A car slammed into barriers outside Britain's Houses of Parliament on Tuesday morning, injuring at least two pedestrians, police in London say. The male driver has been arrested on suspicion of terrorism, reports the Guardian. Witnesses saw officers surround the car before the man was taken away in handcuffs. At 7:37am, "a car was in collision with barriers outside the Houses of Parliament," the Metropolitan Police said in a statement. Two people were taken to the hospital with injuries not believed to be life-threatening. This would be the fourth vehicle attack in London in less than 18 months, notes USA Today.
Witnesses say the crash, which involved a small silver car, appears to have been deliberate. "I think it looked intentional—the car drove at speed and towards the barriers," witness Ewalina Ochab tells the BBC. "I was walking on the other side of the road. I heard some noise and someone screamed. I turned around and I saw a silver car driving very fast close to the railings, maybe even on the pavement." She says the vehicle didn't appear to have a front license plate. Another witness, BBC employee Barry Williams, says he heard screams and then saw the car plow into a group of cyclists waiting at a traffic light before accelerating toward the barrier.
