The head of the IDF Southern Command warned Hamas terrorists that border-crossing attack tunnels were “a death trap for you,” in a video released Sunday after the military said it destroyed one such tunnel.
“Any tunnel that is discovered will be destroyed. We won’t hesitate to act in order to defend Israeli civilians,” said Maj. Gen. Eyal Zamir.
Zamir accused Hamas of “serially violating Israeli sovereignty,” and warned that continuing to do so risked “escalation” and threatened the Gaza Strip’s civilian population.
Addressing Hamas operatives, the general added: “I’ve warned the enemy and I’ll warn them again: Anyone who goes into a tunnel, endangers himself. These terror tunnels are a death trap for you.”
The general said that Israeli soldiers had entered deep into the tunnel, which stretched more than a kilometer from the Gaza Strip into Israeli territory.
“After our forces conducted an operation in the depths of the tunnel, we destroyed the tunnel, and it no longer presents a threat,” he said. The tunnel was discovered weeks ago.
Zamir and other Israeli officials, including Defense Minister Avigdor Liberman, have indicated that Israel would be able to eliminate the threat posed by attack tunnels, with a host of new technologies and techniques that were developed over the past three years.
“I hope that in the coming months the threat of the tunnels to residents of the Gaza periphery will become a thing of the past,” said Liberman on Sunday.
On Sunday, the IDF destroyed the attack tunnel using an undisclosed new technique that did not include the types of explosives used in the past, the army said.
The military said the kilometer-long tunnel was constructed by the Hamas terrorist group. It began in the Gazan city of Khan Younis and extended “hundreds of meters” inside Israeli territory. Israel demolished another cross-border tunnel, which was being dug by the Palestinian Islamic Jihad terror group, six weeks ago.
IDF spokesperson Lt. Col. Jonathan Conricus would not specify where exactly the newly destroyed tunnel was located in Israel, but said it ended in open farmland, approximately one kilometer (0.6 miles) from the nearest Israeli community.
The decision to destroy it was made several weeks ago. According to the officer, some of the closures set up around the Gaza Strip in the past month were connected to the tunnel discovery, while others were put in place for fear that terrorist groups would try to carry out sniper and anti-tank missile attacks on Israeli civilians who got too close to the area.
The spokesman noted that the tunnel did not pose an immediate threat to Israeli civilians and that it did not have an exit point at the time of the destruction.
He said the tunnel appeared to be a “very substantial” one for Hamas, “based on the level of detail.”
Conricus would not say what aspects of the tunnel specifically made the military believe that it belonged to Hamas, though photos from inside it showed a similar construction to the group’s tunnels that were found during the 2014 Gaza war, notably the assembly line produced concrete linings with a curved roof.
He added that the army holds “Hamas responsible twice — once, because it is responsible for any aggressive action coming from the Gaza Strip, and twice, because this was a Hamas terror tunnel.”
On October 30, the IDF blew up an attack tunnel belonging to the Palestinian Islamic Jihad group. In the blast and its aftermath, some 14 terrorists were killed, including two senior commanders and five who were digging inside Israeli territory at the time of the demolition.
In response to October’s tunnel demolition, Islamic Jihad vowed to avenge its operatives. A month later the group shelled an army post northeast of the Gaza Strip, which resulted in some equipment damage, but no Israeli injuries.
In this weekend’s blast, no Palestinians were reported killed, Conricus said.
However, he said the army made no such promises for the future.
The officer said the military did not see a connection between the tunnel demolition and ongoing, low-level protests in the Gaza Strip and West Bank, which Hamas is actively encouraging, against US President Donald Trump’s recognition of Jerusalem as Israel’s capital.
“We see these as separate events,” Conricus said. “There is no direct link, other than that the Hamas terrorist group is behind both of them.”
He credited the discovery of the tunnel to a “new system that the IDF now has,” which is the result of collaboration between various engineering, intelligence and ground forces units. “I am confident there will be more achievements in the future,” he said of the system.
The army would not elaborate on the nature of the new technique used to destroy the tunnel.
The military is currently constructing an underground barrier around the Gaza Strip that is meant to both prevent future attack tunnels and discover ones already constructed.
Military analysts suspect that, in light of the new barrier, Hamas is focusing more of its attention on developing an underground tunnel network within the Gaza Strip, as opposed to border-crossing tunnels.
The new underground barrier, which is estimated to cost upwards of NIS 3 billion ($851 million), is being built inside Israeli territory. The current metal fence surrounding the Strip, which lies exactly on the border, will remain in place while the new fence is built a few dozen meters inside Israel.
In order to construct the underground barrier, workers are using a German hydromill, a powerful piece of drilling equipment that cuts deep, narrow trenches into the earth.
In addition to opening up the ground where the barrier will be constructed, the hydromill is expected to expose any previously undiscovered or newly dug Hamas tunnels that enter Israeli territory.
The space left behind by the hydromill — and any Hamas tunnels that get in the way — is then filled with a substance known as bentonite, a type of absorbent clay that expands when it touches water.
This is meant to prevent the trenches from collapsing, but also has the additional benefit of indicating the presence of a tunnel, as the bentonite would quickly drain into it.
Workers then pour regular concrete into the trench. Metal cages with sensors attached are then lowered into the concrete for additional support.
In July 2014, Israel launched Operation Protective Edge in response to rocket fire from Gaza. During the 50-day campaign, the IDF destroyed some 14 tunnels that entered Israeli territory, along with 18 internal tunnels, and depleted Hamas’s weapons stores.
In the more than three years since the operation, the army has revealed that it found and destroyed at least four attack tunnels entering Israeli territory from the Gaza Strip, in April and May 2016, and in October and now December 2017.
In the time since the 2014 war, on average between one and two rockets have been fired from Gaza into Israel each month, including several that were fired on Friday night, hitting a kindergarten and an open street in the southern town of Sderot, and causing damage but no injuries.
Those rockets have been fired by fringe Salafist groups, not by Hamas, which took control of the Strip in 2007 and has ruled the coastal enclave ever since. That fact is generally credited to Hamas trying to maintain the relative calm so that it can use that time to better prepare for a future conflict with Israel.
