Two female protesters in Seattle have been hit by a speeding car that drove into a crowd demonstrating on an interstate highway, killing one and leaving the other in a serious condition.
Seattle has been the scene of numerous protests, some on interstate highways, since the May 25 killing of black man George Floyd while in police custody.
Summer Taylor died late on Saturday at Harborview Medical Center, a spokeswoman told Reuters, adding that Diaz Love, the other injured protester, was in the intensive care unit.
Police said the car driver, a 27-year-old Seattle man, was arrested at the scene of the accident, and faces multiple felony charges.
"He was placed in custody when troopers arrived on scene," Chase Van Cleave, a Washington State Patrol trooper told Reuters by phone earlier.
"The investigation is still ongoing. At this time we're not suspecting drugs or alcohol as a factor in the crash."
Investigators do not know if the driver intended to hit the demonstrators, he added.
A video of the incident posted on social media shows a lone white car speeding up Interstate-5, swerving to avoid a van that was parked to block the roadway and heading toward a small group of panicked protesters who tried to scurry away.
The car can be seen striking two individuals, who were both flipped over its roof to land on the pavement.
