Shock moment shopper with ‘Hezbollah pager’ is blasted by Israeli bomb hidden in gadget sending shop assistant fleeing

THIS is the shocking moment a suspected Hezbollah pager packed with an Israeli bomb detonates inside a shop in Lebanon - sending workers fleeing.

At least 37 people have been killed and over 3,000 injured in remote-controlled device explosions across Lebanon this week - as Mossad spies seek to take down terror group Hezbollah.

Shocking video shows one of the Iran-backed group's pagers exploding on CCTV filmed inside a convenience store.

Two shop assistants work at their tills serving customers, with one man on the left reaching down to check what looks like a pager in his pocket.

As he pulls it from his trousers an explosion rings out, sparking a huge cloud of smoke.

Both shop assistants clamp their hands over their ears and desperately scramble to flee the shop.

Lebanese security forces claim Israeli Mossad spooks planted explosives inside thousands of the old-school devices used by Hezbollah, months before the blitz.

Top brass inside the militant group ordered its fighters to swap phones for pagers in a failed move to keep Israel from tracking them.

Mossad reportedly intercepted the devices on the supply route and packed them with the explosive PETN.

Some reports claim the notorious spy agency even set up shell companies to build the devices from scratch themselves.

After the initial wave of pager blasts on Tuesday, other devices including walkie-talkies, fingerprint scanners, home solar systems and radios also exploded in Lebanon on Wednesday.

Hezbollah leader Hassan Nasrallah hit out against Israel in a speech, saying the "enemy" had crossed "all limits, rules and red lines" in a "massacre".

He dubbed it a "declaration of war".

Meanwhile Israel moved hordes of troops to its northern border with Lebanon and unleashed a wave of airstrikes on the country.

The Israel Defence Forces (IDF) hit seven targets in the country after Defence Minister Yoav Gallant said a "new phase" of war had begun.

Warplanes fired on settlements in southern Lebanon overnight and heavy artillery also fired across the northern border.

Two Israeli soldiers were killed near the border, the IDF said.

The country's N12 news said one was killed by a drone and the other by an anti-tank missile fired by Hezbollah from Lebanon.

Israeli sources said the toll from the two-day blitz on Hezbollah communications is higher than the terror group has admitted.

Reports say Hezbollah’s elite group of fighters - known as The Radwan Unit - has been hit particularly hard by the pager strike.

Doctors in Lebanese hospitals have been overwhelmed by a flood of admissions following the double-tap hack and said many casualties were left blinded.

Others had fingers or entire hands blown off while those who had pagers and walkie talkies in their pockets suffered appalling leg and groin injuries.

Dr Elias Warrak, who works at an eye hospital in Lebanon, described Wednesday as “the worst day of [his] life as a physician”.

He revealed at least 60 per cent of the people he had seen had lost at least one eye and some had suffered brain damage.
