In the Arab world, anti-Jewish rioters killed over 140 Jews in the 1945 Anti-Jewish Riots in Tripolitania. Following the start of the 1947–48 Civil War in Mandatory Palestine, a number of anti-Jewish events occurred throughout the Arab world, some of which have been described as pogroms. In 1947, half of Aleppo's 10,000 Jews left the city in the wake of the Aleppo riots, while other anti-Jewish riots took place in British Aden and the French Moroccan cities of Oujda and Jerada.
