The New York Times is yet to report on this

"When Muslim worshipers showed up at the Bilal Mosque early Sunday morning, they found two pig's ears and a poster of the French flag stapled to the door; a pig's snout dangled from the doorknob. "White power" and "Sieg heil" were spray-painted on one side, they recalled, and "France for the French" on the other." (thanks Dina)
