The FBI has released photos of two suspects in the Boston Marathon bombings and is asking for the public's help in identifying them.
FBI Agent Richard DesLauriers says one of the suspects is believed to have planted a device outside a restaurant near the finish line of the race. He says both suspects are considered armed and extremely dangerous.
Within moments of the FBI releasing the images on its website, the agency's website crashed.
The explosions Monday killed three people and injured more than 180.
The images were released hours after President Barack Obama and first lady Michelle Obama attended an interfaith service at a Roman Catholic cathedral in Boston to remember the victims, including an 8-year-old boy.
The FBI's tipline for leads is 800-CALL-FBI (800-225-5324).
