The FBI has released pictures and videos of two suspects in the Boston marathon bombings and sought the public’s help in identifying the men who are seen carrying backpacks near the finish line of the race before the blasts that killed three persons and injured over 180.

In the video footage from surveillance cameras along the route of the marathon, the two men are seen walking together on the sidewalks in the direction of the finish line.

The men, named ‘Suspect 1 and Suspect 2’, are wearing caps and carrying backpacks.

The FBI did not give any information about the ethnicity or nationality of the two young men.

The agency said one of the suspects set down a back pack at the site of the second explosion in front of the restaurant.

“Today, we are enlisting the public’s help to identify the two suspects. After a very detailed analysis of photo, video, and other evidence, we are releasing photos of the two suspects...They appear to be associated,” FBI Special Agent in-charge Richard DesLauriers told reporters here.

He said the agency has relied on the public to be its “eyes and ears” and people could play a critical role in identifying and locating the suspects.

“Somebody out there knows these individuals as friends, neighbors, co-workers, or family members of the suspects. Though it may be difficult, the nation is counting on those with information to come forward,” he said.

DesLauriers cautioned that in the event of the suspects being identified, the public should not approach them but inform law enforcement agents.

“We considered them to be armed and extremely dangerous.

No one should approach them. No one should attempt to apprehend them except law enforcement. Do not take any action on your own,” he added.
