Israeli Army’s Plan to Flood Hamas Tunnels Fails

The Israeli media on Saturday renewed talk about the Atlantis system, a significant engineering and technological breakthrough that was supposed to take out the Hamas tunnels and to kill senior Hamas officials, by pumping in seawater at high intensity.

The system was supposed to be the game changer, a new, relatively quick and lethal solution to one of the more complex fronts in the Gaza Strip.

But Israel started by adopting an old and unsuitable plan, continued by ignoring professional advice and the possible danger to the abductees – and ended quietly a few months later, anyone saying whether it achieved anything at all.

Haaretz surveys profiled the Atlantis project – a predictable military failure which no one stopped until it was too late.

“But about half a year after this system was revealed to the public, it turns out that Atlantis is lost; it's no longer in use, and nobody in the army can say what benefit, if any, was gained from this expensive project,” the newspaper wrote.

A Haaretz investigation – based on discussions with a series of different sources, who are closely involved in the development and operation of the system, as well as documents and minutes from closed discussions, in which senior officers and professionals participated– reveals a large number of screw-ups in the way it was handled by the army, and provides a profile of a failure foretold.

For example, it turns out that the system started to operate even before the necessary opinions requested by the army were given; that behind the accelerated activity there was a great deal of pressure imposed from above by the head of Southern Command, Maj. Gen. Yaron Finkelman; and that it was activated while possibly endangering Israelis who were alive when abducted to the Strip.
“The system was activated in at least one central Hamas tunnel that was clearly used by the organization during various stages of the war,” said a defense source who was deeply involved in project Atlantis. “And it's very likely that there were hostages there who served as a human shield.”

The question of how it happened that a project described by the Israeli Army as a “tie breaker” turned into a steadily growing failure has a complex answer.

One of the main causes is the backdrop, Haaretz said. During the first days of the war, says a defense source, “The achievements on the ground against Hamas officials were insignificant. Most of the Hamas forces, mainly the military arm, entered the tunnels and that created pressure on the senior Israeli Army command.”

That's why, says another source who spoke to Haaretz, Finkelman demanded solutions; ways of striking at Hamas activists in the tunnels. “There was frustration because during those stages the forces didn't really think that we'd start to enter all the tunnels,” recalls the source.

“They also began to realize the dimensions of the tunnels that Military Intelligence didn't know about.”

At that time, the Israeli Army was still learning about the tunnels they encountered in the Strip and their scope hundreds of kilometers.

“The army,” he adds, “found itself on the ground realizing that Hamas was below the ground and it had no solution for removing them from there.”

It was actually the renewal of a contingency plan that was proposed in the ground forces years before Finkelman assumed his position.

At the time the purpose was to deal with a different type of tunnel. Its chances of success in dealing with the tunnels that the army found in the Strip beginning on October 7 were low.

But according to defense sources who spoke to Haaretz, Finkelman gave a green light to taking the old plan and adapting it to the new situation.
After the plan received the necessary permits, the Army turned to the Israel Water Authority for assistance.

The authority hastened to mobilize for the mission and formed two groups of civilian experts in several fields. One group was placed in charge of pumping the water into the tunnels, the second was asked to study the subject of water loss through the walls of a tunnel. Both groups got started.
But the Israeli Army didn't wait for the conclusions, and already at this point they embarked on the next stage.

The Southern Command's 162nd division was chosen as the contractor of the operation, and infrastructure work was assigned to the fighters of the Shayetet 13 naval commandos, which for several weeks became a pipeline unit.

The main goal: joining pipes and deploying them in the combat area.

“For a month and a half the Israeli army neutralized an entire division,” says one of the commanders who took part in the project. “It assigned combat soldiers to plumbing jobs and guarding pipes, throughout the Strip, when it had no idea whether the project had any operational feasibility.”

He said, “The Army had no way of knowing whether the system was working, what had happened in the tunnels, what the situation was of the terrorists inside and whether there were hostages who were harmed as a result of the water. To this moment it isn't clear what damage was caused in the tunnels, if any. They simply don't know anything.”

According to a document issued by the experts on the subject, about three weeks after Atlantis began to operate, “The activation wasn't carried out according to the recommendations of the professionals. The pumping wasn't done according to the combat theory that was developed, no findings were gathered and they didn't take the measurements that were described.”

The experts were angry throughout the period. “There was a disconnect between the sources in the field and the accompanying unit on the one hand and the experts who planned the method of operation on the other,” they said.

And in fact, at that time, say professionals, the military lacked the requisite information and data about the tunnels, certainly not how to flood them in a way that would harm those inside or cause them to flee to the surface.

In the course of the project, the Water Authority investigators had a chance to be exposed to the study prepared by a Hamas activist who served in the tunnel system in the past 10 years. Along with his statement that the tunnels became the main system prepared by the organization for a military confrontation with Israel, he described how they were constructed and the logic behind them.



Gaza Ceasefire Enters Phase Two Despite Unresolved Issues

Gaza Ceasefire Enters Phase Two Despite Unresolved Issues

A US-backed plan to end the war in Gaza has entered its second phase despite unresolved disputes between Israel and Hamas over alleged ceasefire violations and issues unaddressed in the first stage.

The most contentious questions remain Hamas's refusal to publicly commit to full disarmament, a non-negotiable demand from Israel, and Israel's lack of clarity over whether it will fully withdraw its forces from Gaza.

The creation of a Palestinian technocratic committee, announced on Wednesday, is intended to manage day-to-day governance in post-war Gaza, but it leaves unresolved broader political and security questions.

Below is a breakdown of developments from phase one to the newly launched second stage.

- Gains and gaps in phase one -

The first phase of the plan, part of a 20-point proposal unveiled by US President Donald Trump, began on October 10 and aimed primarily to stop the fighting in the Gaza Strip, allow in aid and secure the return of all remaining living and deceased hostages held by Hamas and allied Palestinian armed groups.

All hostages have since been returned, except for the remains of one Israeli, Ran Gvili.

Israel has accused Hamas of delaying the handover of Gvili's body, while Hamas has said widespread destruction in Gaza made locating the remains difficult.

Gvili's family had urged mediators to delay the transition to phase two.

"Moving on breaks my heart. Have we given up? Ran did not give up on anyone," his sister, Shira Gvili, said after mediators announced the move.

Israeli Prime Minister Benjamin Netanyahu said efforts to recover Gvili's remains would continue but has not publicly commented on the launch of phase two.

Hamas has accused Israel of repeated ceasefire violations, including air strikes, firing on civilians and advancing the so-called "Yellow Line," an informal boundary separating areas under Israeli military control from those under Hamas authority.

Gaza's Hamas-run health ministry said Israeli forces had killed 451 people since the ceasefire took effect.

Israel's military said it had targeted suspected fighters who crossed into restricted zones near the Yellow Line, adding that three Israeli soldiers were also killed by fighters during the same period.

Aid agencies say Israel has not allowed the volume of humanitarian assistance envisaged under phase one, a claim Israel rejects.

Gaza, whose borders and access points remain under Israeli control, continues to face severe shortages of food, clean water, medicine and fuel.

Israel and the United Nations have repeatedly disputed figures on the number of aid trucks permitted to enter the Palestinian territory.

- Disarmament, governance in phase two -

Under the second phase, Gaza is to be administered by a 15-member Palestinian technocratic committee operating under the supervision of a so-called "Board of Peace," to be chaired by Trump.

"The ball is now in the court of the mediators, the American guarantor and the international community to empower the committee," Bassem Naim, a senior Hamas leader, said in a statement on Thursday.

Mediators Egypt, Türkiye and Qatar said Ali Shaath, a former deputy minister in the Ramallah-based Palestinian Authority, had been appointed to lead the committee.

Shaath, in an interview, said the committee would rely on "brains rather than weapons" and would not coordinate with armed groups.

US Middle East envoy Steve Witkoff said phase two aims for the "full demilitarization and reconstruction of Gaza," including the disarmament of all unauthorized armed factions.

Witkoff said Washington expected Hamas to fulfill its remaining obligations, including the return of Gvili's body, warning that failure to do so would bring "serious consequences".

The plan also calls for the deployment of an International Stabilization Force to help secure Gaza and train vetted Palestinian police units.

For Palestinians, the central issue remains Israel's full military withdrawal from Gaza - a step included in the framework but for which no detailed timetable has been announced.

With fundamental disagreements persisting over disarmament, withdrawal and governance, diplomats say the success of phase two will depend on sustained pressure from mediators and whether both sides are willing - or able - to move beyond long-standing red lines.


Lebanon Charges Four Accused of Kidnapping for Israel’s Mossad

Four people accused of a kidnapping in Lebanon for Israel's Mossad spy agency last month have been charged, a judicial official said on Thursday, after a retired security officer whose brother was linked to an Israeli airman's disappearance went missing.

Israel has apprehended suspects in Lebanon before and Mossad is accused of regularly attempting to contact Lebanese people to facilitate its operations, while Lebanon has arrested dozens of people on suspicion of collaborating with Israel over the years.

Lebanese authorities believe the agency known for espionage operations outside of Israel's borders was behind the disappearance of retired security officer Ahmad Shukr last month.

Shukr, whose brother Hassan is suspected of involvement in the 1986 capture of Israeli air force navigator Ron Arad, disappeared in the Bekaa region of eastern Lebanon.

Authorities have arrested and charged one Lebanese man and charged three more who remain at large.

The four were charged with "communicating with and working for Mossad within Lebanon in exchange for money, and carrying out the kidnapping of Ahmad Shukr", a judicial official told AFP on condition of anonymity.

The three are "a Lebanese woman, a Lebanese-French man, and a Syrian-Swedish man," the official said.

The Israeli airman Ron Arad, whose plane went down in southern Lebanon during the country's civil war between 1975 and 1990, is now presumed dead and his remains were never returned.

Hassan Shukr was killed in 1988 in a battle between Israeli forces and local fighters, including from the Iran-backed Hezbollah group, a source close to the family told AFP last month, requesting anonymity.

Two Israeli airstrikes killed five people, including a 16-year-old, in Deir al-Balah on Thursday, said local health authorities.

The Israeli military did not immediately respond to a Reuters request for comment on the incident.

It was not immediately clear what triggered the attacks, which were in areas outside the control of Israeli forces in the strip.

More than 400 Palestinians ‌and three Israeli ‌soldiers have been reported ‌killed ⁠since a ‌fragile ceasefire took effect in October.

Israel has razed buildings and ordered residents out of more than half of Gaza where its troops remain. Nearly all of the territory's more than 2 million people now live in ⁠makeshift homes or damaged buildings in a sliver of ‌territory where Israeli troops have withdrawn ‍and Hamas has ‍reasserted control.

The United Nations children agency ‍said on Tuesday that over 100 children have been killed in Gaza since the ceasefire, including victims of drone and quadcopter attacks.

Israel and Hamas have traded blame for violations of the ceasefire and remain far apart ⁠from each other on key issues, despite the United States announcing the second phase of the ceasefire on Wednesday.

Israel launched its operations in Gaza in the wake of an attack by Hamas-led fighters on October, 2023 which killed 1,200 people, according to Israeli tallies. Israel's assault has killed 71,000 people, according to health authorities in the strip, ‌and left much of Gaza in ruins.
