Bulgaria's state security agency, DANS, has announced an investigation into a company linked to the sale of pagers to Hezbollah, which were used in a coordinated terrorist Israeli attack in the past two days.

DANS is working with the Interior Ministry to examine the involvement of the unnamed company registered in Bulgaria.

According to the agency's statement, no shipments of the suspect pagers have been detected on Bulgarian territory.

Earlier, Japanese company Icom pointed out that it discontinued production of the radio model reportedly involved in the recent explosions in Lebanon around a decade ago.

"The IC-V82 is a handheld radio that was produced and exported, including to the Middle East, from 2004 to October 2014. It was discontinued about 10 years ago, and since then, it has not been shipped from our company," Icom stated.

The firm also clarified that the production of batteries required for the device had been discontinued and that the absence of a holographic seal, which is used to authenticate genuine products, made it impossible to confirm whether the device had been shipped by Icom.

Additionally, Icom emphasized that products destined for overseas markets are sold exclusively through authorized distributors, claiming that its export program adheres to Japanese security trade control regulations.

"All of our radios are manufactured at our production subsidiary, Wakayama Icom Inc., in Wakayama Prefecture, under a strict management system... so no parts other than those specified by our company are used in a product. In addition, all of our radios are manufactured at the same factory, and we do not manufacture them overseas," the statement read.

'Israel' planted explosives in pagers sold to Hezbollah: NYT

"Israel" planted explosive material in a recent batch of Taiwanese-brand pagers imported to Lebanon, carrying out an operation against Hezbollah on Tuesday, The New York Times reported, citing US and other officials briefed on the attack.

Pagers ordered by Hezbollah from Gold Apollo were tampered with before arriving in the county, some officials stated. Most pagers were the AR924 models, but the shipment also included three other models from the company, according to NYT.

Taiwanese manufacturer Gold Apollo said the pagers were produced and developed by a European company, CEO Hsu Chin-Kuang said on Wednesday.

"The pagers were both developed and produced abroad, so they have nothing to do with Taiwan," the Director was quoted as saying by Taiwanese news portal CTWANT.

He also said that about three years ago, Gold Apollo signed a cooperation agreement with a European company, which was only involved in distributing Gold Apollo products at first, but later began independently developing the pagers involved in the blasts.

The explosive material, weighing less than 60 grams, was implanted next to the battery in each device, two officials said. An embedded switch was also planted in the pagers, allowing for remote detonation of the explosives.

Three officials said that the devices were programmed to beep for several before exploding.

It is unclear when the devices were ordered or arrived in Lebanon. However, several officials said over 3,000 pagers were ordered from the Taiwanese company and distributed to Resistance members throughout the country.

Independent cybersecurity experts confirmed that the strength and speed of the explosions were caused by a form of explosive material, based on footage of the attack.

“These pagers were likely modified in some way to cause these types of explosions — the size and strength of the explosion indicate it was not just the battery,” said Mikko Hypponen, a research specialist at software company WithSecure and Europol cybercrime advisor. 

'Israel' clearly intended to target Lebanese civilians: The Guardian 

"Israel", in its recent terrorist attacks using booby-trapped pagers and two-way radios, which were detonated indiscriminately among Lebanese citizens, has violated decades-long war treaties that were created for attacks of this sort, The Guardian pointed out on Wednesday, adding that the world is at the edge of war, "and none of this would be possible" without the United States "complicity and assistance."

In an editorial titled "The Guardian view on Israel’s booby-trap war: illegal and unacceptable," the newspaper mentioned that the treaty prohibits "in all circumstances to use booby-traps or other devices in the form of apparently harmless portable objects that are specifically designed and constructed to contain explosive material."

Over 3,200 people were wounded, and more than 30 were martyred – including women and children–in two separate Israeli terrorist attacks on Tuesday and Wednesday, involving the remote detonation of booby-trapped pagers and two-way radios. The devices exploded while their holders were going about their daily lives—shopping, sitting with family, working, or driving on busy roads—placing everyone nearby in immediate danger.

On that, the British newspaper criticized describing the attacks as “surgical” or a “precisely targeted anti-terrorist operation” by advocates and supporters of the Israeli occupation.

"The pager bombs were clearly intended to target individual civilians – diplomats and politicians – who were not directly participating in hostilities," The Guardian said, explaining that in legal terms, this would be called by lawyers as "excessive incidental civilian harm."

The newspaper also shed light on the Western double standards when addressing Israeli actions. It mentioned how Russia has been accused of committing alleged war crimes in Ukraine over the same actions "Israel" is committing. But, the author mockingly added, "It’s hard to say why the same reasoning is not applied to Israel – apart from that it is a Western ally."

The piece also warned against normalizing the "unprecedented" Israeli attacks, because "if that is the case, the door is opened for other states to lethally test the laws of war."

It added that US President Joe Biden shows "no sign of intervening to stop the bloodshed," referring to the ongoing genocide in Gaza and the terrorist attacks in Lebanon, calling on Washington to "restrain its friend."

There is concern that Israeli attacks could lead to a full-scale war, drawing the US into it in the region.

The piece, also mockingly, said "perhaps" after the presidential elections, the US would be able to tell Israeli Prime Minister Benjamin Netanyahu that "saving [his] skin should not be paid in the streets of Lebanon or by Palestinians in the occupied territories."

It also suggested that the US may only reconsider its stance after its presidential election, recognizing that protecting Prime Minister Netanyahu should not come at the expense of Lebanese civilians or Palestinians in the occupied territories.

"Until then, the rules-based international order will continue to be undermined by the very countries that created the system," The Guardian's editorial concluded.
