Authorities say the blast was caused by an improvised/incendiary device placed at the embassy entrance and resulted in only minor material damage and no injuries.

The device is reported to have detonated from a backpack outside the Consular Affairs office, according to a U.S. official who spoke on condition of anonymity.

Norwegian authorities launched an immediate on-scene response and a joint investigation.

Investigators searched the scene overnight and deployed dogs, drones and helicopters to look for one or more suspects.

The case is being handled by the Oslo police and the Norwegian domestic security service (PST).

The U.S. Embassy referred inquiries to the State Department, which said it is aware of the incident, has opened its own investigation, and thanked Norwegian authorities for their support.

Norwegian officials have not ruled out terrorism: police have described a terrorist act as one hypothesis while keeping an open investigation into other causes, and law-enforcement leaders are overseeing a joint investigation and intelligence effort.

Authorities have also said they have no new information about an attacker’s motive as the probe continues.

Police released heavily pixelated surveillance images of a suspect linked to the explosion, showing a person with their face concealed, wearing dark clothing and carrying a backpack, and authorities continue to seek whoever placed the device.

The reported image release and description of the suspect align with on-scene accounts that the device was carried in a backpack at the embassy entrance.
