The maps in the links can be clicked on to magnify them. In the Israeli map, the red areas are separated by Israeli controlled areas, and also they are divided up by roads. If one looks at each red area, one can see a lot of roads snaking around and through it. Each of those roads separates the red area it is in into much smaller areas. Those roads are barriers to movement for the Palestinians. They are apartheid, Jewish-only roads that the Palestinians are not allowed to use or cross. The only way Palestinians can get from one side of one of those roads to the other side is to travel to the nearest checkpoint, and go through the arduous process of trying to be allowed to pass through. People often have to wait for hours or days to get through, and they are also often not allowed through at all. And each red area is also surrounded by Israeli controlled land that the Palestinians have to go through the same process to cross.
