An explosion at the United States Embassy in Oslo caused minor damage to the building early on Sunday, prompting a large police response in the Norwegian capital. Authorities said the blast occurred at around 1 a.m. local time near the entrance to the embassy’s consular section, located in the western part of Oslo. Despite the loud explosion and visible smoke rising from the area, officials confirmed that no injuries were reported.
According to Norwegian police, officers were dispatched quickly after several residents reported hearing a powerful blast near the diplomatic compound. Investigators later confirmed that an explosion had struck the embassy building, causing only limited structural damage. Police spokesperson Michael Dellemyr told local media that the explosion occurred close to the consular entrance and that authorities immediately began securing the area and assessing the damage.
Eyewitnesses said they saw smoke and debris near the entrance shortly after the blast. Emergency services, including bomb technicians and forensic teams, were deployed to the scene, while police used drones, helicopters, and sniffer dogs to search the area for possible suspects or additional explosive devices. Investigators later confirmed that no further devices were found in the vicinity.
The surrounding neighborhood was temporarily cordoned off as officers examined the site and gathered evidence. Local media reported a heavy police presence around the embassy compound, with nearby roads blocked while investigators carried out forensic work. Authorities have not yet determined the exact cause of the explosion or whether it was deliberate, and the investigation remains ongoing.
Officials from the embassy and the U.S. government had not issued a detailed statement immediately after the incident. Norwegian police said they are working closely with embassy officials as they continue to examine the circumstances of the blast. While some international tensions have recently affected U.S. diplomatic sites worldwide, investigators said it is too early to link the Oslo incident to any broader conflict or political motive.
Authorities have urged anyone who may have witnessed suspicious activity in the area around the time of the explosion to contact police as the investigation continues. Meanwhile, security measures around diplomatic buildings in the city remain heightened while officials determine what caused the blast.
