The deadly bombing at the Boston Marathon that killed at least two and injured more than 80 is believed to be an act of terrorism, senior White House officials told Fox News.
Two explosions tore through the finish line of the world-famous race just before 3 p.m., going off simultaneously as throngs of onlookers watched runners complete the 26.2-mile trek. The timing of the blasts immediately sparked suspicions of a deliberate act.
“When multiple devices go off, that’s an act of terrorism,” a senior administration official told Fox News, just moments after President Obama delivered a statement to the nation and did not use the word “terror.”
The official stressed that with details still coming in, it is unclear whether a foreign entity like Al Qaeda was behind it or whether it was home-grown terrorism. As a result, this official said the administration did not want the president to get out too far ahead and directly call it “terror.”
In addition to the deaths, some 80 people were injured – including up to 10 with amputated limbs. Authorities were guarding a person of interest at a local hospital, according to a New York Post report confirmed by Fox News. The person, who sources said was 20 years old, had severe burns, but authorities had not determined whether the person was a victim or a perpetrator. Boston Police Commissioner Edward Davis said during a press conference that no suspect is in custody. The first two explosions occurred at 2:50 p.m. – nearly five hours after the marathon began – about 50 to 100 yards apart, according to Davis. A third explosion occurred near the John F. Kennedy Presidential Library and Museum in the Columbia Point section of Dorchester, several miles southeast of the marathon's finish line, at around 4:15 p.m. Police could not say if it was related to the earlier explosions.
The horror unfolded as the city marked the 238th annual Patriot's Day, commemorating the anniversary of the Battles of Lexington and Concord at the beginning of the Revolutionary War. Competitors and race organizers were crying as they fled the bloody chaos, while some witnesses reported seeing victims with lost limbs.
"Somebody's leg flew by my head," a spectator, who gave his name as John Ross, told the Boston Herald. “I gave my belt to stop the blood.”
The FBI, which was treating the bombing as a terrorist investigation, was analyzing video from several area surveillance cameras.
Twenty-six people were transported to Brigham and Women's Hospital, including a 3-year-old, who was then taken to a children's hospital. A doctor at the hospital said at least two of the patients there are in critical condition and that some have burns and injuries that will likely require amputations.
Witnesses heard booms that sounded like two claps of thunder near the finish line inside the Fairmount Copley Plaza Hotel, according to multiple local reports. Video of the scene showed a number of emergency crews in the area tending to victims and blood on the ground near the finish line.
"I saw two explosions. The first one was beyond the finish line. I heard a loud bang and I saw smoke rising," Boston Herald reporter Chris Cassidy, who was running in the marathon, told the newspaper. "I kept running and I heard behind me a loud bang. It looked like it was in a trash can or something...There are people who have been hit with debris, people with bloody foreheads.”
"There are a lot of people down," said one man, whose bib No. 17528 identified him as Frank Deruyter of North Carolina. He was not injured, but marathon workers were carrying one woman, who did not appear to be a runner, to the medical area as blood gushed from her leg. A Boston police officer was wheeled from the course with a leg injury that was bleeding.
About three hours after the winners crossed the line, there was a loud explosion on the north side of Boylston Street, just before the photo bridge that marks the finish line. Another thunderous explosion could be heard a few seconds later.
Runner Laura McLean of Toronto said she heard two explosions outside the medical tent.
"There are people who are really, really bloody," McLean said. "They were pulling them into the medical tent."
Cherie Falgoust was waiting for her husband, who was running the race. "I was expecting my husband any minute," she said. "I don't know what this building is ... it just blew. Just a big bomb, a loud boom, and then glass everywhere. Something hit my head. I don't know what it was. I just ducked."
While the White House does in fact believe terrorism was at play, lawmakers were increasingly reaching the same conclusion.
Sen. Dianne Feinstein, D-Calif., chairwoman of the Senate Intelligence Committee, reportedly said her understanding it “that it’s a terrorist incident.”
Sen. Saxby Chambliss, R-Ga., top Republican on that committee, also said that “as the evidence mounts that this was a terrorist attack, our intelligence and law enforcement agencies must do whatever is necessary to find and interrogate those responsible so we can prevent similar attacks."
Authorities in New York, meanwhile, are deploying counter-terrorism vehicles around landmark sites in Manhattan, including prominent hotels, according to the New York City Police Department.
Nearly 25,000 people, including runners from around the world, competed in Boston's celebrated 26.2-mile race, attracting huge throngs of onlookers, especially near the finish line.
"This is a horrific day in Boston," Massachusetts Gov. Deval Patrick said in a statement. "My thoughts and prayers are with those who have been injured. I have been in touch with the President, Mayor [Thomas] Menino and our public safety leaders. Our focus is on making sure that the area around Copley Square is safe and secured. I am asking everyone to stay away from Copley Square and let the first responders do their jobs."
