Hezbollah leader Hassan Nasrallah was killed in an Israeli airstrike last year while meeting with senior officials, according to a senior Hezbollah official. The strike, which hit Beirut's southern suburbs, escalated months of low-level strikes into a full-scale war between Israel and Lebanon, lasting two months until a U.S.-brokered ceasefire in November 2023. Hezbollah is expected to relocate north while Israeli forces withdraw. Naim Kassem, Nasrallah’s successor, has threatened retaliation if Israel doesn't comply with withdrawal terms. Ongoing tensions persist as international negotiations continue.
