The Norwegian Police Security Service (PST) has stated that it is in close collaboration with the Oslo Police District regarding the recent explosion near the US embassy in Oslo. This incident took place in the early hours of Sunday, raising concerns about security in the vicinity of diplomatic missions. In light of this explosion, PST is actively evaluating whether there is a heightened risk of additional attacks in Norway. PST's communication advisor, Eirik Veum, emphasized the ongoing nature of their assessments and the collaboration with local authorities.

During a recent press briefing, PST confirmed that three individuals have been arrested in connection with the explosion. The authorities are investigating the details about these individuals, including whether they were previously known to the PST. However, when pressed for specifics regarding the background of the arrested persons, Veum declined to comment. This suggests that the investigation is still in its early stages and that sensitive information is being handled with care to ensure the integrity of the ongoing inquiry.

The implications of this incident are significant, as it calls into question the security measures surrounding diplomatic sites in Norway. As PST continues its threat assessment and works closely with the Oslo police, public awareness and confidence in local security measures will likely be a focus. The outcome of this investigation may also influence future policies regarding surveillance and prevention approaches to ensure the safety of both citizens and foreign entities operating within the country.
