Controversy has been re-ignited this week as a series of new ads containing quotes used by terrorists have appeared on San Francisco Muni buses. “Killing Jews is worship that draws us closer to Allah,” reads one of the ads, containing words attributed to the Hamas terrorist organization. "The mosques are our barracks, the domes our helmets, the minarets our bayonets and the faithful our soldiers," reads another, echoing the words of Turkish Prime Minister Recep Tayyip Erdogan.
