One of the busiest tube stations on London has been evacuated after smoke filled a train carriage.
Pictures on social media show grey smoke billowing out of the carriage on the Bakerloo line while passengers stand on the Oxford Circus platform covering their mouths and noses.
Other photographs show people standing in dark, smoke-filled carriages covering their faces with items of clothing.
