Anti-tunnel barrier along Israel-Gaza Strip border (original) (raw)

The anti-tunnel barrier along Israel-Gaza Strip border (sometimes referred to as the smart wall on the Israel-Gaza Strip border) is an underground slurry wall constructed by Israel along the entire 40 kilometers (25 mi) length of the Israel-Gaza Strip border to prevent anti-Israel militant groups operating in the Gaza Strip, especially Hamas (which Israel, along with other countries, regards as a terrorist group), from infiltration into Israel by digging tunnels under the Gaza–Israel barrier. The project includes excavation to classified depths, and the construction of thick concrete walls combined with sensors and alarm devices.
