Terrorist: 2017 Westminster Attack

British Islamist terrorist attack that occurred on Westminster Bridge, in Parliament Square and within the grounds of the Palace of Westminster, in central London. A vehicle was driven into a crowd of people near the palace gates, and a police officer was stabbed. The man who stabbed the police officer was then shot by other officers. Five people—three pedestrians on the bridge, the stabbed police officer and the assailant—were confirmed dead the same day. Additionally, 12 people received serious injuries, some described as "catastrophic", and eight others were treated for less serious injuries at the scene.

The four dead victims were from the United Kingdom, and the survivors included people from South Korea, France, Romania, Italy and Australia.

The motivation was suspected to be linked to Islamic extremism. It was the first major attack to occur in London since the 7 July 2005 London bombings.

In response to the attacks, the devolved National Assemblies in Scotland and Wales both suspended proceedings. International reactions were swift in condemning the attacks and expressing sympathy and support for the victims.
