Breaking news update:
The FBI has released images of two suspects in the Boston Marathon bombing, asking the public to help identify them.
The images include 11 photographs and one video of the two "suspects."
"The FBI developed a second suspect," said FBI Special Agent Richard DesLauriers, citing extensive investigation at an early evening press conference. "Suspect 1, is wearing a dark hat. Suspect 2—set down a backpack" at the second bombing site, DesLauriers said.
The two suspects can be seen walking together through the marathon.

According to the Boston Globe, law-enforcement officials on Thursday intend to release images of two suspects they hope the general public can help identify in connection with Monday's bombing of the Boston Marathon.
The paper reports:
Authorities have clear video images of two separate suspects in the Boston Marathon bombings carrying black bags at each explosion site and are planning to release the images today in an appeal for the public’s help in identifying the men, according to an official briefed on the case.
The official said that the two suspects were seen separately on videotape -- one at each of the two bombing sites, which are located about a block apart.
The official, who spoke this morning on the condition of anonymity, said the best video has come from surveillance cameras on the same side of Boylston Street as the explosions. The official said the widely reported Lord Taylor surveillance camera, and snapshots from individual cell phone camera users, have not provided the clearest images.
It was unclear why authorities did not publicize images of the unidentified suspects yesterday. President Obama is visiting Boston today, and the timing of a law enforcement briefing remained unclear.
A law-enforcement official who spoke to the New York Times said a final decision on whether to release the photos had not yet been made, but the person said it was “more likely than not” that they would.
