BOSTON - Police searched an apartment in the Boston suburb of Revere Monday night in connection with the deadly Boston Marathon bombings investigation, WBZ-TV reported.
Massachusetts State Police confirmed that a search warrant related to the investigation into the explosions was served Monday night in Revere but provided no further details, The Associated Press reported.
The FBI is now leading the investigation into the pair of horrific explosions near the finish line of the Boston Marathon that killed at least three people, including an 8-year-old child. The special agent in charge said his team will lead a coalition of federal, state and local authorities as they work on what he called a "potential terrorist investigation."
130 people were injured in the twin explosions, AP reports.
"All of a sudden, it made a really bad explosion, like a boom," said Junko Kazukawa, a runner from Denver who had just left the medical tent when the explosion occurred.
"We've had a horrific attack here in Boston this afternoon," Massachusetts Governor Deval Patrick said.
The injuries ranged from cuts and bruises to amputations. Many victims suffered lower leg injuries and shrapnel wounds. Some suffered ruptured eardrums.
Dr. Richard Wolfe, chief of the department of emergency medicine at Beth Israel Deaconess Medical Center, says one or two of the hospital's 21 patients faced a "high probability of mortality."
The finish line of the race is in an area called Copley Square. That area was evacuated after the twin detonations.
Additionally, The Associated Press reports two other explosive devices were found in the marathon area.
"People should be calm but they should understand that this an ongoing event." said Ed Davis, Boston's Police Commissioner.
Davis asked people in the city not to congregate in large crowds.
"We are stabilizing the situation at this time, but people should be cautious," Davis said, concluding the press briefing at 4:45 p.m. Eastern Time.
During that first press conference, Davis indicated a third device detonated at the JFK Library about an hour after the explosions. Later, Davis announced that was an incendiary device and not an explosive. He added that his earlier statement may have been "premature."
Almost immediately after the explosions, Sean Kelly, a reporter for ABC affiliate WCVB, tweeted about seeing victims with severed limbs being wheeled from the scene and police sprinting toward the sound of the explosions.
One of Kelly's tweets described "massive casualties." Another said storefronts were blown out at Boylston and Exeter.
"We salute all those who responded so quickly and professionally to this tragedy," President Barack Obama said in his statement from the White House, about four hours after the explosions.
The president also promised, "Make no mistake, we will get to the bottom of this."
According to the race's website, 521 Colorado residents were registered to race Monday. As of this posting, there is no information indicating any of them were injured in the explosions.
Lucy West, a runner in the marathon from Broomfield, told 7NEWS she was about a half mile from the finish when the blasts occurred. She borrowed a stranger's cellphone to tell her husband she was unhurt.
"I couldn't believe it," West said. "The police were directing us off the course."
The explosions took place about three hours after the winners crossed the finish line. The second detonation was heard a few seconds after the first one.
One woman says she was waiting for her husband to cross the finish line, and, in her words, "it just blew." She described it as "a loud boom, and then glass everywhere."
Cherie Falgoust says something hit her head, and she "just ducked."
A runner, Laura McLean of Toronto, says she heard two explosions outside the medical tent. She says, "There are people who are really, really bloody." McLean says, "they were pulling them into the medical tent."
Affiliate video feeds have shown several injured people being rushed out of the area in wheelchairs. Many showed obvious signs of bloody injuries.
Massachusetts' Emergency Management Agency had suggested people concerned about loved ones try using text messages instead of phone calls if they can't get through. They say the text messages may have better luck because they require less bandwidth.
The Massachusetts Bay Transportation Authority says all B- and C-Line service has been temporarily suspended.
Boston's police force was put onto a system of 12-hour shifts and all scheduled days off were cancelled.
The Federal Aviation Administration is warning pilots that it has created a no-fly zone over the site of two explosions at the annual Boston marathon.
The agency said in a notice issued Monday about an hour after the explosions that a no-fly zone with a 3.5-mile radius has been created over 811 Boylston Street. The zone is limited to flights under 3,000 feet in altitude, which is lower than most airliners would fly except when taking off or landing.
The notice says the no-fly zone is effective immediately, and will remain in effect until further notice. Pilots planning flights were urged to call their local flight service station.
The White House says the administration is in contact with state and local authorities and has directed federal resources to provide whatever assistance is necessary in the investigation and response.
Vice President Joe Biden was on a conference call with gun control activists when staffers turned on televisions in his office Monday to view coverage of the explosions. Biden said during the call that his prayers were with those who suffered injuries.
