My Lords, there is a significant problem following the incidents at the weekend and it will affect some NATO operations. Fortunately, most of our supplies go by different routes but there is pressure on the airbridge to deliver them. There is already a NATO contract with civilian operators to provide airlift for non-personnel to areas in Afghanistan. That has proved successful and extremely helpful and we continue to keep it under review. It is not suitable for troop movements but it is suitable for freight and it has been a significant help.
