London Tube Explosion Leaves Commuters with Facial Burns

An explosion on a London Underground train has left commuters with “facial burns” after a “fireball flew down a carriage”.

Emergency services are at the scene in South London with early reports suggesting several are injured amid widespread panic.

There are reports of people fleeing the scene screaming with a reporter saying people are “really badly burned” adding that “their hair was coming off”.

An onlooker said a “fireball flew down a carriage” with panicked commuters diving out an open door.

A picture believed to have been taken on a District Line train shows a burning plastic bucket.

The blast appears to have come from the contents of a Lidl bag left by the tube carriage door.

Train services through the area have been halted with commuters reporting they were informed of a “security incident”.

Police is investigating the incident.
