The explosion appeared to be intentional, but no injuries or structural damage were reported.
Harvard officials said the affected area has been cleared and all labs and equipment remain intact. The U.S. Attorney’s Office is expected to provide more details at a press conference in Boston later today.
The incident comes amid heightened tensions at Harvard, which has been under national scrutiny during ongoing negotiations with the White House over restoring federal funding and resolving lawsuits related to recent higher education reforms.
