Several federal buildings in downtown Washington lost power for a short time Monday morning as a result of a "transformer explosion" at the Office of Personnel Management, according to D.C. Police Spokesman Araz Alali.

Outages were reported at the White House, State Department and Federal Reserve. Other departments that experienced outages Monday included the General Services Administration (GSA), Federal Deposit Insurance Corporation (FDIC), and the Labor Department, according to Alali. The Smithsonian Metro station also experienced an outage.

No injuries have been reported, and the outage was not a result of "terrorist activities" or "foul play", Alali said.

The White House outage only lasted for a few seconds, according to reporters in the building when it happened. But the OPM was evacuated, and State Department employees were asked to shelter in place, while Emergency Services responded to the initial call.
