Speaking of Eurovision, there was an incident last year in which Iceland’s band, Hatari, displayed scarves bearing the Palestinian flag while being broadcasted at the finals (which took place in Israel last year). Iceland was fined for this gesture because the organizers behind Eurovision have banned political gestures during the event: “participating broadcasters shall ensure all necessary steps are undertaken within their respective delegations and teams in order to make sure that the ESC shall in no case be politicized and/or instrumentalized.”
