evidence: The land which would become Israel was for centuries part of the Turkish-ruled Ottoman Empire. After World War One and the collapse of the empire, territory known as Palestine - the portion of which west of the River Jordan was also known as the land of Israel by Jews - was marked out and assigned to Britain to administer by the victorious allied powers (soon after endorsed by the League of Nations). [...] Similarly, Israel has had a de facto border with Gaza since it pulled its troops and settlers out in 2005, but Gaza and the West Bank are considered a single occupied entity by the UN, and the official borders have not yet been determined. The final status and contours of the West Bank, Gaza and East Jerusalem are meant to be decided in negotiations between Israel and the Palestinians living there under Israeli occupation, but decades of on-off talks have so far proved fruitless.
