Israel simultaneously detonated thousands of pagers used by Lebanese Hezbollah members across Lebanon and Syria on September 17. Lebanese officials reported that around 2,800 individuals were injured, though some reports suggest that the number is closer to 4,000, most of whom are Hezbollah members. Israel reportedly executed the attack by planting one-to-two ounces of explosive material and remote triggers inside a batch of Taiwanese-made pagers en route to Lebanon. Hezbollah had ordered the pagers to communicate across its ranks, as Hezbollah Secretary General ordered group members to limit cellphone usage in order to avoid Israeli detection. Hezbollah responded to the attack by blaming Israel and vowing to retaliate.
