Source of gas-rig leak is found

The owners of a North Sea gas rig have found the source of a leak that forced hundreds of workers to be evacuated.

Oil company Total said the gas is coming from a rock formation 4,000m below the seabed before escaping from a leak on the platform roughly 25m above sea level.

Total is examining ways to block the leak, though it could take months. Any risk of explosion is said to be minimal.
