The Israeli–Palestinian conflict (Hebrew: הסכסוך הישראלי-פלסטיני‎, translit. Ha'Sikhsukh Ha'Yisraeli-Falestini; Arabic: النزاع-الفلسطيني الإسرائيلي‎, translit. al-Niza'a al-Filastini-al-Israili) is the ongoing struggle between Israelis and Palestinians that began in the mid-20th century.[3] The origins to the conflict can be traced back to Jewish immigration, and sectarian conflict in Mandatory Palestine between Jews and Arabs.[4] It has been referred to as the world's "most intractable conflict", with the ongoing Israeli occupation of the West Bank and the Gaza Strip reaching 51 years.[5][6][7]
