The key word here is ”unhappy worshiper”.
French mosque vandalized with anti-Islam graffiti
PARIS – Agence France-Presse
The attack was discovered by worshippers arriving for morning prayers at the mosque in Ozoir-La-Ferriere, a small town 35 kilometers east of Paris.
Photographs of the mosque show at least two swastikas painted on the facade, as well as an explicit anti-Islam slogan and “Long Live Gaul,” the ancient Roman-era name for France. Police were investigating the incident.
In the eastern city of Besançon, two mosques were also vandalized with a Star of David – commonly used by the Nazis to identify Jews.
Sources close to the inquiry, however, cautioned that the vandalism was not necessarily triggered by anti-Islam sentiment and said investigators were looking at several leads, including whether it was carried out by an unhappy worshipper.
