Key takeaway

Lebanon carries the human cost of a ceasefire that does not cover it.

As the Islamabad talks concluded on 12 April, IDF (Israel Defense Forces) strikes killed 18 people in southern Lebanon, 13 of them in the village of Tefayta. The strikes continued a pattern that began on ceasefire day itself: on 7 April, hours after the Iran ceasefire was announced, Israel struck more than 100 targets across Lebanon, killing at least 303 people and wounding over 1,150.

Benjamin Netanyahu declared the ceasefire "does not bind Israel in Lebanon." Trump supported that position. The 98th Division deployed into southern Lebanon during the ceasefire window, joining four divisions already operating there: the 36th, 91st, 146th, and 162nd . Five IDF divisions are now active in a country that is not formally part of any ceasefire agreement.

Iran formally accused the US of ceasefire violations and warned that its allies are "an inseparable part" of the ceasefire, with violations carrying "explicit costs and strong responses." Hezbollah had fired a missile at Tel Aviv days earlier, triggering air-raid sirens across three Israeli cities; it was intercepted . Iran listed Lebanon as a precondition at Islamabad. It was not resolved.

Lebanon has no seat at the negotiations, no ceasefire of its own, and no voice in the terms. It is the active front in a war whose ceasefire explicitly excludes it. Beirut bears the cost of strikes that Iran cites as violations. For Lebanese civilians, the ceasefire is something that happened to other people.

Deep Analysis

In plain English

The ceasefire announced on 7 April was between the US and Iran. It said nothing about Lebanon, where Israeli forces have been fighting Hezbollah, an Iranian-backed armed group, for months. While US and Iranian diplomats were talking in Islamabad, Israeli strikes killed 18 people in southern Lebanon. Iran had told the talks: Lebanon must be part of any deal. The US and Israel said Lebanon is a separate issue. This matters because Hezbollah is Iran's most important regional partner. For Iran to accept a deal that leaves Lebanon out would be politically very difficult at home, it would look like Iran abandoned an ally. So what happens in Lebanon has a direct effect on whether a nuclear or Hormuz deal is possible.

Deep Analysis

Root Causes

Netanyahu's declaration that the ceasefire 'does not bind Israel in Lebanon' reflects the Israeli government's longstanding position that Lebanese operations are separate from any US-Iran framework. The US accepted this carve-out when it agreed the ceasefire terms, which means the ceasefire was structurally incomplete from day one.

The five IDF divisions currently in southern Lebanon represent a force posture that has no parallel since the 2006 war; the 98th Division's deployment alongside the 36th, 91st, 146th, and 162nd represents the largest Israeli ground commitment in Lebanon in two decades. This is not an incidental border operation, it is a sustained campaign.

What could happen next?

Risk
Iran's formal ceasefire violation accusation over Lebanon operations provides Tehran with a legally-framed pretext to abrogate the ceasefire at any point before 22 April, particularly if IDF operations intensify or a high-profile Hezbollah target is struck.
Consequence
Lebanon has no seat at the Islamabad talks and no ceasefire of its own; even a complete Iran-US nuclear deal would leave the Lebanese conflict unresolved and Hezbollah under active IDF pressure, creating a persistent flashpoint.

Primary parallel: The 2006 Lebanon-Israel war ended with UN Security Council Resolution 1701, which established a ceasefire based on Hezbollah disarmament commitments that were never fulfilled. The current Lebanese front reflects the same structural failure: Israel accepts ceasefires with Hezbollah as temporary pauses rather than permanent settlements.

Counter-parallel: The 1993 Oslo Accords separated the Palestinian track from the Lebanese track, allowing progress on one without resolving the other. The US is attempting the same disaggregation, handling Iran bilaterally while treating Lebanon as a separate Israeli security matter. Iran is explicitly rejecting that disaggregation.

Consensus view: Al Jazeera's analysis and the Carnegie Endowment's assessment both identify Lebanon as the wildcard most likely to collapse the Iran ceasefire entirely: Iran cannot publicly accept a deal that leaves its primary proxy under active military attack, and Israel has no operational incentive to pause Lebanon operations while Iranian nuclear talks are ongoing.

Counter-view: The IDF's continued operations may reflect a deliberate Israeli strategy to maintain pressure during the ceasefire window specifically, calculating that Iran will not abrogate the ceasefire over Lebanon if the nuclear and Hormuz stakes are high enough.

Key tension: Iran's formal accusation that the US is violating the ceasefire by permitting Israeli Lebanon operations creates a legal pretext for Tehran to abrogate the agreement at a time of its choosing, giving Tehran an off-ramp that does not require returning to war.

Different Perspectives

Iran human rights monitors (Amnesty International, Iran HRM, Hengaw)

Monitors documented 30 women held on capital moharebeh charges in a basement prison ward, Benyamin Naqdi's death sentence with a forced-confession broadcast, and 39 political executions since February. Iran's security courts have processed protest cases at uninterrupted wartime tempo regardless of the diplomatic track.

Lloyd's of London (war-risk underwriters)

Lloyd's held its Hormuz war-risk designation at $10-14 million per voyage while Brent fell 19%, maintaining a structural divergence from futures pricing. Underwriters require a UN Security Council resolution or government certification letter, not diplomatic optimism, before de-listing the strait.

Oman (Sultan Haitham's government)

Muscat issued a mine alert in its own territorial waters while denying any Hormuz toll plan after US Treasury threatened sanctions. A suspected mine in Omani waters on the same weekend as US financial pressure forces Muscat to demonstrate sovereignty without appearing to choose sides.

China (PRC)

Beijing sent scholars rather than its defence minister to Shangri-La for the second year running and addressed Taiwan and multilateralism without mentioning Iran. China maintains its bilateral energy corridor protection with Tehran while refusing the diplomatic exposure of a public position at multilateral forums.

Iran Supreme National Security Council

The SNSC framed the unsigned MOU as a 10-point Iranian victory with enrichment already recognised, and the foreign ministry rejected Trump's nuclear conditions within hours. Tehran treats each unsigned day as validation that Iran has retained its stockpile without surrendering it.

Trump administration (CENTCOM/White House)

Trump posted three non-negotiable public conditions while CENTCOM disabled a commercial ship and Hegseth threatened resumed strikes from Singapore. The administration treats the unsigned MOU as leverage to extract maximum Iranian concessions before any ceasefire instrument is committed to paper.
