On 22 March 2017, a terrorist attack took place outside the Palace of Westminster in London, seat of the British Parliament. Khalid Masood, a 52-year-old Briton, drove a car into pedestrians on the pavement along the south side of Westminster Bridge and Bridge Street, injuring more than 50 people, four of them fatally. He then crashed the car into the perimeter fence of the palace grounds and ran into New Palace Yard, where he fatally stabbed an unarmed police officer. He was then shot by an armed police officer, and died at the scene.
