The Boston Police Department, during a press conference at the Westin Hotel following the deadly blasts on the course of the Boston Marathon, confirmed a third blast at the John F. Kennedy Presidential Library this afternoon. Police said they are not aware of any injuries from that blast. [embedgallery id=134983]

 

The first two simultaneous blasts occurred around 2:50 p.m about 50 to 100 yards apart along the marathon course.

 

Boston Police Commissioner Ed Davis said he does not have the number of casualties, though two people have reportedly been killed and dozens injured. Davis said the department immediately activated an emergency response and sent resources. He recommended people stay inside their homes and avoid large crowds.

 

A phone number for people trying to locate loved ones who participated in the marathon has been set up: 617-635-4500.

If anyone has information about the blasts, they can call 1-800-494-TIPS

"People should be calm, but they should understand this is an ongoing event," Davis said.

He added that they are not looking for any particular type of vehicle.

When asked whether the incident is being treated as terrorism, Davis replied, "You can reach your own conclusions based upon what happened."

Davis also said that in their panic to flee the scene, many people left bags behind.

"All bags and parcels left behind being treated as a suspicious device at this point," he said, adding that people may hear additional explosions from controlled detonations of those parcels.
