More Explosions in London!
By Usayd
A number of Tube stations have been evacuated and lines closed after three blasts in what Met Police chief Sir Ian Blair says is a "serious incident".
Sir Ian appealed to Londoners to stay where they were and said the transport system was effectively shut down.
The minor explosions used detonators only, a BBC reporter said.
In addition, a Number 26 bus in Hackney Road in Bethnal Green had its windows blown out by a blast. There were no injuries.
