High Quality Content by WIKIPEDIA articles! The Philadelphi Route refers to a narrow strip of land, 14 km in length, situated along the border between Gaza Strip and Egypt. Under the provisions of the Israeli-Egyptian peace treaty of 1979, the buffer zone was controlled and patrolled by Israeli forces. After the 1995 Oslo Accords, Israel was allowed to retain the security corridor along the border. One purpose of the Philadelphi Route was to prevent the movement of illegal materials (including weapons, ammunition and illegal drugs) and people between Egypt and the Gaza Strip. Palestinians, in cooperation with some Egyptians, have built smuggling tunnels under the Philadelphi Route to move these into the Gaza Strip.
