WASHINGTON -- Four people are in critical condition following an apparent lightning strike at a Washington, D.C., park, authorities said Thursday evening.
D.C. Fire and EMS said it had responded to Lafayette Park, located in front of the White House, and was treating the four patients that were found in "the vicinity of a tree."
Two men and two women were transported to area hospitals with "life-threatening injuries" after the apparent lightning strike, D.C. Fire and EMS said.
Officials said it's still unclear what the adults were doing prior to the lightning strike, if they knew each other and why they were in the park. The identity of the victims could not be confirmed while the investigation is still ongoing, officials said.
Uniformed U.S. Park Police officers and members of the Secret Service were also on the scene and immediately rendered aid to the victims, an EMS official said during a news conference.
The National Weather Service had issued a severe thunderstorm warning for the area Thursday evening.
