The FBI has released photos and video of two men it has identified as suspects in the Boston Marathon bombings and wants the public's help in finding them, reports AP. Surveillance footage captured the men walking together near the finish line. Both are wearing baseball caps and both have backpacks. One is seen setting down his backpack near the site of the second blast, reports CNN. "We consider them to be armed and extremely dangerous," says the FBI's Richard DesLauriers. The images also will be available at FBI.gov. Those with tips can call 1-800-CALL-FBI.
