OSLO — An incendiary device hidden inside a backpack exploded at the entrance to the United States Embassy in Oslo shortly after 1 a.m. local time on Sunday, shattering glass, scorching a tiled floor and sending thick smoke billowing into the surrounding street. No one was injured, and no arrests have been made.
The blast struck the public entrance to the Consular Affairs office of the embassy, located in the Morgedalsvegen district of western Oslo, approximately seven kilometres from the city centre. Photographs taken at the scene showed cracked glass doors, shattered panes strewn across snow-covered ground, and dark scorch marks on the floor just inside the entrance — evidence of a device that, while limited in destructive power, was deliberately placed at a high-profile diplomatic target.
Frode Larsen, head of the Oslo police joint investigation and intelligence unit, confirmed that investigators regard the US Embassy itself as the intended target. Terrorism is being treated as one hypothesis, though Larsen was careful to stress that police are not locked into that conclusion and are actively pursuing multiple lines of inquiry. "We are working based on several hypotheses," he said, adding that authorities are seeking witnesses who may have seen or heard anything connected to the incident.
Large police resources were deployed to the area around the time of the explosion, with officers conducting extensive searches of the surrounding neighbourhood. Michael Dellemyr is leading the operational police response on the ground. The PST — Norway’s domestic police security service — called in additional personnel following the blast, though the country’s national terror threat level was not raised in the immediate aftermath. Martin Bernsen, a communications adviser for PST, confirmed the service’s involvement in the investigation.
The US State Department confirmed awareness of the incident and announced it had opened its own investigation. Norwegian authorities are coordinating closely with US diplomatic staff, reflecting the sensitivity of an attack on foreign sovereign premises.
Norwegian Foreign Minister Espen Barth Eide condemned the explosion in unequivocal terms, calling it "unacceptable" and emphasising that Norway places the highest importance on the security of diplomatic missions on its soil. Barth Eide personally contacted Eric Meyer, the US Embassy’s chargé d’affaires, to express concern and offer assurances of full Norwegian cooperation. Justice and Public Security Minister Astri Aas-Hansen is also monitoring the situation as the investigation develops.
Police stated that nothing in their current assessment suggests any ongoing danger to the general public, though they urged anyone with relevant information — whether they witnessed unusual activity near the embassy or heard the explosion — to come forward immediately.
The attack comes at a period of heightened global concern over the security of Western diplomatic facilities. While the relatively contained nature of the device and the absence of casualties may suggest a symbolic rather than mass-casualty intent, the deliberate targeting of a US consular entrance with an incendiary device will inevitably draw scrutiny from both Norwegian and American security agencies.
The investigation remains in its early stages. No individual or group had claimed responsibility as of Sunday morning, and the identity and motive of whoever placed the device remain unknown. Both Norwegian and US authorities have pledged to pursue the case with significant resources.
