The Hebron massacre, in which 67 Jews are killed, is part of a larger wave of riots and clashes between Arabs and Jews. The riots begins over an incident at the Western Wall, which set off Arab mobs and quickly escalates into violence. The British investigation begins an inquiry led by Sir Walter Shaw. The death of so many Jews in Hebron (isolated as it was from other Jewish enclaves) forces the Zionists to buy land in contiguous blocks in valley and coastal regions and not in the hill regions of Palestine.
