Norwegian airports are being affected by a strike by the country's public sector workers. Security workers at airports joined the strike on Friday. Workers are striking over wages. The strike has also affected other sectors in Norway, with schools closing. Oil producers say that production continues, but reduced air traffic means that some workers will have to stay on oil platforms longer than planned.
