• Three brothers of Iraqi origin arrested in connection with the US embassy bombing in Oslo.
• Norwegian police suggest possible motivations may involve foreign state actors.
• Explosion occurred at the embassy’s consular section, causing minor damage but no injuries.

Norwegian police have arrested three brothers, all in their 20s and holding Iraqi citizenship, in connection with an explosion outside the US embassy in Oslo. The blasts, which occurred early on a Sunday morning, caused minor damage but resulted in no injuries. Police prosecutor Christian Hatlo confirmed their arrest on Wednesday afternoon, stating that they are suspected of a "terrorist bombing" aimed at the embassy, indicating the use of an improvised explosive device (IED) at the building's entrance, according to CBS News, South China Morning Post, and Al Jazeera.

Hatlo stated that the police are exploring multiple theories regarding the attack's motive, including the possibility of a "government entity" being involved, particularly due to the specific target of the US embassy amidst a tense global security climate. He noted that this line of inquiry is justified given the ongoing conflicts involving Iran and the US, according to BBC and Dawn.

The police revealed that, during the investigation, they believe that one brother may have placed the IED while the other two assisted in the act, with none of them having prior criminal records. Additionally, police examinations include surveillance footage and a suspicious video that was posted to the US embassy's Google Maps page, which hinted at the bombing's motivations, as reported by South China Morning Post, Al Jazeera, and BBC.

Iran's ambassador to Norway has denied any involvement, stating it is "unacceptable" for the country to be implicated, addressing concerns of potential proxy involvement amidst heightened diplomatic tensions. The incident comes as US embassies globally are on high alert due to ongoing conflicts in the Middle East, highlighting rising concerns of safety at diplomatic establishments, according to CBS News, Dawn, and South China Morning Post.
