Four people were killed, 20 injured outside Parliament in a terror attack on Wednesday, March 22. Among the injured were 3 police officers. The attacker was also shot by the police at the scene. At this moment, a full investigation is underway.

A vehicle drove aggressively through pedestrians on the Westminster Bridge in London, leaving many with catastrophic injuries. Then a man with a knife tried to enter Parliament, but was stopped by the police. The entire compound went into lock down.

The attack has not been claimed by a terrorist group, but is still classified as a terrorist attack until further information comes forth. Since the attack, Scotland Yard has been flying the national flag at half mast in respect of those injured and killed.
