• Israel launched air strikes against Hezbollah after the group attacked an Israeli missile defense site.
• Hezbollah's attacks were in retaliation for the killing of Iran’s Supreme Leader, Ali Khamenei.
• Heavy bombardment in Beirut resulted in at least 31 fatalities and hundreds of injuries.

Following Hezbollah's launch of rockets and drone strikes aimed at an Israeli missile defense site south of Haifa, Israel responded with air strikes targeting Hezbollah positions across Lebanon. The Shi'ite militant group claimed its attack was a "legitimate defensive response" to what it described as ongoing Israeli aggression and the assassination of Iran's Supreme Leader, Ali Khamenei, emphasizing their right to defend themselves and retaliate accordingly. Hezbollah described its operation as retaliation, urging a halt to U.S.-Israeli actions against them, according to aljazeera and reuters.

In response, Israeli air force bombings targeted multiple areas, including southern Beirut, where numerous explosions occurred. The strikes aimed at Hezbollah strongholds and were noted to have resulted in at least 31 deaths and injuries to 149 others. The Israeli Defense Forces (IDF) stated that they had commenced an "offensive campaign" against Hezbollah, moving beyond defensive measures and taking a more aggressive stance. Such operations are expected to continue for several days as tensions remain high, citing the need for heightened readiness on their part, according to reuters, indiatimes, and indiatimes.

The escalation marks a significant deterioration in the recent U.S.-brokered ceasefire established in November 2024, which had seen relative calm between Israel and Lebanon. As Israel continues to launch air strikes throughout regions controlled by Hezbollah, the military has issued evacuations for residents in southern Lebanon, identifying them as being in imminent danger from further bombings. The chaotic scenes in Beirut, where residents were awakened by explosions and subsequently fled, underline the potential for increased civilian casualties in this renewed conflict, according to aa and indiatimes.

Hezbollah's retaliatory strikes are the first since the escalation of U.S.-Israeli operations against Iranian interests, marking a key step in the regional conflict dynamic following Khamenei's death. The conditions for a lasting peace appear increasingly precarious as both sides engage in tit-for-tat military actions, generating significant concerns regarding the stability of the region and the potential for broader conflict, according to reuters and indiatimes.
