AlQa'dah 18, 1432, Oct 16, 2011, SPA - Hundreds of thousands gathered in cities across the world, sparked by the month-old Occupy Wall Street demonstrations in New York City. While masked anarchists created chaos in the centre of Rome setting fire to cars and even a police vehicle on Saturday, protests were peaceful elsewhere - in Hong Kong, Johannesburg, Tokyo, Manila, Zurich, Lisbon, London, Frankfurt and Berlin. Other cities of protests included Madrid, Vienna, Zurich and Santiago, according to a report of the German Press Agency "DPA".
