While Islamic antisemitism has increased in the wake of the Arab–Israeli conflict, there were riots against Jews in Middle Eastern countries prior to the foundation of Israel, including unrest in Casablanca, Shiraz and Fez in the 1910s, massacres in Jerusalem, Jaffa, Safed and Hebron in the 1920s, pogroms in Algeria, Turkey and Palestine in the 1930s, as well as attacks on the Jews of Iraq and Tunisia in the 1940s. As Palestinian Arab leader Amin al-Husseini decided to make an alliance with Hitler's Germany during World War II, 180 Jews were killed and 700 Jews were injured in the Nazi-inspired riots of 1941 which are known as the Farhud. Jews in the Middle East were also affected by the Holocaust. Most of North Africa came under Nazi control and many Jews were discriminated against and used as slaves until the Axis defeat. In 1945, hundreds of Jews were injured during violent demonstrations in Egypt and Jewish property was vandalized and looted. In November 1945, 130 Jews were killed during a pogrom in Tripoli. In December 1947, shortly after the UN Partition Plan, Arab rioting resulted in hundreds of Jewish casualties in Aleppo, including 75 dead. In Aden, 87 Jews were killed and 120 injured. A mob of Muslim sailors looted Jewish homes and shops in Manama. During 1948 there were further riots against Jews in Tripoli, Cairo, Oujda and Jerada. As the first Arab–Israeli War came to an end in 1949, a grenade attack against the Menarsha Synagogue of Damascus claimed a dozen lives and thirty injured. The 1967 Six-Day War led to further persecution against Jews in the Arab world, prompting an increase in the Jewish exodus that began after Israel was established. Over the following years, Jewish population in Arab countries decreased from 856,000 in 1948 to 25,870 in 2009 as a result of emigration, mostly to Israel.
