A major security breach occurred as thousands of Hezbollah's pager devices exploded across Lebanon, resulting in numerous casualties. Initial reports in the morning indicated over 3,000 injuries. By afternoon, the death toll reached 12 with nearly 2,800 wounded. Israel was accused of orchestrating this sophisticated attack, which targeted Hezbollah's communication network. The incident was described as the most significant security breach between Hezbollah and Israel, potentially altering the "rules of engagement". A second wave of explosions targeting wireless communication devices occurred later in the day, causing additional casualties. Hezbollah vowed retaliation, while international reactions poured in. The Lebanese government initiated diplomatic contacts, and questions arose about the potential for a wider conflict.
