This comes from the Daily Mail, I'll try to get it all verified -

Up to a dozen people have been killed in a deadly explosion and up to 60 people have been injured after two large explosions went off near the finish line of the famous Boston Marathon today, leaving behind a scene of unimaginable carnage.

Law enforcement sources told the New York Post of the body count, and said that the first explosion happened at the Fairmont Hotel.

Eyewitnesses at the scene said there were two loud explosions about five seconds apart, and emergency vehicles crowded the scene.

Witness Dave Weigel said via Twitter minutes after the explosion: ‘I saw people’s legs blown off. Horrific. Two explosions. Runners were coming in and saw unspeakable horror.'

Police told the Boston Globe that are they still finding 'secondary devices,' and pleading with anyone still in the area to leave at once.

A controlled explosion was set for outside the city library.

A source who was speaking with authorities told MailOnline that there were shotgun shells in two explosions, which sprayed onlookers and runners with massive amounts of shrapnel, though the statement has not been confirmed by authorities.

One witness said 'there was blood everywhere.'

Boston’s Lenox Hotel that serves as the headquarters for the Boston Marathon was locked down on Monday after a security incident near the finish line. Two blasts were heard by reporters in the media center.

Authorities closed off the finish line and urged anyone in the area to stay away from trash bins.

Andrea Storer, who witnessed the blast, told the Boston Globe: 'It was huge. There had to be people killed. There had to be'

NECN reporter Jackie Bruno posted on Twitter: 'I saw people's legs blown off. Horrific. Two explosions. Runners were coming in and saw unspeakable horror.

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."

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. Biden said during the call that his prayers were with those who suffered injuries.

Vice President Joe Biden has released a statement regarding the Boston Marathon bombings.

'Our prayers are with those people in Boston who have suffered injuries. I don’t know how many there are.'

State and local officials told CNN's John King that there was no known credible threat prior to the explosions.

The marathon said in a statement: 'There were two bombs that exploded near the finish line in today's Boston Marathon. We are working with law enforcement to understand what exactly has happened.'

Competitors and race organizers were crying as they fled the chaos. Bloody spectators were being carried to the medical tent that had been set up to care for fatigued runners. A man was pictured with his lower leg blown off.

'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 told the Associated Press that 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.'
