Israel launched a massive airstrike on Beirut, targeting Hezbollah's headquarters. Initially, reports were unclear about the fate of Hassan Nasrallah, the group's leader. By mid-morning, Israel claimed to have killed Nasrallah, a claim later confirmed by Hezbollah. The assassination sparked immediate international reactions. Iran's Supreme Leader was reportedly moved to a secure location and vowed retaliation. US President Biden called the killing "a measure of justice," while Netanyahu hailed it as a "historic turning point." The event triggered fears of wider regional conflict, with over 50,000 people fleeing to Syria. As tensions escalated, Israel braced for potential revenge attacks. The day's events marked a significant escalation in the ongoing Middle East crisis, potentially altering the balance of power in the region.
