There are reports from Norway that police are evacuating parts of Oslo after finding a suspicious object.
It is believed the area around the US Embassy and the adjacent Royal Palace are being evacuated, after the device was discovered under a parked car.
The neighbourhood is also home to residential and office buildings.
Reports say police have also blocked off streets around the embassy.
Anders Breivik admitted bombing the government buildings in Oslo in July of last year, causing the deaths of eight people.
