Norwegian police believe they have determined the cause of a massive fire that destroyed over 100 terraced houses. The blaze is suspected to have started either accidentally or spontaneously, according to Simon Gerhardsen, head of the forensic investigation team. While the origin is believed to be identified, authorities warn the fire could reignite due to extremely hot ground temperatures. Several Norwegian newspapers reported on the findings of the ongoing investigation. The incident caused widespread destruction within the residential area. Further monitoring of the site is underway to mitigate the risk of renewed flames.
