The Palio dei Normanni is an annual event held in the city of Piazza Armerina in Sicily that commemorates the 11th century Norman conquest of the island from the Saracens. It typically features costumed parades and re-enactments of the battles.
A graphic that was being used to publicise the event showed a fire behind a mosque and a knight wearing a modern-style helmet. As soon as this was published on the Facebook page of the organisers, they started to come under pressure from the local newspaper and prefect. The newspaper claimed that the image showed a mosque on fire, pointed out that ISIS propaganda had shown the Vatican on fire and argued that the image put visitors in jeopardy because of the possibility of a Muslim revenge attack. It insisted that the graphic could encourage violence against Muslims "in an area where anti-Arab stories are still told".
The organisers then changed the graphic to the one shown below, claiming that the earlier version had only been a provisional draft copy.
