On 15 September 2017 an explosion occurred on a London Underground train at Parsons Green, injuring 29 people. The improvised explosive device was placed in a bucket but did not fully detonate, with injuries being largely burn related. No fatalities were reported. An 18-year-old Iraqi refugee was arrested the next day at the Port of Dover. He was subsequently sentenced to life imprisonment with a minimum jail term of 34 years, having found to have been in contact with members of Islamic State.
