Restrictions on the movement of Palestinians in the Israeli-occupied territories by Israel is an issue in the Israeli–Palestinian conflict. According to B'Tselem, following the 1967 war, the occupied territories were proclaimed closed military zones. In 1972, general exit orders were issued allowing residents of those territories to move freely between the West Bank, Israel and the Gaza Strip. Following the First Intifada by 1991, the general exit orders were revoked, and personal exit permits were required. According to B'Tselem, a measure of overall closure of the territories was enacted for the first time in 1993, and would result in total closures following rises in Palestinian political violence.
