The IDF and the terrorist organizations in the Gaza Strip, led by Hamas and Islamic Jihad, are continuing to fight a “battle of wits” over the tunnels in the Gaza Strip. Israel has introduced a new high-tech tunnel detection system in the last year.


Earlier this month, the IDF uncovered a new tunnel in the Khan Yunis area. It penetrated Israel for more than 200 meters – the 15th tunnel the IDF has discovered in the past year.  

This tunnel was a kilometer in length, and it was connected to a network of combat tunnels inside Gaza. It was discovered several months ago, and IDF forces carried out various engineering works to ensure that it could no longer be used.

For the first time, it became clear that Hamas has learned some lessons, and it tried to scupper any chances of the IDF finding the tunnel by using certain materials and new building techniques.

Prime Minister Benjamin Netanyahu referred to the discovery of the tunnel, stating: “We are systematically dismantling Hamas’ tunneling capability. They need to understand that testing us is not worthwhile.”

Defense Minister Avigdor Liberman also stated that another step has been taken to destroy one of Hamas’ important strategic weapons and that the IDF’s goal is to destroy all of the tunnels by the end of 2018.

Sources in Gaza reckon that Hamas has 30 attack tunnels and several dozen more that are defensive, located among various parts of the Gaza Strip. They are used to conceal armaments such as rockets, mortars, and anti-tank missiles, which are intended for aiding terror organizations in times of war in the defense of Gaza against any possible incursion by IDF forces.

Why Is Hamas Still Building Tunnels?

According to Hamas sources, despite a noticeable improvement in the IDF’s technological capability to locate the tunnels, and in spite of the giant, deep land barrier that Israel has built around Gaza to stop the penetration of attack tunnels, the military wing of Hamas has not finished building these tunnels and is continuing to invest millions of dollars into their construction.

This raises the question of what logic is behind all of this. Why does Hamas continue to invest so many resources into this project, as it is clear that Israel is managing to deal with it successfully and even to defeat it?

The apparent answer is connected to the fact that there are still some attack tunnels that the IDF has not yet discovered, as well as new tunnels under construction using new methods and materials, and Hamas believes the IDF will have difficulty finding them.

Hamas has not yet given up the usage of tunnels as a strategic weapon against Israel.

This is expressed in an article published on the Internet site of the military wing of Hamas on October 15, 2018, under the headline, “Tunnels without Borders.”

The writer, Nasser Nasser, explains how Hamas perceives the situation:

“The issue can be viewed from two angles: One is tactical and the other strategic. Indeed, there is an important tactical loss to the resistance when it loses an important part of its strategic weapon in which it has invested so much of its children’s blood and sweat…. However, the second point is that it is a strategic success for the resistance, which emphasizes the continuing action of adhering to the principle of the tunnels as a weapon in a general sense, and the tunnels as a weapon outside our borders in a specific sense.”

Hamas admits that it has lost a vital part of its strategic weapon, but it assumes that the IDF will not find all of the attack tunnels it has built.

“Israel knows the existence of one attack tunnel is sufficient for the resistance to achieve strategic supremacy in any future conflict, so what if there is more than one attack tunnel, as Israel knows and has confirmed?” the author of the article writes.

These words relate to developments during October 2018 in the Gaza Strip, when Hamas ramped up the violence at the border in an attempt to abduct Israeli soldiers and infiltrate into the Israeli communities at the edge of Gaza through the tunnels. They also intended to kidnap civilians to be used as hostages and bargaining chips to force Israel to remove the embargo on the Gaza Strip, thereby achieving the objective of the “Return March” campaign, which has limped along for the past six months without any significant achievement.

Hamas sources state that the IDF has not fulfilled its declared mission to destroy all the tunnels originating from the Gaza Strip by the end of 2018. According to Hamas, the end of the year is approaching, and there are still active tunnels in the area.
