Yossi Melman of the Jerusalem Post reports that the Israeli Defense Ministry is constructing a concrete barrier to run the length of the Gaza border and prevent Hamas from tunneling into Israel.
The 65-km. Gaza fence is to be completed by late 2018 or early 2019. The barrier will include heavy concrete slabs strengthened with iron rods and equipped with sensors that will be inserted dozens of meters underground.
Above ground, a 6 to 8 meter wire fence armed with sensors and cameras will be erected. The work will be accelerated this summer.
Israel believes there are currently 15 Hamas attack tunnels leading to Israel. When it has the intelligence and the opportunity it has bombed them, such as during retaliatory strikes after renegade groups in Gaza fire rockets into Israel.
