The United Nations General Assembly, the United Nations Security Council and the International Court of Justice have all said that Israeli settlements on the West Bank violate the Fourth Geneva Convention.
Israel captured the West Bank from Jordan in the 1967 war and has occupied the territory ever since. The Fourth Geneva Convention, ratified by 192 nations in the aftermath of World War II, says that an occupying power “shall not deport or transfer parts of its own civilian population into the territory it occupies.”
