Here's what happened:

The incident took place on Saturday morning.

The Harvard Crimson reported:

A device exploded inside the Goldenson Building in Harvard’s Longwood medical campus early Saturday morning, according to a message from the Harvard University Police Department to University affiliates. The Boston Fire Department Arson Unit responded to the incident and determined the explosion to be intentional.

The newspaper goes on to explain that the explosion took place in a medical building.

It reports:

The explosion took place on an area of the fourth floor of Goldenson, a Harvard Medical School building on the school’s main quad. An officer who responded shortly before 3 a.m. observed two individuals fleeing the building, according to the email sent by HUPD spokesperson Steven G. Catalano this afternoon.

Their photos can be seen above. According to reports, no one was injured in the explosions. A student named Joey Awad is reported as saying, "Like I felt it in my body. Was really scared, my heart was racing and then I tried to fall asleep and then like five minutes later, I heard another bang."

Suspects remain at large

At the time of this writing, the two suspects remain at large.

CBS News reports:

When the officer arrived to investigate, they saw two people running from the building. The officer tried to stop the two people, but was unable to identify them or prevent them from leaving. Police have since released surveillance photos that show two suspects with their faces covered inside the building. The public is being asked to help identify them.

The FBI has released a statement on the matter. It reads, "We're assisting our partners at the Harvard University Police Department and we're going to decline further comment at this time. We'll refer to the Harvard University Police Department."

Accordingly, the FBI, the Harvard University Police Department, and other local and state authorities are assisting in the investigation.

It remains unclear as to what the possible motivation for this attack can be.
