Overview

• An explosion struck the Pilestredet/Bislett area, and bomb technicians later carried out a controlled detonation of a second device described as a military‑style hand grenade.
• No injuries were reported, and authorities issued a rare citywide mobile alert urging residents to keep away from windows due to remaining explosives at the scene.
• Police apprehended one suspect for questioning, while local media reported the detainee is 13 years old, a detail not confirmed by authorities.
• Investigators’ working hypothesis is a confrontation between criminals, and officers are seeking more information and any other people involved.
• The blasts occurred near a university campus and roughly 500 meters from the royal palace and the Israeli embassy, with separate drone sightings near regional airports reported the previous day without an established link.
