Bulgarian and Norwegian authorities are opening investigation related to Pagers explosions incident in Lebanon

Bulgaria and Norway on Thursday became new focal points in a global hunt to determine who supplied Hezbollah with thousands of pagers that exploded in Lebanon this week in a major blow to the Lebanese group.

Security sources said Israel was responsible for Tuesday’s blasts, which killed 12 people, wounded more than 2,300 and intensified an escalating conflict between the two sides.

It’s not clear how the Pagers explosions was carried out or with the help of whom, although there are possible leads so far in Taiwan, Hungary and Bulgaria.

With still no clear information regarding how and when explosives were planted in the devices so that they could be detonated remotely.

The same question remains about the hundreds of mobile communication devices used by Hezbollah that exploded on Wednesday in a second wave of attacks.

One theory suggests that the pagers were intercepted and rigged with explosives after leaving the factories.

Another theory is that Israel planned the entire deadly supply chain.

Bulgarian authorities said on Thursday that the interior ministry and security services had opened an investigation into the possible connection of a company to the matter.

Local media reports said that Sofia-based Norta Global Ltd facilitated the sale of pagers to Hezbollah.

Bulgaria’s BTV channel, citing security sources, reported that 1.6 million Euros linked to the purchase passed through Bulgaria before being transferred to Hungary.

Emails couldn’t be sent to Norta’s email address listed in the Bulgarian company’s records, and the company’s founder declined to comment.

Images of the exploded pagers analyzed by Reuters showed a shape consistent with devices made by Taiwanese company Gold Apollo. Gold Apollo said on Tuesday the pagers were made by Budapest-based BAC Consulting.

Cristiana Bársony Arcidiacono, the company’s owner and CEO, didn’t respond to multiple requests for comment sent by phone and text message.

However, she told NBC News, Wednesday that her company works with Gold Apollo, but has nothing to do with the pagers.

“I’m just the middleman,” she said, “I think you’ve got it all wrong”.

The Hungarian news website Telex reported, citing sources, that Norta Global Ltd coordinated the sale.

Norta has a registered office in Bulgaria, in an apartment building in the capital Sofia, which houses nearly 200 other companies, according to a local company registry office. There was no sign of the company’s existence.

Lawyer Vladimir Kuzmanov, who said he represented the company, was at the headquarters but declined to answer questions when contacted by Reuters on Thursday.

Norta Global’s website content was removed on Thursday.

The website previously had versions in English, Bulgarian and Norwegian, and advertised services including consulting, technology, recruitment and outsourcing.

“Looking for a flexible company to help you succeed or find the right technology solution for you? Look no further,” the website said, according to a copy of it seen by Reuters before the change.

Norta founder Renson Jose is based in Norway.

He declined to comment on the pager incident when reached by phone and hung up when asked about the company’s activities in Bulgaria.

His neighbors in a quiet suburb of Oslo said they knew little about him.

Amon Goff, chief executive of DN Media, where Jose now works, told Reuters he was aware of the reports and had informed police and security services.

He said, Jose was traveling to the United States.

“We take these matters seriously,” Goff added.

Oslo police said they had begun preliminary investigations into the new information.

Norway’s domestic intelligence service said it was aware of the situation and declined to comment further.

There is no evidence of a link between DN Media and Norta.

Barshon Arcidiaconu of BAC Consulting vacated her Budapest apartment on Wednesday, a neighbor told Reuters.

A Reuters reporter who was there said the door was partially open on Wednesday but was closed on Thursday morning, with no one answered the doorbell.

A Lebanese security source told Reuters that Hezbollah believed it had ordered pagers from Gold Apollo and that they were produced in Asia, not Europe.

The source added that Hezbollah saw that it would be much easier for the Israeli intelligence agency (Mossad) to operate in Hungary.

“It’s likely that Mossad established a European company,” the source said.

It’s worth noting that the leader of the Lebanese Hezbollah, Hassan Nasrallah, said in a speech on Thursday that the party had formed investigation committees to determine the circumstances of the operation, and that it now practically knows how everything happened.
