“Right now there is a truck overturned on the E10 west of Morjärv. Nobody has been hurt but there is petrol leaking from the tank and emergency services are on their way there,” he said.
Police in Jämtland have also received reports of treacherous road conditions as motorists struggle to keep control of their vehicles.
