Israel Begins Building Underground Barrier Along Gaza Border

The IDF has begun building a 70 kilometer long subterranean barrier along the Gaza border.

The concrete barrier, which is expected to take years to build and cost NIS 2 billion, will go to depth of a few meters underground and include advanced tunneling detection systems in case Hamas tries to dig below the wall.

The hope is that the barrier will block Hamas's terror tunnels from crossing the border from Gaza, though Hamas has previously built tunnels that go dozens of meters underground into Israel.
