A fire was set in the church Saint-Pierre du Matroi in Orléans on the 25th of July. Sheet music was burned, furniture was damaged, and smears of graffiti were found on several walls, including one reading "Allahu Akbar." The fire brigade was able to intervene early enough to prevent further spread of the fire, thus preserving the support structure of the church. The police believe the fire was intentionally set.
