Three brothers have been arrested in Norway following an explosion outside the U.S. Embassy in Oslo on Sunday. Authorities believe an improvised device was detonated at the building's entrance, causing minor damage but no injuries.

The arrested individuals, all in their 20s, are Norwegian citizens with links to Iraq. Police have stated they are suspected of a terror bombing. Investigators are examining various motives, including potential involvement of a foreign state actor. A deleted video from Google Maps around the time of the incident, reportedly featuring Iran's former supreme leader, is also under review.

Emergency services responded to the embassy in Oslo's Ullern district early Sunday. Photos from the scene showed shattered glass and damage to the embassy's consular section. Norwegian officials have condemned the incident, emphasizing the importance of diplomatic mission security.
