Israel unveils plans for 40-mile underground wall around Gaza

Israel unveiled its plans for a vast underground wall around Gaza on Thursday, which military officials said would once and for all stop Hamas burrowing attack tunnels into Israeli territory.

The £500 million subterranean concrete barrier will run for 40 miles along the entire Israeli-Gaza border and is the first underground border wall of its kind in the world.

It is intended to prevent Hamas and other Islamist militant groups from using tunnels to launch surprise attacks into southern Israel.
