Three Norwegian Brothers Arrested in Bombing at U.S. Embassy in Oslo

Norwegian authorities arrested three brothers in their 20s on Wednesday in connection with a weekend bombing at the U.S. Embassy in Oslo, an incident police are investigating as a possible act of terrorism. Officials say the men are Norwegian citizens with a background from Iraq, and that Sunday’s explosion caused limited structural damage and no injuries. Oslo police official Frode Larsen said it is “natural” to view the attack in the context of the current U.S.–Israel war with Iran and that it may have deliberately targeted the embassy, though investigators have not yet established a motive. The blast came amid a wave of recent strikes on U.S. diplomatic facilities in Riyadh, Dubai and Baghdad and just a day before shots were fired at the exterior of the U.S. Consulate in Toronto, underscoring a widening threat environment for American missions even in normally quiet allied capitals. The State Department has already ordered non‑emergency staff out of several posts in the Gulf, and this case will add pressure for further security hardening and intelligence sharing with European partners.
