On 15 September 2017, at around 08:20 BST (07:20 UTC), an explosion occurred on a District line train at Parsons Green Underground station, in London, England. Thirty people were treated in hospital or an urgent care centre for injuries, mostly burns, caused by a crudely assembled "bucket bomb" with a timer containing shrapnel and the explosive TATP that failed to detonate fully.
