D.C. Fire & EMS crews extinguished several fires at RFK Stadium on Tuesday evening.
The fires were located in "below-grade levels," fire officials said.
No injuries were reported.
Crews were called to the scene sometime before 5:30 p.m. In an update about an hour later, fire officials said crews were venting smoke and checking for any additional fires.
Video shared by D.C. Fire & EMS on Twitter showed several firefighters on the overgrown field of the old stadium as smoke appeared to drift from a lower level. A fire alarm could be heard chiming repeatedly.
The source of the fires was not immediately clear. Investigators were called to the scene.
