The tube service has been partially suspended in west London after reports of an explosion at Parsons Green underground station.
A Transport for London spokeswoman said the District line had been suspended between Earls Court and Wimbledon due to a security alert.
The Metropolitan and British Transport police forces, including armed officers, were at the scene, along with the London ambulance service, though none was immediately able to provide further details on what had happened.
One witness said there were injuries at the station after a “stampede” of passengers.
Media technology consultant Richard Aylmer-Hall, 53, was sitting on the District line train bound for central London at about 8.20am when he said panic unfolded around him.
“Suddenly there was panic, lots of people shouting, screaming, lots of screaming,” he said. “There was a woman on the platform who said she had seen a bag, a flash and a bang, so obviously something had gone off.”
He added: “I saw crying women, there was lots of shouting and screaming, there was a bit of a crush on the stairs going down to the streets. Some people got pushed over and trampled on. I saw two women being treated by ambulance crews.”
A reporter from London’s Metro newspaper reported seeing people with facial burns.
More details soon …
