Iran will withdraw from its two-week ceasefire with the United States if Israel continues to strike Lebanon, an informed source told Iran’s semi-official Tasnim News Agency on Wednesday evening.

“Iran will withdraw from the agreement if violations of the ceasefire by the Zionist regime continue through attacks on Lebanon,” the source said, according to Ada Derana. Tehran has described the Israeli bombardment as a direct breach of the Pakistan-brokered truce, arguing that a halt to fighting on all fronts — including against Lebanon’s Hezbollah — was part of the framework Washington accepted.

Israel launched what it described as its largest coordinated wave of airstrikes across Beirut, the Bekaa Valley and southern Lebanon earlier the same day, hitting more than 100 sites. Lebanese authorities said at least 1,530 people have been killed and 4,812 injured since the current Israeli offensive began. Tel Aviv has publicly argued that Lebanon is not covered by the US–Iran ceasefire framework.

The Iranian warning came only hours after Tehran had already halted oil tanker traffic through the Strait of Hormuz in response to the Lebanon strikes, undoing most of the market relief the ceasefire had produced earlier in the day.

For Sri Lanka, the prospect of a formal Iranian withdrawal from the truce is a direct threat to an already fragile fuel pipeline. The island’s nine April oil shipments, its QR-code rationing regime and the Rs. 100 billion presidential relief package all assume a permanently reopened Hormuz. A collapse of the ceasefire would likely reinstate closures, push up global crude and refined-product premiums, and complicate the automatic tariff mechanism the government announced this week.

Pakistan’s first formal US–Iran peace talks are still scheduled to begin in Islamabad on Friday, with Tehran publicly confirming its delegation will attend.
