SWEDEN, 31 AUG 2023: Ten workers got stuck in a 7.5 kilometre long tunnel, 70 metres underneath Stockholm on Thursday. Smoke had filled the tunnel, used for electricity supply infrastructure, from a transport belt that malfunctioned. They managed to get to a safe room, and were later evacuated from the tunnel by the electricity company’s own personnel. Two other workers in the tunnel were transported to hospital after inhaling the smoke.
