Norwegian authorities are investigating an explosion that occurred early Sunday morning outside the United States Embassy in Oslo. The incident, which caused minor damage to an embassy entrance, involved an incendiary device, according to police. No injuries have been reported, and authorities are actively searching for individuals responsible and their motive.

Incident Details

On Sunday, March 8, 2026, at approximately 1 a.m. local time, reports of a "loud bang" or explosion were received from the vicinity of the U.S. Embassy in Oslo, Norway. The blast resulted in minor damage to an entrance of the embassy, specifically the Consular Affairs office. Witnesses described the street being covered in thick smoke following the explosion. There have been no reported injuries in connection with the incident.

A U.S. official, speaking anonymously, stated that the explosion involved an incendiary device that was placed inside a backpack and detonated near the entrance.

Investigation Underway

Norwegian police have established a cordon around the embassy as part of their investigation. Frode Larsen, a representative and leader of the Oslo police joint unit for investigation and intelligence, confirmed that the explosion was caused by an incendiary device.

Investigators believe the U.S. Embassy was the intended target.

Police are actively searching for perpetrators and their motive and are also seeking to speak with witnesses. While considering a targeted attack on the embassy given the current security situation, investigators are examining multiple hypotheses and have not committed to a single one. No arrests have been made in connection with the incident.

The Norwegian Police Security Service (PST) has deployed additional personnel to assist with the investigation. PST communication adviser Martin Bernsen confirmed that the country's terror threat level has not been altered following the incident. The U.S. State Department has also opened its own investigation and thanked Norwegian authorities for their support.

Astri Aas-Hansen, Norway's Minister of Justice and Public Security, described the incident as "unacceptable" and stated that it is being treated with "utmost seriousness." She noted that police are dedicating substantial resources to the case and that the situation does not indicate any danger to the public.

The U.S. Embassy in Oslo referred media inquiries to the U.S. State Department. Oslo police did not provide further details immediately after the incident.
