Deadly Israeli attacks that blew up Hezbollah radios and pagers crossed all red lines, the leader of the heavily armed Lebanese movement said on Thursday (September 19, 2024), in a speech broadcast as sonic booms from Israeli warplanes shook buildings in Beirut.

Lebanon and Hezbollah have blamed Israel for attacks on Hezbollah’s communications equipment that killed 37 people and wounded around 3,000, overwhelming Lebanese hospitals and wreaking bloody havoc on Hezbollah. Israel has not directly commented on the attacks, which security sources say were probably carried out by its Mossad spy agency.

“There is no doubt that we have been subjected to a major security and military blow that is unprecedented in the history of the resistance and unprecedented in the history of Lebanon,” Hezbollah leader Hassan Nasrallah said in his TV address, filmed at an undisclosed location.

“This type of killing, targeting and crime may be unprecedented in the world,” he said, appearing in front of a featureless red background in his customary black turban.

The attacks “crossed all red lines”, he said. “The enemy went beyond all controls, laws and morals,” he said adding the attacks “could be considered war crimes or a declaration or war, they could be called anything and they deserve to be called anything. Of course that was the intention of the enemy.”

As the broadcast was aired, deafening sonic booms from Israeli warplanes shook Beirut, a sound that has become common in recent months but has taken on a greater significance as the threat of all-out war has steadily ramped up. Israel said its warplanes struck southern Lebanon overnight. Hezbollah reported that airstrikes resumed in the border area in the afternoon.

The attacks on Hezbollah communications equipment sowed fear across Lebanon, with people abandoning electronic devices for fear of carrying bombs in their pockets.

“Who can even secure their phone now? When I heard about what happened yesterday, I left my phone on my motorcycle and walked away,” said Mustafa Sibal on a street in Beirut.

The Lebanese army said on Thursday (September 19, 2024) it was blowing up pagers and suspicious telecom devices in controlled blasts in different areas. It called on citizens to report any suspicious devices.

Lebanese authorities banned walkie-talkies and pagers from being taken on flights from Beirut airport until further notice, the National News Agency reported. Such devices were also banned from being shipped by air.

Hezbollah fired missiles at Israel on the day after the October 7 cross-border attack by the Palestinian militant group Hamas which triggered the Gaza war, and since then constant exchanges of fire have occurred. Although neither side has allowed this to escalate into a full-scale war, it has led to the evacuation of tens of thousands of people from the border area on both sides.

“The Hezbollah terrorist organization has turned southern Lebanon into a combat zone. For decades, Hezbollah has weaponized civilian homes, dug tunnels beneath them, and used civilians as human shields,” Israel’s military said.

“The IDF (Israel Defence Forces) is operating to bring security to northern Israel in order to enable the return of residents to their homes, as well as to achieve all of the war goals.”

Israel said its warplanes struck villages in southern Lebanon overnight, and a security source and Hezbollah’s al-Manar TV reported airstrikes near the border began again on Thursday just after midday.

Hand-held radios used by Hezbollah detonated on Wednesday across Lebanon’s south, killing 25 people and wounding hundreds.

The previous day, hundreds of pagers — used by Hezbollah to evade mobile phone surveillance — exploded at once, killing 12 people including at least two children, and injuring more than 2,300.

Lebanese Prime Minister Najib Mikati called on the United Nations Security Council to take a firm stand to stop what he called Israel’s “aggression” and “technological war” against his country.

Israel says its conflict with Hezbollah, like its war in Gaza against Hamas, is part of a wider regional confrontation with Iran, which sponsors both groups as well as armed movements in Syria, Yemen and Iraq.

Assassination plot

Also on Thursday (September 19, 2024), Israeli security forces said that an Israeli businessman had been arrested last month after attending at least two meetings in Iran where he discussed assassinating Prime Minister Benjamin Netanyahu, the Defence Minister or the head of the Shin Bet spy agency.

Last week, Shin Bet uncovered what it said was a plot by Hezbollah to assassinate former Defence Minister Moshe Ya’alon.

Israel has been accused of assassinations including a blast in Tehran that killed the leader of Hamas and another in a Beirut suburb that killed a senior Hezbollah commander within hours of each other in July.

Despite the events of the past few days, a spokesperson for the U.N. peacekeeping mission in southern Lebanon said the situation along the frontier had “not changed much in terms of exchanges of fire between the parties”.

“There was an intensification last week. This week it is more or less the same. There are still exchanges of fire. It is still worrying, still concerning, and the rhetoric is high,” the spokesperson, Andrea Tenenti, said.

On Sunday (September 15, 2024), Benjamin Netanyahu, the Israeli Prime Minister, told his security Cabinet that he would do whatever necessary to make sure that the 70,000 Israelis displaced from the northern border villages by the fighting with Hezbollah, return home. Two days later, on Tuesday (September 17, 2024), in the late afternoon, hundreds of pagers, a low-tech messaging device, started exploding simultaneously across Lebanon and parts of Syria. At least 12 people were killed and over 2,800 were injured. A day later, on Wednesday (September 18, 2024), walkie-talkies and other electronic devices exploded in Lebanon, leaving 20 more dead and at least 450 others injured.

The explosions mostly hit Hezbollah, the Shia militia group backed by Iran which has been using pagers and walkie-talkies for communication among its ranks. Hezbollah immediately blamed Israel for the attack. Iran accused Israel of mass murder in Lebanon. Several others raised questions about weaponising civilian communication devices. Lebanon’s health officials said there were at least two children among the dead and that they can’t say with certainty how many of the victims were civilians and how many of them were Hezbollah members. Israel has neither confirmed nor denied its role in the explosions — its standard response when it comes to controversial overseas operations. But if Israel is really behind the attack, the question is how they pulled an attack of this scale off.

Taiwanese connection

Initially there were different theories pointing to different possibilities, including cyber warfare and supply-side penetration to tamper with the devices. Most of the pagers that exploded were AR924s that carried the brand name of Gold Apollo, a Taiwan-based company founded in 1995. After Tuesday’s (September 17, 2024) explosions, Gold Apollo issued a statement, saying it was not involved in the production of the pagers in question. “The product was not ours. It was only that it had our brand on it,” Gold Apollo founder and president, Hsu Ching-kuang, told reporters at the company’s office in New Taipei on Wednesday (September 18, 2024).

In the statement, the company said the AR924 model pagers were manufactured by BAC Consulting KFT, a Hungarian company. “Gold Apollo has established a long-term partnership with BAC Consulting”, and it has authorised “BAC to use our brand trademark for product sales in specific regions, but the design and manufacturing of the products are entirely handled by BAC,” the short statement said. Gold Apollo did not offer any details about its contract with BAC.

Hungarian connection

BAC Consulting, based in Budapest, operates in “environmental, political and development projects”, according to the company’s LinkedIn page, which has 303 followers as of Thursday (September 19, 2024). The page has no reference to the company’s involvement in manufacturing of electronic devices. It says BAC works to find “innovative solutions” to tackle challenges of “development, international affairs and environment”. Cristiana Rosaria Bársony-Arcidiacono, a 49-year-old PhD in particle physics, is the CEO of the company.

According to Ms. Bársony-Arcidiacono’s LinkedIn profile, she has advocated “environmental and social causes for developing and fragile countries” and has published articles in science journals. She did her PG masters in SOAS, London, and a diploma in politics from the London School of Economics and Political Science. But what does a particle physics PhD with experience in the fields of environmental and developmental consulting have to do with pager manufacturing? “I don’t make the pagers. I am just the intermediate. I think you got it wrong,” Ms. Bársony-Arcidiacono told U.S. broadcaster NBC on the phone. But she did not say BAC was not involved. And if Gold Apollo is to be believed, the little-known Budapest-based company that claims to be working in the fields of development and environment consulting was designing and manufacturing Taiwanese pagers and selling them to Hezbollah in Lebanon and parts of Syria. And they exploded at a critical juncture of the Hezbollah-Israel war. Both the knowns and unknowns of the explosion saga point to bigger behind-the-scenes players.

The hidden hand

According to a New York Times report, which cites defence and intelligence officials, BAC Consulting was a front company of the Israeli intelligence agencies. The report says Israeli intelligence officials set up three shell companies, including BAC, which was formally registered in Hungary in 2022. Hezbollah was wary of using cell phones, fearing Israeli penetration. They turned to pagers for communication, and Israel established a company to make those pagers — with inbuilt PETN (pentaerythritol tetranitrate) explosives, and a switch to detonate them remotely.

The back-to-back explosions have dealt a blow to Hezbollah, whose senior commander Fuad Shukr was assassinated by Israel on July 30 in Beirut. Israel has once again demonstrated its willingness and capability to take great risks in attacking its rivals. But with Hezbollah vowing vengeance, tensions on Israel’s northern border are likely to flare up in coming days.

Scenes of people bleeding and being rushed into hospitals flashed on television screens and social media platforms on Tuesday (September 17, 2024) evening in Lebanon. The attack, targeted at armed group Hezbollah, killed at least nine and injured several thousands, including Iran’s envoy to Beirut. The Lebanese Information Minister Ziad Makary condemned the attack as an “Israeli aggression”.

CCTV footage of blasts in multiple parts of the Middle Eastern country surprised the Iran-backed Hezbollah as two of its fighters and an 8-year-old girl were killed. The militant group vowed to retaliate against Israel for the blasts. The simultaneous explosions occurred largely in the southern part of Lebanon—a Hezbollah stronghold. Israel’s military has declined to comment.

But the biggest surprise of this attack lies in the weapon used by the perpetrator. The devices behind the serial blasts were unsophisticated, low-tech gadgets: pagers.

What are pagers and how do they work?

Pagers, often called beepers, are communication devices that emerged in the mid-20th century. Their presence was eclipsed by the cellular phones that grew in popularity in the 1990s and 2000s. And subsequently, the dawn of the smartphone pushed the pagers into the shadows. But the humble, palm-sized device had its own strengths that played out well in specific circumstances.

Pagers operate using radio signals, which are transmitted by towers and received by the device. They function as either one-way or two-way systems. One-way pagers receive messages from a central transmitter but cannot send replies. That means a user can receive numeric or alphanumeric messages, and the device alerts them through a beep or vibration.

In a two-way system, the pagers are capable of handling communication in both directions. Users can receive and respond to messages, which makes them slightly more advanced, but these are still limited in functionality compared to modern smartphones.

Pagers rely on a network of radio towers that broadcast signals over a wide area. In many cases, they are more reliable than mobile phones in certain conditions because their communication system operates over simple, robust radio waves, often penetrating areas where cell coverage might be weak.

Despite their technological obsolescence in mainstream use, pagers are still valued in healthcare, emergency services, and remote locations where cellular networks are unreliable. Their simplicity ensures they are more energy-efficient and less prone to network outages.

How are pagers useful in covert operations?

Pagers are relatively unsophisticated compared to smartphones or other modern gadgets, which make them less susceptible to high-tech surveillance techniques. They don’t have GPS or internet connectivity, reducing the risk of location tracking and hacking. Intelligence agencies rely heavily on digital footprints, but pagers are harder to monitor remotely.

Secondly, pagers use radio frequencies, which makes it harder for interception compared to cellular or internet-based communication devices. This feature makes them ideal for sending short, encrypted, or coded messages in sensitive situations. And with one-way pagers, the risk of being detected is lower since the device does not transmit a response, making it difficult for intelligence agencies or adversaries to trace the origin or location of the message.

Thirdly, their simplicity plays a key role in how they can be manipulated, which could be a highly likely reason as to why it was used in the Hezbollah attack. Pagers can be modified to include circuits that trigger a signal when a specific message is received. These modifications are used in covert operations to activate explosives or send alerts without raising immediate suspicion.

Where else were low-tech, remote detonators used prior to the Hezbollah attack?

While it is unclear whether pagers were used to trigger blasts prior to the Hezbollah attack, there are several instances of remote detonators being used in conflict situations.

Armed groups use radio-controlled Improvised Explosive Devices (IEDs) to detonate explosives from a distance. Attackers use such systems to bomb high-profile targets, including police stations and government building.

These remote systems can even be deployed in a car or at the level of a doorbell to trigger explosions. And such devices are difficult to trace because they emit weak signals that could be mistaken for background noise or ignored by conventional detection methods. Simple everyday consumer electronics and communication gadgets can also be used to detonate IEDs remotely.

Why the pager attack will be a new tool in the armed conflict’s playbook?

Their small size and outdated appearance make pagers an ideal device to send short, encrypted texts that can’t be picked up by the intelligence community. But turning that unsophisticated device into a weapon to attack an adversary is nothing short of a page from a spy novel.

While Israel has declined to comment on the blasts, it is overwhelmingly clear who could have pulled off such a massive operation.

A Reuters report revealed that the pagers in the explosion bore Gold Apollo’s branding. While the Taiwan-based company has denied making the pagers used in the blasts in Lebanon, the company’s founder, Hsu Ching-Kuang, clarified that the devices were manufactured by a European firm licensed to use their brand.

Gold Apollo insists it was not responsible for the product and expressed embarrassment over the incident. Hezbollah, a militant group, reportedly ordered thousands of pagers, which they believed could help evade Israeli tracking systems.

Experts are hypothesising myriad ways by which this attack could have been planned and executed. But there is nothing conclusive yet. It is unclear whether the devices were bugged at the manufacturing level or at the supply chain level.

Nevertheless, the pager attack comes amid growing tensions between Israel and Iran-backed Hezbollah. The duo have been exchanging fire across the Israel-Lebanon border since the start of the Gaza war in October. And this operation could very well start a new phase in the prolonged regional conflict.
