Wikipedia The Deir Yassin massacre took place on April 9, 1948, when around 120 fighters from the Irgun and Lehi Zionist paramilitary groups attacked Deir Yassin near Jerusalem, a Palestinian-Arab village of roughly 600 people. The invasion occurred as Jewish militia sought to relieve the blockade of Jerusalem during the civil war that preceded the end of British rule in Palestine.Around 107 villagers, including women and children, were killed. Some were shot, while others died when hand grenades were thrown into their homes. Several were taken prisoner and may have been killed after being paraded through the streets of West Jerusalem, though accounts vary. News of the killings sparked terror within the Palestinian community, encouraging them to flee from their towns and villages in the face of Jewish troop advances, and it strengthened the resolve of Arab governments to intervene, which they did five weeks later by invading Palestine, following Israel's declaration of independence on May 14.
