Iran President Masoud Pezeshkian on Thursday accused Israel of violating the agreement with its renewed military offensive in Lebanon, warning that continued aggression would make negotiations “meaningless”.Pezeshkian, in a sharply worded statement, described Israel’s latest incursion as a “blatant violation” of the initial ceasefire framework and a “dangerous sign of deception” that calls into question the credibility of ongoing diplomatic efforts.“The continuation of these actions will render negotiations meaningless. Our fingers remain on the trigger. Iran will never abandon its Lebanese sisters and brothers,” he said, signalling Tehran’s readiness to escalate if hostilities persist.The warning comes a day after Israel unleashed its heaviest strikes on Lebanon since the conflict began last month, despite a pause in attacks by the Iran-backed group under the ceasefire arrangement.Explosions rocked Beirut and other parts of the country as Israeli forces carried out what they described as the largest coordinated strikes of the war, targeting over 100 Hezbollah command centres and military installations across the capital, the Bekaa Valley and southern Lebanon.Lebanese authorities said at least 254 people were killed and hundreds injured in one of the deadliest days of the ongoing conflict, underscoring the rapidly deteriorating security situation.The escalation has exposed deep ambiguities in the scope of the ceasefire agreed between Washington and Tehran after nearly 40 days of intense hostilities that had pushed the region to the brink of a wider war.Described by Donald Trump as a “double-sided ceasefire”, the two-week arrangement is contingent upon Iran ensuring the “complete, immediate, and safe opening” of the strategically vital Strait of Hormuz—a key artery for global oil supplies.However, Israel has maintained that Lebanon is not covered under the ceasefire framework, effectively creating parallel interpretations of the agreement and complicating efforts to stabilise the region.The divergence has added to uncertainty on the ground, with sporadic violence continuing across multiple theatres even as diplomatic channels remain active.
