Norwegian police have arrested three brothers in connection with an explosion at the United States embassy in Norway. The suspects are Norwegian citizens of Iraqi origin who were not previously known to law enforcement authorities.

Police prosecutor Christian Hatlo announced the arrests but provided limited details about the investigation. The men had no prior criminal record or history with Norwegian police services.

Authorities have not released information about the extent of damage from the embassy explosion or whether there were any injuries. The timing and specific circumstances surrounding the incident also remain unclear.

The arrests represent a significant development in what appears to be an ongoing investigation into the embassy incident. Norwegian police typically maintain strict confidentiality during active criminal proceedings.

Further details about the charges, investigation timeline, and the brothers' alleged involvement have not been disclosed by authorities.
