Israel expands invasion of southern Lebanon – as it happened

The Middle East is currently witnessing a massive escalation in military activity as Israel officially expands its ground invasion of southern Lebanon. Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz have signaled a significant shift in strategy, moving from limited, targeted raids to a broader campaign aimed at establishing a permanent security buffer zone. This expansion follows weeks of intense cross-border exchanges with Hezbollah and a widening regional conflict that now involves direct strikes between Israel, the United States, and Iran. As the Israel Defense Forces (IDF) push deeper into Lebanese territory toward the Litani River, the humanitarian toll is mounting, with reports of significant civilian casualties and massive displacement of the local population.

Featured Snippet: Israel has expanded its invasion of southern Lebanon to establish a security buffer zone extending up to the Litani River, approximately 30 kilometers north of the border. Prime Minister Benjamin Netanyahu announced the move to definitively thwart Hezbollah's invasion threat and push anti-tank missile fire away from Israeli communities. The operation involves thousands of IDF troops from multiple divisions, including the 146th and 810th brigades, and has resulted in the destruction of key infrastructure, including all bridges crossing the Litani. Lebanon has responded by expelling Iran's ambassador, while the international community warns of a deepening humanitarian crisis with over 1,100 dead and a million people displaced.

Netanyahu Orders Deeper Penetration into Lebanese Territory

On Sunday, March 29, 2026, Prime Minister Benjamin Netanyahu issued a direct order to the Israeli military to widen its operations in southern Lebanon. Speaking from the IDF Northern Command Headquarters in Safed, Netanyahu emphasized that the current security situation required a fundamental change. He stated that the expansion of the "security buffer zone" is essential to protect northern Israeli residents who have faced near-constant missile and drone fire since the escalation began on March 2.

The Prime Minister's announcement marks a departure from earlier descriptions of "limited" operations. By ordering troops deeper into the territory, the Israeli government is effectively seeking to dismantle Hezbollah's infrastructure across three distinct lines of defense. The goal is to push the Iran-backed group's anti-tank capabilities beyond the reach of the border, creating a physical gap that prevents easy infiltration or short-range bombardment.

Defense Minister Israel Katz Outlines the Litani River Objective

Defense Minister Israel Katz provided further clarity on the military's geographical goals, explicitly naming the Litani River as the new forward line for the IDF. The Litani River, located roughly 20 to 30 kilometers north of the Israeli border, has long been a strategic marker in regional conflicts. Katz noted that the IDF would maintain control over the bridges and the surrounding security zone to ensure that Hezbollah operatives cannot return to the border region.

In a move that has drawn comparisons to military strategies used in Gaza, Katz suggested that border villages are being systematically cleared and demolished. This "Gaza model" involves the destruction of buildings and infrastructure used by militants to ensure the area cannot be quickly reoccupied. The Defense Minister confirmed that several bridges over the Litani have already been destroyed to sever Hezbollah's supply lines from the north.

The Humanitarian Impact: UNICEF Warns of Rising Child Deaths

As the military campaign intensifies, international humanitarian organizations are sounding the alarm regarding the civilian cost. UNICEF has reported that Israeli attacks in Lebanon have killed at least 121 children since early March. Furthermore, the conflict has displaced over 370,000 children from their homes, contributing to a total displaced population in Lebanon exceeding one million people.

The Lebanese Health Ministry reports that the death toll has surpassed 1,100 people, including women, children, and medical personnel. The World Health Organization (WHO) has specifically highlighted the targeting of medical facilities, noting that several paramedics have been killed in strikes on ambulances. The destruction of medical warehouses and the ongoing bombardment of residential areas in Beirut and southern Lebanon have created a desperate situation for those unable to flee the combat zones.

Military Action Category	Details and Objectives
Primary Objective	Establishment of a 30km security buffer zone up to the Litani River.
Forces Deployed	Multiple divisions including 146th, 810th, and 769th brigades.
Infrastructure Targets	Bridges over Litani River, weapon depots, and border village buildings.
Humanitarian Status	Over 1,100 dead, 1 million displaced, and 121 children killed.

Hezbollah Vows Resistance Against Existential Threat

Hezbollah has responded to the Israeli expansion by declaring the move an "existential threat" to the Lebanese state. Senior lawmaker Hassan Fadlallah stated that the group has no choice but to confront the "aggression" and cling to the land. Despite the loss of several senior leaders in previous months, Hezbollah continues to fire hundreds of rockets daily, although many are now directed at IDF forces operating within Lebanese territory rather than across the border into Israel.

The group remains a potent force in the south, utilizing a network of tunnels and fortified positions in border villages. Analysts suggest that the Israeli occupation of southern Lebanon could fuel long-term support for Hezbollah, as the group often positions itself as the primary defender of Lebanese sovereignty. The ongoing ground clashes in towns like Khiam and Qawzah indicate that the IDF faces significant resistance as it attempts to move northward.

Lebanon Expels Iranian Ambassador Amid Internal Tensions

In a surprising diplomatic development, the Lebanese government has declared the Iranian ambassador, Mohammad Reza Shibani, persona non grata. This unprecedented move reflects a growing rift between the Lebanese state and its traditional backers in Tehran. Prime Minister Nawaf Salam has urged Hezbollah to halt its attacks, arguing that the defense of Iranian interests should not come at the expense of Lebanese lives and stability.

The expulsion of the ambassador is seen as an attempt by the Lebanese government to assert its independence and avoid being completely subsumed into the wider war between the U.S., Israel, and Iran. However, Hezbollah has condemned the decision, claiming it serves Israeli interests and deepens domestic divisions within a country already reeling from economic and military crises.

Regional Context: The U.S.-Israel War on Iran

The invasion of Lebanon is inextricably linked to the broader conflict involving the United States and Iran. President Donald Trump has continued to delay ultimatums for Iran to open the Strait of Hormuz, while U.S. and Israeli forces have conducted strikes on Iranian territory. Iran has retaliated with waves of missiles and drones targeting Israeli cities like Tel Aviv and U.S. interests in the Persian Gulf.

Reports suggest the Pentagon is considering a "final blow" against Iran, which could include a ground invasion or a blockade of major oil terminals like Kharg Island. In this context, the Lebanese front is seen by Israel as a necessary "flank" operation to eliminate Iran's most powerful regional proxy, Hezbollah, while the primary conflict focuses on Tehran's nuclear and military infrastructure.

The Associated Press Defines the Conflict as an Invasion

The Associated Press (AP) recently updated its terminology to officially describe the Israeli military action in Lebanon as an "invasion." This decision was based on several factors, including the broadening scope of the attack, the deployment of thousands of troops, the intent to seize and hold territory, and the extent of casualties. This is the fifth time in 50 years that Israel has invaded its northern neighbor, following actions in 1978, 1982, 2006, and 2024.

Using the term "invasion" highlights the significance of the military crossing into a sovereign nation with the intent to establish a long-term presence. The AP noted that while "incursion" might describe limited raids, the current scale of the operation, particularly the creation of a permanent buffer zone and the displacement of residents, meets the international criteria for an invasion.

Historical Echoes: The 18-Year Lebanese Mud

Veterans of Israeli diplomacy and military history are warning of a return to the "Lebanese mud." Israel previously occupied southern Lebanon from 1982 to 2000, a period marked by significant casualties and the eventual rise of Hezbollah. The 18-year occupation ended with a withdrawal that many in Israel vowed never to repeat. However, the current government argues that the threat posed by Hezbollah's advanced missile arsenal leaves them with no other choice.

Critics argue that history is repeating itself, with Israel seeking to shape the region's politics through force. The "security zone" logic used in the 1980s is being reapplied today, but with a much more powerful and entrenched enemy. The risk of a protracted, indefinite stay in southern Lebanon is high, especially as far-right members of the Israeli cabinet openly discuss the possibility of annexation.

Conclusion

The expansion of Israel's invasion into southern Lebanon represents a pivotal moment in the current Middle Eastern crisis. By committing to a deep security buffer zone and moving toward the Litani River, Israel has signaled that it is prepared for a prolonged occupation to ensure the safety of its northern borders. However, this move comes with immense risks, including a worsening humanitarian catastrophe, the potential for a long-term guerrilla war with Hezbollah, and the possibility of a full-scale regional conflagration involving Iran and the United States. As the world watches the events unfold, the echoes of past conflicts in Lebanon serve as a grim reminder of the difficulty of achieving lasting peace through territorial conquest.
