The US-Israeli war on Iran expanded dramatically on March 2 when Hezbollah launched missiles and drones at an Israeli military site in Haifa — the first such attack in over a year — and Israel responded with devastating strikes on Beirut’s southern suburbs, killing at least 52 people and wounding 154 in a single day.
The opening of the Lebanon front transformed the conflict from a US-Israeli campaign against Iran into a multi-front regional war, drawing in one of the Middle East’s most powerful non-state armed groups and threatening Lebanon with a repeat of the catastrophic displacement events of September 2024.
Hezbollah Strikes Haifa
Hezbollah announced that it had launched a coordinated missile and drone attack against Israeli military positions in Haifa, citing the assassination of Iran’s Supreme Leader Ayatollah Ali Khamenei as the direct justification.
The attack marked the first time Hezbollah had struck Israeli territory in over a year, following a November 2024 ceasefire that had temporarily halted cross-border hostilities. The group’s statement made clear that the ceasefire was no longer operative and that it considered the killing of Khamenei an attack requiring a response.
Hezbollah Secretary-General Naim Qassem described the conflict as an “existential” battle, framing the organization’s entry into the war not as a strategic choice but as an obligation.
Israel’s Response: Dahiyeh Under Attack
Israel’s retaliatory strikes targeted Dahiyeh, the densely populated southern suburbs of Beirut that serve as Hezbollah’s primary urban stronghold. According to Lebanese authorities, the strikes killed senior Hezbollah leaders along with dozens of civilians.
The toll was significant: 52 people killed and 154 wounded in Lebanon on March 2 alone. The strikes on Dahiyeh followed the pattern established during previous Israeli operations against Hezbollah — targeting leadership figures in residential areas with significant collateral damage to surrounding buildings and civilian populations.
Ceasefire Declared Over
The United States communicated directly to the Lebanese government that the November 2024 ceasefire was over, formalizing what Hezbollah’s attack had already made apparent. Washington went further, demanding that Lebanon officially designate Hezbollah as a terrorist organization — a demand that struck at the heart of Lebanon’s complex sectarian political arrangements.
The Lebanese government subsequently outlawed Hezbollah’s security and military activities, a largely symbolic gesture given the group’s deep integration into Lebanon’s political and social fabric. The decision reflected the enormous pressure being exerted on Beirut by Washington rather than any genuine shift in the Lebanese government’s capacity to enforce such a ban.
Evacuation Orders and Mass Displacement
Israel issued evacuation warnings for more than 50 towns in southern Lebanon and the Bekaa Valley, signaling its intention to conduct sustained military operations across a wide geographic area. The warnings triggered immediate mass displacement, with scenes reminiscent of the catastrophic events of September 2024, when approximately 500 people were killed and one million displaced in a single day during a previous Israeli escalation.
Lebanese civilians, many of whom had only recently returned to their homes after the 2024 displacement, found themselves fleeing northward again. Roads out of southern Lebanon and the Bekaa Valley were choked with vehicles and families carrying what possessions they could manage.
The Strategic Calculus
Hezbollah’s decision to enter the conflict reflected a calculation about organizational survival and ideological commitment. The group’s relationship with Iran — its primary benefactor, arms supplier, and ideological partner — made neutrality in the face of Khamenei’s assassination functionally impossible.
For Israel, the opening of the Lebanon front presented both a strategic challenge and an opportunity. A two-front war strained military resources, but Israeli military planners had long argued that any comprehensive campaign against Iran would eventually require dealing with Hezbollah’s missile arsenal pointed at northern Israel.
Iranian Backing
Iran’s President Masoud Pezeshkian stated on March 2 that revenge for Khamenei’s killing was a “duty and legitimate right,” language that effectively endorsed Hezbollah’s attack and signaled that Iran expected its regional allies to participate in the conflict.
The IRGC had spent decades building Hezbollah into the most capable non-state military force in the Middle East, supplying it with an estimated arsenal of 150,000 missiles and rockets. That investment was now being activated in what Iran framed as an existential defense.
Bahrain: Collateral Damage Continues
The same day, the conflict’s toll on Gulf bystanders continued. In Bahrain, an Asian worker was killed by debris from an intercepted missile at Salman Industrial City — a reminder that the war’s casualties extended far beyond the primary combatant nations.
The War Widens
By the end of March 2, the conflict had expanded from a bilateral US-Israeli campaign against Iran into a war spanning at least three active fronts: Iran itself, the Gulf states hosting US forces, and now Lebanon. The geographic scope of the fighting, the number of countries affected, and the casualty toll were all escalating at a pace that outstripped the predictions of even pessimistic analysts.
With Hezbollah now fully engaged, the prospect of a rapid resolution to the conflict appeared increasingly remote.
