This is Qalqiliyaa, where 100,000 Palestinians live surrounded by an Israeli wall on three sides. The fourth side is controlled by a gate that can be closed by an Israeli soldier at any time.

The city has 4 main exits:
Nablus street exit: narrow, but is still open. It's a one lane per line street which has an Israeli checkpoint right on the outside of the city. This is the one where Israeli soldiers go and block for training.
Toulkarm street exit: has been blocked for +30 years. Only workers with permission can go, and only without cars.
Habla street exit: one lane per line street. Has a barrier which closes it at any given moment.
Habla alternative exit: fairly recently opened and can be closed at any given point.

The population is not allowed to grow as it could because the city is surrounded by the racial separation wall and therefore people are unable to expand. Furthermore, the northern parts of the city (on the left in this photo) are farmlands which farmers are only allowed to use for farming. They are not allowed to build houses there in their own lands. If they do, they are brought down quickly. The closest thing to a house they can build in these areas is a one story building where the roof can not be concrete and therefore you cannot build more stories if you want to.

The West Bank was occupied by Israel in 1967 and has been illegally annexed. The Palestinians are not citizens of Israel. They have no sovereignty. They have no rights. They are administed by an IDF Martial Law and adjuicated by Military Tribunals. This subjects them to a byzantine labyrinth of rules and regulations. Their land is confiscated and they are evicted to make way for Jewish Settlers. They are forced onto smaller and smaller plots of land isolated from one another like in this picture. The are assaulted by Jewish Settlers, their crops destroyed, their wells sealed with concrete, their movement tightly restricted, their economic development impeded.
