Blast outside U.S. Embassy in Oslo investigated as possible terrorist attack | 9 March 2026 | Norwegian police are investigating an explosion outside the U.S. Embassy in Oslo as a possible act of terrorism. The incident occurred amid heightened security for American diplomatic missions and the U.S.-Israel war with Iran. The blast happened at around 1:00 AM on Sunday and caused minor damage to the entrance of the diplomatic compound. An explosive device appears to have been thrown at the building, Grete Metlid, the head of operational services at Oslo police, said at a press conference. Photographs from the scene show broken glass and fallen lamps near the entrance. Shortly after the explosion, a video appeared on the embassy’s Google Maps page showing Iran’s slain supreme leader, Ayatollah Ali Khamenei, accompanied by a message in Arabic: “God is great. We are the victors.”
