Hezbollah leader Hassan Nasrallah was killed in an Israeli airstrike, marking a significant escalation in the ongoing conflict between Israel and Hezbollah. Nasrallah, who led Hezbollah for over 30 years, was a key figure in the group's military and political strategies against Israel. His death has led to increased violence in Lebanon, with heavy Israeli airstrikes resulting in numerous casualties. Iran's Supreme Leader has called for support for Hezbollah in response to Nasrallah's killing.
