An open-air prison is a term used to describe a situation where a group of people is confined to a specific area, often with limited access to the outside world. The term is often used to describe the situation in the Gaza Strip, where Israel has imposed a land, sea, and air blockade since 2007, citing security concerns. The blockade has resulted in severe restrictions on the movement of people and goods, leading to a humanitarian crisis in the region. Many Palestinians and humanitarian actors describe Gaza as the worlds largest open-air prison, where 1.94 million Palestinians live behind a blockade and are refused access to the other occupied Palestinian areas and the rest of the world. In contrast, an open prison is a jail in which prisoners are trusted to complete their sentences with minimal supervision and perimeter security and are often not locked up in their prison cells. Prisoners may be permitted to take up employment while serving their sentence, and open prisons are often part of a rehabilitation plan for prisoners moved from closed prisons.
