An army plan to dig a moat along the border was dropped in 2005 after it became clear that it would likely be rejected by Israel's Attorney General, Menachem Mazuz, because it required the destruction of 3,000 more homes in Rafah.[13][14] Instead, the IDF started the building of a 7–9 meters high (about 20–30 feet) concrete wall along the border in a 60–100 meter (about 200–300 feet) wide security strip, equipped with electronic sensors and underground concrete barriers to prevent tunneling.[13]
