An explosion on a tube train at Parsons Green station in west London at 8:20am – the middle of the morning rush hour – has been declared a terrorist incident.
Police have confirmed the “detonation of an improvised explosive device” took place. It does not appear to have fully detonated, however. No-one has been arrested in connection with the incident.
At least 22 people are being treated in hospital following the incident, but no-one is thought to be in a serious or life-threatening condition. Police said most victims were suffering from “flash burns”.
Prime minister Theresa May has said her thoughts are with those injured and the emergency services responding, while London mayor Sadiq Khan urged Londoners to be vigilant. Both are attending a Cobra emergency meeting this afternoon.
US president Donald Trump appeared to claim on Twitter that the “loser terrorist” behind the attack was “in the sights of Scotland Yard”, but police in London have not disclosed this information publicly. A Met police spokesperson told BuzzFeed News the president’s tweets were “unhelpful”.
