A woman was killed in a vehicle collision earlier today on the main A970 road between Lerwick and Hillswick.
Another passenger in the car, believed to be an elderly woman, has been taken to the Gilbert Bain Hospital.
The incident occurred just south of the Halfway House at Sandwater and the road is currently closed between the South Nesting and Weisdale junctions.
Police said the road would likely remain closed overnight. Diversions were currently in place via Nesting and Kergord.
A police accident investigation team is understood to be travelling to Lerwick on the ferry tonight after being unable to fly north.
