Palestinians call this the Nakba, or catastrophe, as hundreds of thousands of Palestinians fled.
In 1967, in what’s known as the Six-Day War, Israel seizes the West Bank, the Gaza Strip, and the Golan Heights. Israel then went on to occupy thousands of kilometres of Palestinian territory, which the UN says is illegal.
Conditions for Gazans under the blockade are tough.
Hamas, which has a militant wing and a political arm, won democratic elections in 2006, but wouldn’t renounce violence against Israel and was isolated by the international community.
