just to let you know one person has been injured on the warren street tube incident
Dummy explosions using detonators only have sparked the evacuation of three Tube stations and the closure of three lines, a BBC correspondent has said.
Police cordoned off large areas around Warren Street, Oval and Shepherd's Bush Tube stations.

Emergency services also attended an incident on a route 26 bus in Hackney Road in Bethnal Green.

There were reports of smoke coming from two of the stations. There are no reports of any injuries.

The whole of the Northern Line has been suspended, along with the Victoria Line and the Hammersmith and City.

A spokesman for London Underground said the nature of the incidents was unknown.

One hospital, near Warren Street station, has started its emergency plan.

Sosiane Mohellavi, 35, was travelling from Oxford Circus to Walthamstow when she was evacuated from a train at Warren Street.

"I was in the carriage and we smelt smoke - it was like something was burning. "Everyone was panicked and people were screaming. We had to pull the alarm. I am still shaking."

But a BBC reporter outside Warren Street station said there was no sign of smoke outside.
