The blast caused only ‘minor material damage’ to one of the building’s entrances

The US embassy in Oslo was hit by an explosion in the early hours of Sunday but no one was injured, police in the Norwegian capital said, adding the cause was not immediately known.

The blast occurred around 1am local time and caused only “minor material damage” to one of the building’s entrances, Oslo police said in a statement.

Investigators were examining the scene, while dogs, drones, and helicopters were involved in the search “for one or more potential perpetrators”, it said.

“Police view such incidents in public spaces as very serious, and are investigating the case with substantial resources and high priority.”

Police commander Michael Dellemyr told TV2 police would “not comment on anything related to the type of damage, what it is that has exploded and similar details, beyond the fact that there has been an explosion” because “it is very early in the investigation”.
