The 2017 Westminster attack was a suspected terror attack that occurred on 22 March 2017 on Westminster Bridge, in Parliament Square and within the grounds of the Palace of Westminster in central London. A four-wheel drive vehicle was driven into a crowd of people near the palace gates, and an attacker stabbed people, at least one of them being a police officer. Two people—one woman and one police officer—are confirmed[citation needed] to be dead.[2][3][4][5][6]
