A single terrorist attacked Westminster killing four people, included a police officier and wounding 40 other civilians, before being killed. He indiscriminately ran into people with a car on Westminster Bridge. The use of the vehicle to attack civilians was a direct copy of an Islamic State tactic used previously with murderous effect in Nice and Berlin. The initial working theories of the police investigation are the attacker was inspired by Isis and was most likely a “lone actor”.
