The UK has experienced four major terrorist attacks in 2017, which have left 36 people dead. The country's threat level is set at "severe," meaning it is considered highly likely that an attack will occur.
In March, a car attack occurred near Westminster Bridge, during which a man drove a car into a group of pedestrians before fatally stabbing an unarmed police officer. In June, eight people were killed and 48 were injured in a vehicle and stabbing attack in the vicinity of London Bridge.
On August 17, a van attack in Barcelona killed 14 people and injured over 100 more. Another person was killed in Cambrils a day later. In that incident, eight alleged terrorists were killed by Spanish police.
