An operation to remove an unexploded World War II mine at a pipeline in the North Sea is under way.

The mine was discovered in 1993, at the Far North Liquids and Associated Gas System (Flags) pipeline, about 62 miles off Aberdeen.

Shell said an operation was under way, after risk assessments and approval.

Shell said: "Our priority is working to ensure a safe outcome, and we will provide more information once we have completed the operation."
