Scottish First Minister Alex Salmond has warned against speculation about the cause of what he described as the "tragic and serious" helicopter accident in which four people died on Friday off Shetland.

Mr Salmond said it was right that the North Sea oil industry had agreed to ground all models of Super Puma helicopter until it was certain they were safe.

He added that air accident investigators should be given time to carry out their work.
