The Arab sector in Israel has promised that its commemoration today of the Arab riots of two years ago will not be violent - but large Israel Police contingents are deployed outside Arab areas just in case. Thirteen Arabs were killed during several days of anti-Jewish rioting across the Galilee. Marches will take place today in Nazareth, Um el Fahm, Kafr Kana, Jit, Arabeh, and Sakhnin.
