At least 23 people were injured when a device exploded in the London Underground train Friday morning, in what British authorities are treating as a terror attack. None of the victims are believed to have serious or life-threatening injuries, according to the London Ambulance Service.
Photos and videos from the scene show a white bucket on fire inside a plastic supermarket bag. The inside of the Tube train carriage does not appear to be damaged, but witnesses reported seeing people with injuries, including burns to the face, arms, and legs, according to The Guardian.
Prime Minister Theresa May responded to the attack and tweeted, "My thoughts are with those injured at Parsons Green and emergency services who are responding bravely to this terrorist incident."
Police and paramedics were called to the scene right after the device went off around 8:20 a.m. local time, the BBC reported. Natasha Wills, assistant director of operations at London Ambulance Service, said "multiple resources" were sent to the scene, "including single responders in cars, ambulance crews, incident response officers, and our hazardous area response team, with the first of our medics arriving in under five minutes," reported the BBC.
"Our initial priority is to assess the level and nature of injuries. More information will follow when we have it."
Passengers reported "panic" at the scene, with BBC London presenter Riz Lateef, who was on her way to work, saying: "There was panic as people rushed from the train, hearing what appeared to be an explosion.
"People were left with cuts and grazes from trying to flee the scene. There was lots of panic."
Sophie Raworth, another BBC News presenter, said she saw a woman with multiple burns being carried from the scene on a stretcher.
The British Transport Police called on people to remain vigilant and report suspicious behavior.
London Mayor Sadiq Khan said he was in touch with the Metropolitan Police about the incident and urged the public to follow the force's Twitter account for updates.
