The UN decided that Jerusalem (and Bethlehem) would be an international city, while 100,000 Jews (2,500 of the Old City) suffered an Arab blockade. Deir Yassin, a village located in a hill at the entrance of Jerusalem, was used to attack the Jewish aid convoys. The Jewish leadership approved the attack against Deir Yassin (Apr/9/1948). David Shaltiel, commander of the Hagana, wrote to the leaders of Irgun-Lehi: “I learned that you are planning to attack Deir Yassin. I want to point out that capturing this position is a stage of our general plan. I have no objection regarding the operation, as long as you are able to occupy the village”. One hundred and thirty-two soldiers of Irgun-Lehi attacked tens of armed Arabs hiding among 750 civilians. Many combatants, among them Iraqi soldiers, were disguised as women to shoot against the Jewish soldiers. The Irgun-Lehi forces tried to warn the civilians that they were attacking, to try to scare them away, with a truck and speakers. Apparently, the truck did not reach the area and probably was not heard. On the day of the attack, at 9:30, five hours after the fire started, Lehi evacuated 40 elders, women and children and took them to a base in Sheih Bader- Why did they save them if they were planning a massacre? A study of the Palestinian University Bir Zeit, based on Arab testimonials, affirms that 107 civilians died and 12 wounded, besides 13 “combatants”. Four Jews died. The Jewish authorities rejected the events of Deir Yassin and used them to discredit their ideological rivals. The Arabs exaggerated the events so the neighboring countries would send more forces against the Jews. The events of Deir Yassin convinced many Arab-Palestinians that a massacre actually occurred, and they decided to flee the combat areas.
