A mosque in the French city of Limoges has been desecrated by having excrement smeared on its doors, Interior Minister Manuel Valls said Wednesday in a statement condemning the incident. The attack occurred overnight following reports of mob violence in Egypt and Libya involving Islamists angered by a US-made film said to insult the Prophet Mohammed (PBUH). There was no immediate indication however that the desecration was linked to the unrest over the film. Local police said the mosque doors had been daubed with neo-Nazi graffiti at the end of July. They also said it was possible the attack was of a random nature, as a local restaurant unconnected to the Muslim community was subject to a similar attack earlier this month. Unlike many mosques in France, the Limoges centre is immediately recognizable as an Islamic place of worship because of its minaret.
