What's the Israel-Palestinian conflict about? The origin of wars explained

The fighting between Israel and Hamas, which launched a surprise attack on Saturday, is the latest in seven decades of war and conflict between Israelis and Palestinians that has drawn in outside powers and destabilised the wider Middle East.

The conflict pits Israeli demands for security in what it has long regarded as a hostile region against Palestinian aspirations for a state of their own.

Israel's founding father David Ben-Gurion proclaimed the modern State of Israel on May 14, 1948, establishing a safe-haven for Jews fleeing persecution and seeking a national home on land to which they cite deep ties over generations.

Palestinians lament Israel's creation as the Nakba, or catastrophe, that resulted in their dispossession and blocked their dreams of statehood.

In the war that followed, some 700,000 Palestinians, half the Arab population of what was British-ruled Palestine, fled or were driven from their homes, ending up in Jordan, Lebanon and Syria as well as in Gaza, the West Bank and East Jerusalem.
