The four victims, two men and two women, were injured in Lafayette Park, located directly outside the White House complex, according to the District of Columbia Fire and Emergency Medical Services Department.
Emergency medical crews were called to the scene just before 7 pm and transported the victims to the hospital with “critical, life-threatening injures,” fire department spokesman Vito Maggiolo said.
A portion of the park remained closed for more than an hour Thursday evening with emergency crews at the scene.
