Israel Renews Lebanon War as Water Crisis Deepens Across South

Israel launched a renewed military offensive against Lebanon on March 2, 2026, reigniting a conflict that had already devastated the country’s south and triggering what humanitarian organisations describe as a catastrophic water emergency affecting hundreds of thousands of civilians.

Hezbollah broke a 15-month period of restraint on the same day, firing rockets into Israeli territory in retaliation for the killing of Iranian Supreme Leader Ayatollah Ali Khamenei. The rocket fire marked a dramatic escalation following a period in which more than 10,000 ceasefire violations had been recorded without a formal Hezbollah military response.

Within four days of the renewed offensive, Israeli strikes had damaged at least seven critical water sources across Lebanon, including reservoirs, pipe networks, and pumping stations. Those facilities alone had supplied water to nearly 7,000 people in the Bekaa Valley. Infrastructure in Britel, Nabi Chit, and Marjayoun in southern Lebanon sustained direct damage, compounding a water insecurity crisis that predated the latest escalation.

The scale of civilian displacement has been staggering. Israeli bombing campaigns in the days following March 2 forced more than 1.2 million people from their homes across Lebanon. Israeli forces are currently occupying dozens of villages in the south, and Prime Minister Benjamin Netanyahu confirmed in April that Israeli troops are maintaining a security buffer zone extending 10 kilometres — approximately 6.2 miles — into Lebanese territory.

The water situation had already been dire before the latest offensive. A study conducted by the International Committee of the Red Cross in October 2025 across the Bint Jbeil and Marjayoun districts found that 91 percent of households were experiencing moderate-to-high water insecurity, with 57 percent classified as highly water insecure. Israeli strikes had damaged six water facilities in southern Lebanon since 2023, and the renewed campaign has dramatically accelerated that destruction.

Imad Chiri, the ICRC’s water and habitat coordinator, has highlighted the acute danger posed by the targeting of civilian water infrastructure. Under the Geneva Conventions — which Israel ratified in 1951 — the deliberate destruction of objects indispensable to civilian survival, including water installations, is prohibited under international humanitarian law.

Tadesse Kebebew, a legal researcher and project manager at the Geneva Water Hub, has pointed to the legal obligations binding all parties to the conflict. The systematic nature of the damage to water systems has drawn scrutiny from legal and humanitarian experts who argue the pattern cannot be dismissed as incidental.

Lebanon has also accused Israel of obstructing access to water from the Wazzani River, which crosses the Blue Line separating Lebanese and Israeli territory, including through the bombing of pumping stations along the river. The allegations add a further dimension to concerns about the deliberate weaponisation of water access.

Oxfam Lebanon Country Director Bachir Ayoub has warned that the destruction of water infrastructure is pushing already vulnerable communities toward a full-scale public health emergency. Without functioning water systems, the risk of disease outbreaks among displaced populations rises sharply.

Rami Zurayk, professor and chairperson of the Department of Landscape Design and Ecosystem Management at the American University of Beirut‘s Faculty of Agricultural and Food Sciences, has noted that the cumulative damage to Lebanon’s water systems represents not merely a short-term crisis but a long-term threat to the country’s agricultural and ecological stability.

Nadim Farajalla, an environmental engineer and chief sustainability officer at the Lebanese American University in Beirut, has similarly warned that repairing the damaged infrastructure will require sustained international support that Lebanon, already economically fragile, is ill-positioned to provide on its own.

The crisis in Lebanon mirrors patterns documented elsewhere in the region. Israel controls Palestinian access to water in Gaza and has impeded water access for Palestinians in the West Bank, drawing repeated condemnation from international human rights bodies.

This marks the second time in less than two years that Israel has launched a major military campaign in Lebanon, a country still struggling to recover from the economic collapse, the 2020 Beirut port explosion, and the destruction wrought by the previous round of conflict. With displacement surging, water systems failing, and no ceasefire in sight, international humanitarian agencies are warning that the civilian toll of the renewed war is set to deepen significantly in the weeks ahead.
