Operation Litani (1978) Operation Litani (14–21 March 1978) was an Israeli military intervention into southern Lebanon prompted by cross-border attacks by Palestine Liberation Organization (PLO) factions and the Coastal Road massacre. The incursion precipitated an armed confrontation involving Israeli Defence Forces leadership, Lebanese militias, and regional actors, and led to the United Nations Security Council adoption of resolutions creating United Nations Interim Force in Lebanon (UNIFIL).

Background

In the 1970s the presence of armed Palestinian groups in southern Lebanon, including factions of the Palestine Liberation Organization associated with leaders such as Yasser Arafat and organizations like Fatah and Popular Front for the Liberation of Palestine, escalated tensions along the Blue Line (Lebanon–Israel) and the Israel–Palestine conflict. The Coastal Road massacre carried out by operatives linked to Fatah on 11 March 1978 prompted an Israeli government decision led by officials from Likud and the office of Menachem Begin to authorize a cross-border response targeting PLO infrastructure, bases in villages such as Rmeish and Qlaiaa, and transit routes leading to Beirut. Lebanon’s internal strife, exacerbated by the Lebanese Civil War and factions including Phalangist Party and Amal Movement, complicated any Lebanese central authority response under President Elias Sarkis and military commanders of the Lebanese Armed Forces.

Forces and Commanders

The Israeli operation was executed by elements of the Israel Defence Forces including units from the Northern Command (Israel), infantry brigades, armor from the Golani Brigade and Paratroopers Brigade (Israel), and artillery and air support from the Israeli Air Force. Political and military direction involved Prime Minister Menachem Begin, Defense Minister Ezer Weizman, and IDF Chief of Staff Mordechai Gur. Opposing forces comprised Palestine Liberation Organization units of assorted factions, local Lebanese militias including the Kataeb Party (Phalangists) and South Lebanon Army, and irregular armed groups aligned with leaders such as Elie Hobeika and commanders operating under varying loyalties amid the Lebanese Civil War fracturing of authority. International actors monitoring the engagement included delegations from the United Nations and envoys representing United States diplomacy under President Jimmy Carter and advisors from the Carter administration.

Course of the Operation

On 14 March Israeli forces crossed the Israel–Lebanon border and pushed northward to the Litani River, aiming to clear a buffer zone and displace PLO operatives from launch sites linked to attacks on Haifa and the Coastal Road massacre. The IDF advance involved combined-arms maneuvers using armor, infantry, airborne insertions, and airstrikes by the Israeli Air Force targeting refugee camps and logistics nodes suspected of harboring militant cells. Engagements occurred near population centers including Saidon (Sidon), Tyre, and villages in the South Governorate (Lebanon), provoking clashes with PLO fighters and local militias. Amid international pressure from representatives of the United States, United Kingdom, and the United Nations Security Council, a ceasefire and the deployment of UN forces were negotiated, culminating in Security Council resolutions that authorized the establishment of UNIFIL to confirm Israeli withdrawal and assist the Lebanese Armed Forces.

Casualties and Damage

Combat operations produced significant human and material tolls: estimates reported several hundred killed and thousands wounded among combatants and civilians, with damage to civilian infrastructure in southern towns and to refugee camps associated with Palestinian refugees. Reports referenced destruction to homes, schools, and health facilities in municipalities around Tyre and Sidon, and disruptions to humanitarian supplies provided by organizations such as United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA). Military losses included IDF personnel casualties and equipment attrition, while PLO units sustained losses in fighters and materiel, contributing to shifts in force disposition.

International Reaction and Diplomacy

The incursion drew immediate condemnation and diplomatic activity at the United Nations Security Council where representatives from states including the United States, Soviet Union, France, and United Kingdom engaged in debates over sovereignty, self-defense, and proportionality. The Council adopted resolutions calling for ceasefire, Israeli withdrawal, and creation of a multinational UN presence; these measures involved coordination among envoys such as Andrew Young representing United States foreign policy interests and representatives from Ambassador to the UN (USA) offices. Arab League members including Egypt and Syria denounced the operation, while Israel defended its actions as retaliation against PLO terrorism. International humanitarian organizations, including International Committee of the Red Cross and UNRWA, pressed for access to affected civilians.

Aftermath and Consequences

The operation ended with Israeli forces partly withdrawing and the deployment of United Nations Interim Force in Lebanon tasked to monitor cessation of hostilities and facilitate return of displaced persons; the presence of UNIFIL reshaped security dynamics in southern Lebanon. Politically, the operation influenced Israeli domestic politics involving Menachem Begin and debates within Likud and oppositional parties, affected PLO strategy and leadership decisions by figures such as Yasser Arafat, and contributed to subsequent cross-border violence that fed into later events like the 1982 Lebanon War. The humanitarian and infrastructural damage compounded challenges facing the Lebanese Republic amid the Lebanese Civil War, and the operation remained a reference point in discussions of United Nations peacekeeping mandates and regional diplomacy involving Syria, Israel, and Western powers.
