BOSTON - The Federal Bureau of Investigation has released the photos of the suspects in the bombings at Monday's Boston Marathon.
The videos appear to be taken on numerous cameras throughout the area Monday morning.
"One of them was seen putting down a black backpack at the site of the second blast in Monday's attack," said NBC News. "Both were seen walking together through the crowd."
Both men in the photos are wearing baseball caps, and appear to be associated.
"We consider them to be armed and extremely dangerous," the FBI said of both suspects. "No one should approach them...If you see these men, contact law enforcement."
The agency asks the public to a hotline, 1-800-CALL-FBI, with tips.
