A man who said his daughter witnessed the incident said the person had been running through the park before setting himself ablaze.

"Police and rescue have responded," Krisjan Berzins tweeted. "They’re closing all surrounding streets right now."

Berzins also posted a video, which showed a person engulfed in flames.

WARNING: GRAPHIC VIDEO

"Video of the person that was literally engulfed in flames on the #WhiteHouse lawn," Berzins wrote. "Unbelievable."

The Secret Service said in a statement the unidentified man was being transported to a local hospital. His condition was not immediately known.

A similar incident happened last month when another man set himself ablaze while positioned along the White House’s North Fence Line.

The suspect was “operating an electric wheelchair-type scooter” when officials say he set his outer jacket on fire, the Secret Service said at the time.
