Huge explosion in Norway Prime Minister's office

BBC:

A large explosion has hit near government headquarters in the Norwegian capital Oslo.

At least one person was killed in the city centre blast, national broadcaster NRK reports.

The offices of Norwegian Prime Minister Jens Stoltenberg were damaged extensively but a government spokeswoman said he was safe.

At least eight people were injured, local media said. No-one has said they were behind the explosion.

Television footage from the scene showed rubble and glass from shattered windows in the streets - smoke was around some buildings. The wreckage of at least one car was in street.

All roads into the city centre have been closed, said the NRK, and security officials evacuated people from the area, fearing another blast.

Note how the BBC does not suggest who might be responsible. That leads me to believe the explosions were put in place by Muslim religious bigots who have been at war with Norway ever since the Mohammad cartoons were published. They have been thwarted at attacking the publisher and the cartoonist so they may have switched targets to the government.
