or immediately prior and detonated remotely, possibly with a cellphone. Officials have subpoenaed cellphone records.

More than 400 National Guardsmen in attendance at the marathon helped secure a perimeter around the scene.

One witness described the scene as being like a "war zone," while a doctor who was standing nearby said he immediately started treating people with severe leg injuries.

"Six or so people went down right away on my left, mostly with leg injuries. One gentleman had both legs below the knee blown off," Dr. Allan Panter, a physician who witnessed the event, told ABC News. "One girl I treated, I could not find any obvious injury to her torso, but she arrested. She was between 24 and 30.

"The people had singed facial hair and stuff. Most of the injuries were on their legs," Panter said. "I was 20 feet away, one storefront down. My ears were ringing. Everything blew out from the storefront."

Police initially said a third explosion occurred at John F. Kennedy Library in Boston, but later said it was related to a fire. No one was injured at the library, police said.

The Federal Aviation Administration issued a temporary flight restriction over the area of the explosion.

Police were asking for all video footage of the finish line at the time of the explosion.
