Most recently the French National Assembly passed a bill criminalizing the denial of (Christian) Armenian genocide done by (Islamic) Ottoman Turks during 1915-1916. Turkey is very angry about this move.
See the BBC News Europe story which quotes Turkish Prime Minister Recep Tayyip Erdogan as saying:
This is politics based on racism, discrimination and xenophobia. This is using Turkophobia and Islamophobia to gain votes, and it raises concerns regarding these issues not only in France but all Europe.Now Turkey has taken measures against France.
