An explosion occurred at Harvard, intentionally caused, and the FBI has confirmed the arrests, without providing details about the suspects or motives.

The FBI office in Boston has confirmed arrests related to an explosion that occurred Saturday morning on the fourth floor of the Goldenson building at Harvard, which houses laboratories and offices of the Department of Neurobiology. University officials stated that the explosion did not affect equipment or laboratories.

Boston firefighters determined that the explosion was intentionally caused, and subsequent checks did not uncover any other explosive devices. A campus police officer observed two individuals fleeing the building after the incident. This event comes amid a tense context for the Harvard community, which has been affected by the Trump administration's plans to reform higher education institutions and negotiations to restore federal funding.
