A commuter whose train had just left the Parsons Green station in southwest London says there was panic after a woman on the platform saw what appeared to be an explosion. Richard Aylmer-Hall said he saw several people injured, apparently trampled as they fled.
"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 said. "Some people got pushed over and trampled on, I saw two women being treated by ambulance crews." He said he did not believe anyone was hurt by the actual device.
The London ambulance service said multiple crews had been dispatched.
One eye-witness said she saw a woman burnt from head to toe being taken into an ambulance.
