Overview
- The early‑Sunday explosion was caused by an improvised explosive device that damaged the consular entrance but injured no one.
- Investigators believe one brother planted the device and the other two assisted, with all three in custody on suspicion of a terrorist bombing.
- The suspects are Norwegian citizens in their 20s with Iraqi background and had not previously been known to police, officials said.
- Multiple lines of inquiry are active, including potential foreign‑state direction or links to criminal networks, and a separate probe into a video posted to the embassy’s Google Maps page showing Iran’s late leader and a Farsi message.
- A U.S. official told AP the device was concealed in a backpack, while Norwegian authorities increased security around the embassy and reported no sign of an ongoing public threat.
