Monday’s attack at an Ariana Grande concert in Manchester, England, is the latest in a series of terrorist attacks and threats that have struck the United Kingdom since 2005.

Though Britain was the scene of a large number of terrorist incidents inspired by the conflict in Northern Ireland in earlier years, most of the recent attacks have been attributed to Islamic extremists.

They have resulted in multiple deaths and dozens of injuries.

On two other occasions, law enforcement officials averted what might have been a serious attack.

Westminster Bridge attack

Three people were killed and dozens injured when a car driven by 52-year-old Khalid Masood mounted the curb on Westminster Bridge near the British Parliament and plowed into pedestrians. A fourth victim, police officer Keith Palmer, was fatally stabbed by Masood just inside the gates leading to Parliament.

Masood was shot dead by police.

Authorities carried out a controlled explosion and there were no reports of injuries. Damon Smith, a teenager who had reportedly converted to Islam, was later charged with the crime.
