Closures are imposed by the
Israeli army by and large on Palestinians in order to restrict movement in the Occupied
Palestinian Territories.These restrictions include physical structures such as military checkpoints, and Israeli-enforced orders such as closed military zones and curfews.
Israel says that closures are necessary to prevent attacks against Israeli citizens, while Palestinians point to the illegality and discrimination of such closures and their damaging effect on normal life and movement. See "
West Bank Closure count and analysis, occupied Palestinian territory," United Nations Office of the Coordination of Humanitarian Affairs, Sept 2006.
