The conflict began on 29 October 1956 . At about 3:00 pm , Israeli Air Force Mustangs launched a series of attacks on Egyptian positions all over the Sinai . Because Israeli intelligence expected Jordan to enter the war on Egypt 's side , Israeli soldiers were stationed along the Israeli-Jordanian frontier . The Israel Border Police militarized the Israel-Jordan border , including the Green Line with the West Bank , during the first few hours of the war . Israeli-Arab villages along the Jordanian border were placed under curfew . This resulted in the killings of 48 civilians in the Arab village of Kafr Qasim in an event known as the Kafr Qasim massacre . The border policemen involved in the killings were later tried and imprisoned , with an Israeli court finding that the order to shoot civilians was " blatantly illegal " . This event had major effects on Israeli law relating to the ethics in war and more subtle effects on the legal status of Arab citizens of Israel , who at the time were regarded as a fifth column
