Israeli settlements, also called Israeli colonies, are the civilian communities built by Israel throughout the Israeli-occupied territories. They are populated by Israeli citizens, almost exclusively of Jewish identity or ethnicity, and were built on lands occupied by Israel since the Six-Day War in 1967. The international community considers Israeli settlements to be illegal under international law, but Israel disputes this. The expansion of settlements often involves the confiscation of Palestinian land and resources, leading to displacement of Palestinian communities and creating a source of tension and conflict. Settlements are often protected by the Israeli military and are frequently flashpoints for violence against Palestinians. Further, the presence of settlements and Jewish-only bypass roads creates a fragmented Palestinian territory, seriously hindering economic development and freedom of movement for Palestinians.
