Fragile US-Iran Ceasefire Under Strain After Massive Israeli Airstrikes in Lebanon

A fragile two-week ceasefire between the United States and Iran, brokered by Pakistan and announced by President Donald Trump late on Tuesday, came under immediate strain on Wednesday after Israel launched what it described as its largest coordinated strike on Lebanon, killing at least 254 people and wounding more than 1,100, according to Lebanon's civil defence service. The Israeli military said it struck more than 100 Hezbollah command centres and military sites in a 10-minute assault targeting Beirut, the Bekaa Valley, Mount Lebanon, Sidon, and villages in southern Lebanon. The highest single-day death toll of the Israel-Hezbollah conflict fell on Beirut alone, where 91 people were killed according to Lebanon's civil defence. The strikes exposed a fundamental disagreement at the heart of the ceasefire: the United States and Israel insist the truce covers only the direct US-Iran conflict, while Iran, Lebanon, and Pakistan — the mediating party — maintain it was meant to include Lebanon as well. Peace talks scheduled to begin on Saturday in Pakistan now face an uncertain future, with Iran signalling it may refuse to attend.

Vance calls Lebanon dispute a 'legitimate misunderstanding' US Vice President JD Vance, who is set to lead the American delegation at the Pakistan talks, told reporters in Budapest that Iran had misread the scope of the agreement. „I think the Iranians thought that the ceasefire included Lebanon, and it just didn't. We never made that promise.” — JD Vance via TheJournal.ie Vance characterised the disagreement as a "legitimate misunderstanding" and warned that Iran breaking the truce could have "serious consequences," while adding that doing so was "ultimately their choice." President Trump separately confirmed to reporters that Lebanon was not included in the deal, attributing the exclusion to Hezbollah's role. Israeli Prime Minister Benjamin Netanyahu said Israel had its "finger on the trigger" and was prepared to return to full fighting "at any moment," while also stating the ceasefire was "not the end" of Israel's military campaign against Iran, calling it "a stop on the way to achieving all of our objectives." Israeli Defence Minister Israel Katz said Israel had "insisted on separating the war with Iran with the fighting in Lebanon in order to change the reality in Lebanon." Lebanese Prime Minister Nawaf Salam accused Israel of killing unarmed civilians and declared Thursday a national day of mourning. 254 (people killed) — Lebanese civil defence death toll from April 8 strikes

Iran threatens to walk away from Saturday's Pakistan talks Iranian Parliament Speaker Mohammad Bagher Ghalibaf, who is expected to co-lead Tehran's delegation alongside Foreign Minister Abbas Araghchi, said proceeding with negotiations was "unreasonable" given the conditions on the ground. „In such a situation, a bilateral ceasefire or negotiations were unreasonable.” — Mohammad Bagher Ghalibaf via RTE.ie Ghalibaf accused the United States of violating Iran's framework on three counts: continued Israeli strikes in Lebanon, a drone entering Iranian airspace, and what he described as denied enrichment rights. He wrote on X that "the very 'workable basis on which to negotiate' has been openly and clearly violated, even before the negotiations began." Iranian Foreign Minister Abbas Araghchi stated that Washington must choose between the temporary ceasefire and allowing Israel to continue its operations in Lebanon, framing the situation as a choice between diplomacy and war by proxy. Iranian President Masoud Pezeshkian told French President Emmanuel Macron that establishing a ceasefire in Lebanon had been "one of the key conditions of Iran's 10-point plan." Pakistan's Prime Minister Shehbaz Sharif, whose country mediated the truce, called on all parties to exercise restraint, confirming that violations of the ceasefire had already been reported.

The US-Israel war on Iran, known as Operation Epic Fury, began on February 28, 2026, with coordinated strikes that killed Iran's Supreme Leader Ali Khamenei. Mojtaba Khamenei, Ali's son, was appointed Supreme Leader on March 9, 2026. The current conflict between Israel and Hezbollah in Lebanon began after the militant group responded to Ali Khamenei's death by firing missiles into Israel from Lebanese territory, according to The Irish Times. The ceasefire announced on April 7-8, 2026, was the first formal pause in hostilities since the war began, brokered with Pakistani mediation while negotiations on a longer-term settlement were set to continue.

Strait of Hormuz status contested, Gaza contractors fire on civilians The status of the Strait of Hormuz remained contested on Wednesday, with Iranian state media reporting it was "fully closed," while Iran's official broadcaster indicated ships could pass under Iranian coordination. Iran had agreed as part of the ceasefire to allow vessels through the strait for two weeks, but according to Iran's Fars news agency, oil tanker passage was halted because of Israel's strikes on Lebanon. Ship-tracking firm Kpler reported that no oil tankers had crossed the strait since the truce began, with only a few merchant vessels carrying dry cargo recorded passing through on Wednesday. The uncertainty rattled energy markets: oil prices fell 14 percent to settle near $95 per barrel after dropping as low as $90.40, while world stock indexes surged. Gulf states reported continued Iranian missile and drone attacks even after the ceasefire announcement, with Kuwait reporting 28 drone attacks, the United Arab Emirates saying it engaged 17 ballistic missiles and 35 drone attacks, and Saudi Arabia saying it intercepted nine drones, according to The New York Times. Separately, American contractors guarding aid distribution sites in Gaza were reported by the Associated Press to be using live ammunition and stun grenades against Palestinians seeking food, with two contractors speaking anonymously to AP saying they came forward because they were disturbed by what they considered dangerous and irresponsible practices.
