With newspaper advertisements and around 1,200 billboard posters, authorities of the French capital city Paris will start a campaign against racism and anti-Semitism today. The billboards and ads will show the message, "Paris says no to anti-Semitism, racism and all forms of discrimination" in large type on a blue background, city hall officials said. As part of other new security measures in Paris, surveillance cameras are to be installed at Jewish schools, synagogues and other sites. Mayor Bertrand Delanoë has also called for debates in schools, which resumes on Thursday. France, which has the largest populations of Jews and Muslims in western Europe, has suffered a series of anti-Semitic acts recently.
