A large explosion has hit near government headquarters in the Norwegian capital Oslo.
The blast is thought to have caused damage to the offices of Norwegian Prime Minister Jens Stoltenberg and a number of other official buildings.
Initial reports suggested Mr Stoltenberg was unharmed.
At least eight people were injured in the city centre explosion, local media reports. No-one has said they were behind the attack.
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 newspaper.
No word yet on who is responsible, but it’s probably worth noting that Norweigian authorities stopped an al Qaeda plot last year, and just last week filed terror charges against Ansar al-Islam founder Mullah Krekar for threatening Norweigian politicians with death if he is deported.
