Hezbollah was still distributing pagers to its members hours before the recent explosions, indicating confidence in their safety despite ongoing security checks. The Gold Apollo branded pagers detonated across Hezbollah strongholds, killing 37 people and injuring over 3,000. The batteries of the walkie-talkies used by Hezbollah were laced with the highly explosive compound PETN. Hezbollah suspects Israel detonated the walkie-talkies to prevent their discovery. The group is conducting an investigation into the devices and believes Israel feared the walkie-talkies were also rigged with explosives.
