Why was Hezbollah using pagers?

Annika Burgess has covered off everything we know about the pager explosions in this story:

Hezbollah vows to retaliate against Israel

In a statement on Wednesday (local time), Hezbollah said:

"The resistance will continue today, like any other day, its operations to support Gaza, its people and its resistance which is a separate path from the harsh punishment that the criminal enemy (Israel) should await in response to Tuesday's massacre."

Gold Apollo founder says pagers were made by company called BAC

Gold Apollo founder Hsu Ching-Kuang has revealed BAC as the company which produced the pagers using their brand name and logo.

The company said in a statement that the AR-924 model was produced and sold by BAC.

"We only provide brand trademark authorization and have no involvement in the design or manufacturing of this product," the statement said.

Ching-Kuang said Gold Apollo and BAC established a relationship three years ago.

EU's top diplomat warns 'tomorrow is too late' for Israel-Gaza ceasefire

European Union foreign policy chief Josep Borrell has warned every day that passes without a ceasefire in the Israel-Gaza war risks the lives of hostages as well as a regional war breaking out.

"The only thing I can say is that all actors involved have to continue pressure on both parties to reach this agreement," Borrell said.

Borrell came before journalists just after news broke from Lebanon of at least nine people killed and about 2,800 injured from exploding pagers. 

He said he would seek more information from Beirut, but acknowledged it could escalate the already-boiling tensions in the region.

"Certainly there is the possibility of the war spilling over to Lebanon."

Pagers on display at Gold Apollo's office in New Taipei City

Gold Apollo have said the pagers used in the explosion were made by a company in Europe that had the right to use the Taipei-based firm's brand.

Lebanon blasts will leave Hezbollah 'insecure', national security expert says

Jennifer Parker, a senior adviser at the ANU's National Security College, says it's not a large leap to think Israel may be responsible for the explosions given its history of attacking its enemies remotely.

"Israel hasn’t claimed responsibility, but traditionally Israel don’t claim responsibility for assassination attempts, so that’s not a surprise," she told ABC News Channel.

“And we do know that there’s a history of Israel using things like mobile phones to undertake assassinations."

Ms Parker said it's clear Israel does understand decisions that are being made within the command of control of Hezbollah, in terms of the equipment they are acquiring.

Breaking: Gold Apollo says it did not make the pagers, Reuters reports

Gold Apollo's company founder Hsu Ching-Kuang has told reporters they did not make the pagers that were used in the detonations in Lebanon on Tuesday (local time).

Ching-Kuang said the pagers were made by a company in Europe that had the right to use the Taiwanese firm's brand. 

"The product was not ours. It was only that it had our brand on it," he said.

He did not name the company which he said manufactured the pages.

A senior Lebanese security source told Reuters earlier that Hezbollah had ordered the pages from Taiwan-based Gold Apollo.

Still no comment from Israel

It is now 5am in Israel and Lebanon. 

People will slowly start waking up and the thousands of pager detonations targeting Hezbollah members across Lebanon are likely to be at the top of both country's agendas. 

Both Hezbollah and the Lebanese government have blamed the Israel Defense Forces (IDF) for the blasts. 

The Israeli government has not provided a comment so far, but this is expected to come later today.

Israeli media reported the IDF was "on alert" after Hezbollah's threat to retaliate, with Defense Minister Yoav Gallant holding a meeting with the military's chief of staff, General Herzi Halevi, on Tuesday evening, local time.

Further comment may also come from Iran and the US — the two sides' main allies.

Hezbollah members were told to destroy their phones in February

In a televised speech on February 13, Hezbollah's Secretary-General Hassan Nasrallah sternly warned supporters that their phones were more dangerous than Israeli spies.

He told them to "break, bury or lock them [phones] in an iron box".

So to still allow for communication, the group opted to distribute pagers to Hezbollah members across the group's various branches — from fighters to medics.

However, small explosives placed in the Taiwan-made pagers at a "production level" went "undetected" by Hezbollah for months, according to a senior Lebanese security source who spoke to Reuters.
