Déclaration de guerre - Prières musulmanes en plein Rome (22 avril 2011)
Those illegal Muslim prayers took place on the Piazza Venezia, in front of the national monument dedicated to Vittorio-Emanuele II, and, more precisely, in front of the "Altar to the homeland"
Therefore, those prayers were a declaration of war to the Italian homeland.
Moreover, this Friday, April 22nd, was the Good Friday : therefore, those prayers were a declaration of war to all the Christians too.
