A man may have set himself on fire Friday afternoon on the National Mall in Washington, police and witnesses reported.
The unidentified man was taken to the hospital with "life threatening injuries," a D.C. Fire Department spokesman told The Washington Post.
The man was "conscious and breathing" when firefighters arrived, a D.C. police spokeswoman told the paper. She said police had not yet established the cause of the fire.
Witnesses told NBC Washington and the Post that the man poured gasoline on himself, then set himself on fire about 4:25 p.m. ET at Seventh Street and Jefferson Drive, near the Air and Space Museum.
Several joggers took off their shirts to extinguish the flames. A red gasoline canister and yellow tarp were next to the man.
Nicole Didyk, who was jogging past, told the Post that one of the rescuers told her the man was facing the Capitol when he set himself alight. He later thanked the Good Samaritans. She said the man's "face and arms were charred" and the ground around him was on fire.
A woman walking on the Mall said the air "smelled strongly of burning flesh."
U.S. Park Police closed an area of the mall 7th Street between Constitution Avenue NW and Independence Avenue SW.
