parts of Yemen, and among certain northern Arabian tribes such as the Ghassanids, Lakhmids, Taghlib, Banu Amela, Banu Judham, Tanukhids and Tayy. In the early Christian centuries, Arabia was sometimes known as Arabia heretica, due to its being "well known as a breeding-ground for heterodox interpretations of Christianity." Christians make up 5.5% of the population of Western Asia and North Africa. A sizeable share of those are Arab Christians proper, and affiliated Arabic-speaking populations of Copts and Maronites. In Lebanon, Christians number about 40.5% of the population. In Syria, Christians make up 10% of the population. In West Bank and in Gaza Strip, Christians make up 8% and 0.7% of the populations, respectively. In Egypt, Coptic Christians number about 10% of the population. In Iraq, Christians constitute 0.1% of the population. In Israel, Arab Christians constitute 2.1% (roughly 9% of the Arab population). Arab Christians make up 8% of the population of Jordan. Most North and South American Arabs are Christian, so are about half of the Arabs in Australia who come particularly from Lebanon, Syria and Palestine. One well known member of this religious and ethnic community is Saint Abo, martyr and the patron saint of Tbilisi, Georgia. Arab Christians also live in holy Christian cities such as Nazareth, Bethlehem and the Christian Quarter of the Old City of Jerusalem and many other villages with holy Christian sites.
