Harvard Medical School Targeted by Intentional Explosion, Investigation Underway

An intentional explosion occurred early on November 1 at Harvard Medical School's Goldenson Building in Boston, causing no reported injuries. A Harvard University police officer responding to a fire alarm saw two masked individuals fleeing the scene, prompting authorities to release surveillance images to aid identification. The Boston Fire Department's Arson Unit confirmed the blast was deliberate, and a sweep of the building found no additional explosive devices. The suspects wore masks and sweatshirts, with one described as wearing khaki pants and a brown hooded sweatshirt, and the other in dark plaid pajama pants and a dark hooded sweatshirt. The incident is being investigated by Harvard University Police in coordination with local, state, and federal agencies, including the FBI's Boston Division. Details about the type of explosive device and the extent of damage to the building, which houses parts of the neurobiology department, have not been disclosed.
