 In September 2015, a Palestinian official said that only 200,000 Palestinian refugees were left in Syria, with 100,000 Palestinian refugees from Syria in Europe and the remainder in other Arab countries.An estimated 240,000 Palestinians are living in Saudi Arabia.They are not allowed to hold or even apply for Saudi citizenship, because of Arab League instructions barring the Arab states from granting them citizenship; the only other alternative for them is to marry a Saudi national.
