REPORT: One Bombing Suspect CaughtUPDATE: Suspect Died After Gun Battle

The Boston Globe is reporting:

One suspect in Monday’s Boston Marathon bombings has been captured, according to an official with knowledge of the investigation. Another remains on the loose in Watertown after a firefight with police. Authorities have established a 20-block perimeter as they search for him.

A scene of chaos descended on Cambridge and Watertown late Thursday night and early Friday morning, as police confirmed an MIT police officer was shot and killed, and an apparent carjacking led police on a wild chase into Watertown. Witnesses in Watertown said they heard explosions. Police officers were screaming about improvised explosive devices.

Authorities would not comment on whether the events were connected to Monday’s Boston Marathon bombings. At least one of the suspects in Watertown appeared to be a man in his 20s. FBI agents were on the scene in Watertown. The FBI source said early Friday it is “too early to speculate” on a relation to the Marathon bombing.

Please keep in mind how many times the media has been wrong this week.

UPDATE: Separately from tonight's action, the FBI has released new photos of the suspects.

UPDATE II: Apparently the man cited above is dead.

UPDATE III: Here's video taken of the apparent shootout.

UPDATE IV: Via NBC News.

Law enforcement sources said the suspects have international links and have been in the country legally for about a year. The suspects approached the MIT officer and shot him in head, the sources said. The two then stole the MIT officer's cruiser, robbed a nearby 7-11 and carjacked a Mercedes SUV, briefly kidnapping the driver, the sources said. At various points, the suspects threw explosives out the window of the moving car. The dead suspect had an improvised explosive device strapped to his chest and the law enforcement sources warned that the suspect on the run may as well.
