A significant industrial fire broke out in a workshop building in Trollhättan's Håjum industrial area, prompting emergency services to respond around 11:00 AM. The blaze quickly escalated into a fully developed fire that spread throughout the entire facility and eventually reached the attic space. Rescue officials confirmed that the building could not be saved, with the structure collapsing during the firefighting efforts.

Emergency authorities issued a VMA (Important Message to the Public) warning residents in Trollhättan municipality about the heavy smoke development from the industrial property. The rescue commander urged all individuals in the area to go indoors and close doors, windows, and ventilation systems. The smoke drifted over a nearby residential area, with officials warning that the smoke was unhealthy and should be avoided under all circumstances.

By 2:30 PM, rescue services confirmed the building was lost as it was collapsing. The focus shifted to containing the fire and protecting adjacent buildings through water application. Ulrik Olsson, the duty officer at Fyrbodal rescue service, stated that their priority became limiting the fire's spread and conducting cooling operations on neighboring structures as the primary building continued to collapse.

Police have opened an investigation into suspected arson, though no suspects have been identified. According to police spokesperson Adam Isaksson Samara, initiating this type of criminal classification is not unusual for industrial property fires. The VMA warning was lifted around 4:00 PM, with rescue services transitioning to monitoring and final extinguishment operations through the night. The cause of the fire remains undetermined.

Norwegian aviation authorities faced significant disruptions as unidentified drones were spotted near multiple airports across the country, forcing flight diversions and temporary closures. At Brønnøysund Airport, police received the first report of a drone at 20:17 on September 30, with air traffic control personnel visually observing the unmanned aircraft flying dangerously close to the runway around 21:50. The incident prompted immediate police response and ultimately led to the airport's overnight closure.

The drone activity extended beyond Brønnøysund to affect Bardufoss Airport in northern Norway, where Norwegian Airlines flight DY338 was compelled to abort its journey from Oslo and return to the capital after an unknown drone was detected in the vicinity. The incident occurred at approximately 23:30 local time, marking an expansion of the drone crisis from major international hubs to regional airports serving Norway's remote northern communities.

Police efforts to locate the operators behind these drone incursions proved unsuccessful despite extensive searches. Morten Sorensen from the Nordland Police District confirmed that while authorities observed drones in the air, they were unable to locate any pilots associated with the aircraft. The coordinated nature of these incidents was evident as a Widerøe flight also had to divert to Trondheim after a drone was observed within the prohibited zone of Brønnøysund Airport.

Despite the disruptions, airport operations resumed normally by morning, with Avinor spokesperson Karoline Persen confirming that the last scheduled flight managed to land as planned before the overnight closures. The repeated nature of these incidents—with similar drone sightings reported at the same airport just days earlier—has raised concerns about aviation security in Norway's northern regions, where Bardufoss Airport serves both civilian and military operations in a strategically important location.
