Israeli soldiers prepare to storm Hamas tunnels beneath Gaza to fight through a booby-trapped labyrinth longer than the London Underground

Because the battle intensifies across the al-Shifa Hospital in Gaza Metropolis — and the grim tally of useless civilians continues to rise — the women and men of the Israel Defence Forces (IDF) are decided to root out their enemy.

Beneath the sprawling advanced, insists Israeli intelligence, lies a headquarters for Hamas, a nexus for the huge community of tunnels that spans all of Gaza.

And it’s someplace on this subterranean world that tons of of Israeli hostages have been held by their terrorist captors for 40 days and nights.

Certainly, the community is estimated to run to a complete of 300 miles and is so in depth it has been described as a ‘metro system’ that’s larger than the London Underground.

The 85-year-old Israeli hostage Yocheved Lifshitz, who was launched final month, revealed that Hamas had hidden her and different hostages in a tunnel system that ‘seemed like a spider’s internet’.

After I was final in Gaza in 2016, the affect of those tunnels was all over the place. 1000’s of individuals have discovered work in them and tens of hundreds extra, from drivers to shopkeepers, have benefited from the work they supplied.

It’s a disconcerting feeling, strolling round with the data that, beneath your ft, a terrorist military is burrowing away, smuggling items and plotting assaults.

The tunnels are deadly: the lifeblood of Hamas’s battle towards Israel, they’re a lattice of terror. And so they want gas and oxygen to perform.

One of many causes Israel has been so reluctant to permit humanitarian support into Gaza is the actual fact it is aware of Hamas is siphoning off desperately wanted provides to maintain the tunnels operational.

Certainly, Hamas has huge stockpiles of gas to gentle its tunnels, whereas bizarre Gazans are in hospitals with barely sufficient electrical energy to energy the tools.

On Monday, the Israeli navy launched photographs of a cache of weapons it mentioned had been present in Hamas tunnels beneath the al-Rantisi youngsters’s hospital, a mile and a half from al-Shifa. Additionally they discovered a bike, thought to have been used to move hostages seized on October 7.

One room contained a chair with girls’s clothes and a rope subsequent to it, suggesting it had been used to restrain the captives. Close by was a child bottle and nappies.

When, a fortnight in the past, the IDF lastly despatched floor troops into Gaza, reducing the territory in half, they knew that to win this battle, they need to destroy the tunnels and the terrorists inside them.

The Israeli navy is reluctant to speak about this throughout an ongoing operation, however by long-standing contacts within the nation I spoke to a number of sources who defined the scenario they face.

‘The Hamas terror machine is a community of tunnels underneath Gaza, primarily in city areas,’ one senior Israeli official advised me. ‘It’s completely formidable. You can’t destroy Hamas’s navy machine with out coping with its subterranean terror community. That’s the reason we despatched our floor forces in.’

IDF sources inform me the tunnels vary from slender corridors of 6ft by 3ft to huge passageways that may take vehicles and even vehicles.

They’re swaddled in concrete and well-lit; they include command centres, ammunition depots and arms factories. They’re used to launch assaults on Israel and likewise to smuggle in every thing from automobiles to long-range weaponry.

Most are excessive sufficient to permit a person of common peak to face in and infrequently deep sufficient to keep away from the IDF’s bunker-busting bombs, which might penetrate as much as 130ft or 40m. Hiding underground means two issues. First, you might be more durable to seek out and kill; second, every thing above you — in Gaza that is hundreds of thousands of civilians — turns into your ‘cowl’. As Amichai Chikli, Israel’s Minister of Diaspora Affairs and Minister for Social Equality, advised me: ‘The most important menace is to the Gazan inhabitants as a result of all of those tunnel methods are coated by civilians. They’re actually human shields.’

One former defence official, who could not be named resulting from his lively reserve responsibility service, was even blunter, saying: ‘They’ve turned big swathes of the Strip into legit navy targets. These sons of b****** have deliberately put their tunnels underneath homes, mosques and hospitals to maximise civilian casualties. It is not simply cynical, it is pure evil.’

An essential query stays: how is Hamas in a position to spend hundreds of thousands of kilos buying the concrete, electrical energy and litres of gas and oxygen wanted to construct all this when Gaza is supposedly underneath complete lockdown by Israel?

The reply is so simple as it’s miserable. ‘For years the worldwide neighborhood has been sending cement into Gaza for housing, and Hamas has stolen it,’ says the senior Israeli official. ‘Nobody can cease them as a result of they’re the one individuals in Gaza with weapons.’

He continues: ‘They want the gas for his or her rockets but in addition to maintain the oxygen and lights on within the tunnels. For this reason they steal gas from Gazan civilians and humanitarian support deliveries — whether or not it’s desalination supplies for water or, most terribly, gas to energy mills for hospitals.’

Dr Daphné Richemond-Barak, professor at Israel’s Reichman College and creator of Underground Warfare, was clear: ‘I’ve little question any gas that will get into Gaza goes to Hamas. It might be an enormous mistake to ship gas into the Gaza Strip — it can simply lengthen the struggle,’ she advised me.

However constructing tunnels additionally requires tools and experience, and it’s right here that the image will get much more terrifying.

Terror group Isis, which rampaged by Iraq and Syria earlier than being smashed by coalition forces, has develop into an enormous affect on Hamas’s navy technique. Isis made in depth use of tunnels when it held the cities of Mosul in Iraq and Raqqa in Syria. Hamas has clearly imbibed the teachings realized there, too.

Based on Richemond-Barak the affect of Isis is crucial. ‘However now we have to keep in mind that Isis was combating within the tunnels in Syria and Iraq for just a few months at most,’ she says. ‘Hamas has been within the tunnels for over 20 years.’

However it isn’t simply Isis that has helped Hamas, however an entity way more highly effective and harmful: Iran.

‘Over 90 per cent of Hamas’s navy finances comes from Iran,’ the senior official tells me. ‘Iran has equipped weapons and helped Hamas with their indigenous weapons-building capabilities.

‘We all know there’s a shut working relationship between Iran’s Islamic Revolutionary Guard Corps and Hamas. They meet, they co-ordinate, they work collectively.’

When Hamas launched drones towards Israel throughout their final main conflict in 2021, it used Shehab drones primarily based on Iran’s Ababil-2 drone. In Ukraine, in current months, I’ve skilled assaults from Russian forces utilizing Iranian Shahed drones. An alliance of rogue actors is rising internationally. And in Gaza its presence is most clearly felt within the tunnels.

‘Always remember, the tunnels are the oxygen of a terrorist group that has refined navy infrastructure — and all of it’s inside these tunnels,’ says Richemond-Barak. ‘Every little thing you’d count on a navy to must wage battle, plan and execute assaults, manufacture and re-supply weapons is underground.

‘That is essential. The equipment of the enemy that seeks to destroy you is underground: that is the issue the IDF faces on the strategic degree.’

At a tactical and operational degree, the tunnels dictate how Israel’s navy operations will proceed, and the way the battle will play out.

Warfare of this kind poses a severe danger to the IDF. When combating underground, the navy should rethink the forces it deploys; the way it equips and trains troopers; and what tactical pointers it can put in place.

As Richemond-Barak argues: ‘Tunnel fight is usually one-on-one. In case you are wounded, you most likely will not be extracted and, after all, Hamas may be very eager on kidnapping Israeli troopers.

‘Then there are the booby traps. These might be something from improvised explosive gadgets (IEDs) to even hostages wired to blow.’

Tunnels change every thing on the tactical, strategic and operational degree. For this reason they’re such a menace for invading forces.

The Individuals used B-52 bombers to attempt to take out the Viet Cong tunnels in Vietnam, whereas final 12 months the Russians relentlessly bombed the Azovstal steelworks in Mariupol.

Armies historically deploy their strongest forces and weapons to cope with the tunnels. This, says Richemond-Barak, ‘explains the Israeli response’.

That response has to this point mixed bombing from the air — which incorporates the dropping of sponge bombs of liquid foam that expands and hardens to seal up tunnels — and the usage of canine and robots on the bottom.

Proper now, elite Israeli Yahalom ‘diamond’ items are looking for tunnels to destroy.

Their colleagues in Samur (‘Weasel’) unit — commandos skilled in subterranean warfare — might be despatched in to struggle Hamas terrorists hand-to-hand.

What Israel is going through is a extremely refined, well-armed and well-funded terror group working from what’s, to all intents and functions, an underground metropolis of terror that has no equal anyplace else on this planet.

It’s one backed by Iran, a overseas energy with a extremely refined political and navy equipment.

Make no mistake, the objective of each Iran and Hamas is not only to destroy Israel however the Western alliance that helps it.

If the Israel-Hamas battle appears distant, it isn’t. That is no totally different from the battle towards al-Qaeda or Isis. It’s the identical model of harmful, radical Islamism now we have skilled in elements of the UK, U.S. and Europe. Consider me, the battle is just not as distant as it could at first appear.

On the finish of our dialog, Israeli minister Amichai Chikli made a plea: ‘We actually want the assist of the civilised world, to destroy Hamas. Individuals want to know that the identical ideology might be discovered within the U.S. and Europe — and it should be fought simply as strongly there, too.’
