Yes, a walk out by ATC staff has led to the suspension of all air traffic in Norway. Our flight FI320 ex KEF was already enroute and has had to divert to BGO (via ATC who advised to divert and contact BGO tower radio) and is waiting there with pax on board for decision whether to terminate the flight there and return empty or if hours permit to wait and continue the flight. Fortunately they had return catering onboard so lunch is being served without too much hassle, the crew were a bit upset about the coffee though.
