LONDON (REUTERS/AFP) – British police say they have declared an explosion on a train at a London underground station on Friday (Sept 15) as a terrorist incident.

A Reuters witness saw ambulances, fire engines and a helicopter at Parsons Green station in West London where the Metro newspaper reported that passengers had suffered facial burns from a blast and others had been hurt in a subsequent stampede.  

Outside the station, a woman was sitting on a pavement with a bandage around her leg while armed police patrolled.

A Reuters witness saw a woman being carried off on a stretcher with her legs covered in a foil blanket.

“We are aware of an incident at #ParsonsGreen tube station. Officers are in attendance,” London police said on Twitter.

The Telegraph reported one witness as having seen “a flash and a bang” in a bag holding the container, which is said to have had wires coming from it, on the train.

A Metro.co.uk reporter at the scene was quoted by the paper as saying that a white container exploded on the train and passengers had suffered facial burns. She said they were “really badly burned” and their “hair was coming off”.

“People were left with cuts and grazes from trying to flee the scene. There was lots of panic.” Ms Natasha Wills, assistant director of operations at London Ambulance Service said in a statement.

“Our initial priority is to assess the level and nature of injuries,” she said, adding the ambulance service had sent “multiple resources” to the station, including a hazardous area response team.

Appealing for calm, Foreign Secretary Boris Johnson told Sky News: “It really is important not to speculate at the moment.”

“Obviously, everybody should keep calm and go about their lives in a normal way, as normal as they possibly can.”

Transport for London said on Twitter that there was no service between Earls Court and Wimbledon on the District Line which runs through Parsons Green.

Britain has already suffered four attacks blamed on terrorists so far this year which killed 36 people.
