Vandals ripped up some 90 Muslim graves in an Austrian cemetery and defaced the headstones with black spray paint, Police said Monday, DPA reported. The Islamic community in Linz, the nearest major city, said the images left by the assailants included Jewish symbols, but that it suspected the culprits were neo-Nazis, not Jews, Austria's APA news Agency reported. "We are deeply shocked, " the Islamic community said in a Statement. Last week, a far-right group's sticker was found at the cemetery's entrance. Police launched an investigation into the desecrations, which apparently happened over the weekend. There were no immediate suspects. The Muslim grave sites are part of the town cemetery in Traun, outside Linz. The first Muslims were buried there in 2002. Muslims make up more than 4 per cent of Austria's 8.3 million people, or about 400,000 people. Most have Turkish or Bosnian roots.
