At least four Israeli cities, including the commercial capital Tel Aviv, have banned Arab laborers from their schools, struggling to calm public fears fueled by the worst surge of Palestinian street attacks in years.
Citing security concerns, Tel Aviv and the nearby cities of Rehovot and Hod Hasharon avoided using the word "Arab" in announcing on their websites and emails to residents that maintenance workers and cleaners - many of whom are Arabs - would not be allowed into schools.
Another city, Modiin-Maccabim-Reut, midway between Tel Aviv and Jerusalem, said "minority members" - a term Jews in Israel often use for Arab citizens who make up 20 percent of the population of eight million - would be banned from working in its schools.
Israel, which has poured hundreds of troops into its cities and set up roadblocks in Palestinian neighborhoods of East Jerusalem, said that on Saturday four Palestinians were shot dead and a fifth seriously injured in thwarted knife attacks.
