Hundreds of French Muslims held Saturday, March 6, a silent demonstration protesting two arson attacks on mosques in southeastern France a day earlier. The first fire in the city of Seynod engulfed an entire 800-square meter prayer hall, the pulpit and the library, French Le Monde daily reported. The second seriously damaged the heating system of a mosque in the city of Annecy before fire fighters got the situation under control. Security sources said the arson attacks were likely plotted by right-wing extremists, who harbor hatred towards the Muslim community in France . There were no immediate claims of responsibility.
