Air accident investigators say there is no evidence a fire on board an empty Boeing 787 Dreamliner aircraft at Heathrow airport in London was caused by the plane's batteries.

The fire on the parked Ethiopian Airlines plane closed the airport's runways for 90 minutes.

At the start of the year, all 50 Dreamliners in service worldwide were grounded after two separate incidents concerning batteries.
