The FBI released photos of two men, seen carrying back packs at the Boston Marathon, who are suspects in the bombings that killed 3 people and injured over 100.

The FBI is also asking anyone with visual images, video, and/or details regarding the explosions along the Boston Marathon route and elsewhere, to send them to their website.  No piece of information or detail is too small. You can also call 1-800-CALL-FBI (1-800-225-5324), prompt #3, with information.

You can see more photos of the suspects at the FBI website.  There is also video surveillance of the men walking along the route.
