Pagers and walkie-talkies, considered outdated modes of communication, were weaponised for a one-of-its-kind attack in Lebanon, resulting in a series of explosions for two consecutive days, killing 32 and injuring over 3,000 across the country.

The attack targeted Hezbollah operatives by planting explosive devices inside hand-held pagers and walkie-talkies. 

One Western security source says that a military unit that is not part of the spy agency involved in the development stage of the operation.

Lebanon has blamed Israel for the sabotage of thousands of pagers that caused them to explode, killing several people and wounding thousands, in an apparent bid to weaken the Islamist militant group Hezbollah.

Thousands of pagers used by members of the militant group Hezbollah simultaneously exploded in parts of Lebanon and Syria on Tuesday afternoon, killing at least nine people and injuring more than 2,700.

The mass pager attack against Hezbollah in Lebanon has turned the spotlight on Israel's secretive Unit 8200, the Israel Defense Forces' intelligence unit, which a Western security source said was involved in planning the operation.

The coordinated attack, which led to the simultaneous detonation of hundreds of pagers used by Hezbollah members in Lebanon, has drawn attention due to the advanced technology and meticulous intelligence behind it.
