The Israel Defense Forces have found a way to block the tunnels Palestinians dig under the Gaza-Egypt border to smuggle in weapons by using a huge trench-digging machine, according to a military publication. The 100-ton behemoth would dig deep channels along the border route Israel patrols, exposing the tunnels, the soldiers' weekly "Bamahane" reports in its current edition. The new trenching machine, made U.S. company Trencor Inc., might provide at least an interim answer to the smuggling problem by neutralizing tunnels now in operation.
