Hezbollah continues fighting in southern Lebanon

Hezbollah and Israel are still fighting in southern Lebanon even though a U.S.-brokered ceasefire took effect on April 17 and was later extended. The basic problem is that the deal never really settled the hardest question — who controls the strip of southern Lebanon where Israeli troops are still deployed and Hezbollah still operates. By early May, that gray zone was back to daily fire, evacuation warnings, and airstrikes. ### Why didn’t the ceasefire stick? Because it was narrow and conditional from the start. The agreement paused attacks and opened talks between Israel and Lebanon, but it also left Israel claiming a broad right to act in self-defense at any time. It also leaned on the Lebanese state to curb Hezbollah — something Beirut has struggled to do for years. So the truce was less a clean stop than a test of whether the Lebanese army and government could fill space Hezbollah had dominated. ### What changed after April 17? For a few days, friction dropped. Then it started climbing again in late April. Israeli commanders said Hezbollah resumed attacks on troops and northern communities, while Hezbollah treated Israeli operations inside southern Lebanon as fair game. On April 29, IDF chief Eyal Zamir told troops there was “no ceasefire” on that front and said the military would keep operating until northern Israeli communities were secure. That was basically the public admission that the truce had stopped functioning as a real ceasefire in the south. ### What’s happening on the ground now? A mix of airstrikes, artillery, drone attacks, and warnings for civilians to leave villages. On May 6, Israeli strikes in southern and eastern Lebanon killed at least six people, including four members of one family in Zellaya, and Israel issued evacuation orders for 12 southern villages. Hezbollah said it had attacked Israeli soldiers the same day. So this is not diplomatic drift — it is active combat, just under a label that still says “ceasefire.” ### Why is southern Lebanon the sticking point? Because that’s where the military map and the political map no longer match. Israel is still holding a buffer area in parts of the south and says it will not leave until the threat is removed. Hezbollah, meanwhile, is weaker than it was before but still armed, still present, and still able to hit Israeli forces with drones and other attacks. If one side thinks the ceasefire applies only north of the Litani River and the other thinks any Israeli troop presence is a live target, you get exactly this kind of “truce that isn’t one.” ### Where does the Lebanese government fit? In theory, at the center. The April deal said Lebanon’s security forces are the only legitimate armed force and that Hezbollah’s activity must be curtailed. But theory is the easy part. The Lebanese state does not fully control the south, and disarming Hezbollah has been a dead-end political demand for decades. That means every ceasefire depends on a state capacity Lebanon does not yet have. ### Why does the Iran piece matter? Because this front is no longer isolated. The wider 2026 U.S.-Israel-Iran conflict weakened Iran and scrambled regional diplomacy, but it also made every Iranian-aligned front more volatile. The Commons Library briefing notes that the Lebanon ceasefire sat inside that broader crisis. In plain English — when the region’s main patron network is under pressure, local ceasefires get harder to enforce, not easier. ### Is this a full return to war? Not quite, but that’s the danger. What exists now is an unstable in-between — too much fighting to call it peace, but still enough diplomacy to avoid saying the ceasefire is dead. That kind of limbo is risky because each “limited” exchange creates another reason for escalation. One bad strike, one mass-casualty event, or one failed round of U.S.-mediated talks could turn this back into open war very quickly. The bottom line is simple. The April 17 ceasefire paused the war on paper, but it never resolved control of southern Lebanon. Until that changes, the fighting will keep finding ways to continue.
