WASHINGTON -- The White House says President Barack Obama has been notified about the explosions at the finish line of the Boston Marathon.
The White House says the administration is in contact with state and local authorities and directed his administration 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.
"Apparently there has been a bombing," Biden said. "I don't know any of the details of what caused it, who did it. I don't think it exists yet. But our prayers are with those people in Boston who suffered injury."
Shortly after the explosions, Secret Service shut down Pennsylvania Avenue outside the White House, cordoning off the area with yellow police tape. Several Secret Service patrol cars also blocked off the entry points to the road.
The White House was not on lockdown and tourists and other onlookers were still able to be in the park across the street from the executive mansion.
One marathon suspect has been captured, according to an official with knowledge of the investigation.
Another remains on the loose in Watertown after a firefight with police. Authorities have established a 20-block perimeter as they search for him.

Just hours after the FBI released the first photos of suspects in the Boston Marathon bombing, a new photo of Suspect 2 may have emerged.
David Green, 49, of Jacksonville, Fla., had just completed his first Boston Marathon, when he snapped a picture with his iPhone 4S, taken at 2:50, just after the two blasts ripped through the finish line area, killing three people and injuring more than 180 others.
The FBI has not publicly confirmed this photo as Suspect 2, but Green told the Huffington Post that an agent told him, "this is probably the best we have right now."
The man who appears to be Suspect 2 is wearing a white hat with a "3" on the side as seen in the publicly-released photos.

Minutes before the bombs blew up in Boston, Jeff Bauman looked into the eyes of the man who tried to kill him.
Just before 3 p.m. on April 15, Bauman was waiting among the crowd for his girlfriend to cross the finish line at the Boston Marathon. A man wearing a cap, sunglasses and a black jacket over a hooded sweatshirt looked at Jeff, 27, and dropped a bag at his feet, his brother, Chris Bauman, said in an interview.

BOSTON -- Moments after the FBI revealed images of two baseball cap-wearing men wanted for questioning about the Boston bombings, the press conference descended into a sideshow.
A journalist from a far-right wing website called Info Wars shouted out a question accusing the government of carrying out the attack that killed three, and maimed or injured 170 others.
FBI Special Agent in Charge Richard Deslauriers ignored the allegation of a government conspiracy from reporter Daniel Bidondi, but the Alex Jones protege did not stop hollering.
"The FBI lies," Bidondi said. "We've got the proof," he said accusing the government of a "false flag" attack in which it staged the blasts and made them appear like the work of terrorists.
Bidondi found himself at the center of an media scrum with cameras and microphones pointed at his face after law enforcement officials left the podium in the Sheraton hotel.
Another reporter ridiculed Bidondi from across the room, telling him to shut up and calling him an asshole.
The excitement quickly dissipated as reporters returned to delivering the news about the official images of the suspects.
Bidondi has been a presence at other press conferences this week related to the bombing investigation.

Dr. Ralph Gross, a facial recognition expert at Carnegie Mellon University, said the FBI photos of two suspects in the Boston Marathon bombing are likely too grainy to be matched against a driver's license database or Facebook. But he thinks they may be just good enough for someone who knows the individuals to identify them.
"The resolution isn't particularly good. The one that's kind of best is unfortunately a side view -- and in general the face recognition software works best with frontal view," he said.
Research has consistently found, however, that people can spot people they know even in grainy, off-center photographs.
"Humans are actually very good at recognizing people that they are familiar with," Gross said. "Somebody that might know these guys, or might know the way they dress, might certainly be able to recognize them."
The FBI said the men should be considered armed and dangerous, and urged tipsters to call 1-800-CALL-FBI if they believe they have information that could lead to an arrest.
The New York Daily News reportedly doctored its front page photograph of the Boston bombings (see update below).
WARNING: LINK GOES TO GRAPHIC PHOTO
CNN reports that, because of a flood of traffic, the FBI's site is temporarily down.
FBI's Richard Richard DesLauriers said the only official photos that should be relied upon in the investigation are the pictures the FBI unveiled.

Christine Anastos and her therapy dog Windy comforted runners who dropped in to the Boston Athletic Association's offices today.
Windy, a black labrador who retired from Guiding Eyes for the Blind, was a big hit with the Marathoners.
"I don't think there was a moment when someone wasn't petting her," she said about Windy,who was joined by a Newfoundland and boxer. "All she has to do is be herself. She's so sensitive. She takes in all the emotion."
Anastos makes Windy available through Therapy Dogs International There are more than 100 therapy dogs available within a 20 mile radius of Boston, she said, so people should contact the group if they're interested.

The New York Post once again found itself in trouble after it published front-page photos of two men on Thursday who it said were being searched for in connection with the Boston bombings. The problem? They were completely innocent.
The FBI press conference scheduled for 5 p.m. today is the first public briefing in two days, according to Fox News.

FBI will most likely release photos of persons of interest in Boston bombings this afternoon - @petewilliamsnbc— NBC Nightly News (@nbcnightlynews) April 18, 2013
A local paper in Minnesota ran an unfortunately placed ad for a pressure cooker -- right next to a story about the Boston Marathon bombing, which was likely carried out using pressure cookers packed with shrapnel and explosives.
From the AP:
BOSTON -- Kenneth Feinberg, an attorney who managed the 9/11 Victim Compensation Fund, will design and administrator of a new fund to help people affected by the Boston Marathon bombing.

BOSTON -- The sight of bright blue and yellow windbreakers and t-shirts have become an instant symbol of Boston's healing and unity since Monday's double bombing.
The flashy colors are worn mainly as the official gear of the marathon. Blue is for the 23,000 runners and yellow is for the thousands of volunteers. Adidas also produces versions of the merchandise that's available to the paying public."This is my sport. This is my city," said Kim Stemple, a race volunteer wearing a lemon yellow jacket available on Thursday
"We know each other. We're each other's best therapy," she said about other volunteers.
Griffin Schroeder donned the blue runners' jacket as he stood near a memorial on Boylston Street before heading back to Wisconsin.
"It's out of respect," the 27-year-old said, adding that it's a symbol of completely the grueling event. "It's a very important accomplishment."
The windbreaker is an open invitation to talk with other marathoners. "I might ask someone if they finished the race. Or if I see someone we give a nod to each other."
Volunteer Susan Furgal of Brockton, Mass wept Thursday as she wore hers near the bomb site.
"I had to make myself come back," she told HuffPost.
Others find simple comfort in displaying that they were a part of the marathon.
"I just feel good wearing it," said Lene Henricksen, 51, from Denmark who was interrupted by the attack before finishing the 26.2 mile course. "This should never happen again. The marathon should go on."
Griffin Schoder wears the blue runner's jacket "out of respect" for the attack, but also because he's proud to have completed the testing race.

The race was called off before Henricksen, of Denmark, got to the finish line. She had the misfortune of traveling to New York for last fall's marathon that was canceled due to Hurricane Sandy.
From The Huffington Post's Christina Wilkie: Relatives of bomb victims who remained in the Intensive Care Unit of Massachusetts General Hospital in Boston on Thursday were unable to watch President Obama's tribute to those killed and injured in the blast, but they were nonetheless very keen to know what the president said. One family member of a renect amputee sent a text to HuffPost during the speech that said, "ICU has no TV's! How is it?" By all accounts, it was a very good speech.
