Explosion in Oslo center prompts police response as explosives remain at scene

Emergency services were dispatched to central Oslo after an explosion in the Pilestredet area, with police warning that there could be additional devices at or near the scene. Authorities said residents should stay away from windows and avoid the area as investigators assess the situation. There were no immediate reports of injuries as responders worked to secure the site.

The blast occurred in a busy part of the city near a university campus, a short distance from Oslo’s royal palace and the Israeli embassy. Police shut off the street while firefighters stood by and a number of police helicopters were deployed to monitor the scene. Nearby tram service was halted, and the wider tram network was affected as emergency crews established perimeters and searched for further threats.

Oslo Police operations manager Øyvind Hammervold told TV2 that investigators are working on the basis that a hand grenade may have been planted. The police also confirmed to VG that the bomb squad is at the scene and evaluating the device. In a police statement, authorities cautioned that there are explosives at the site that have not yet been detonated and reiterated the instruction for people to stay away from windows and to avoid visiting the location. The message also noted that, while the area was not being evacuated, people should remain clear of the vicinity due to the ongoing risk.

Authorities said there have been no reported injuries linked to the blast. The incident comes amid heightened security concerns following drone sightings near Oslo’s and Copenhagen’s airports reported about a day earlier. Officials did not indicate a possible motive and urged the public to remain vigilant and to follow official guidance as the investigation continues. This is a developing story, and more information is expected to be released as authorities gather details and assess any potential threats.
