April 9, 2026 — A tenuous two-week ceasefire brokered by the United States, Israel and Iran showed signs of collapse on Thursday as heavy Israeli strikes struck across Lebanon and Tehran signaled it could resume hostilities. The fighting has intensified regional tensions, alarmed international officials and produced a heavy civilian toll.
Widespread strikes in Beirut and beyond
Israeli air raids on Wednesday struck commercial and residential areas in central Beirut and other parts of Lebanon. Lebanese authorities said the raids had killed 203 people and wounded more than 1,000, prompting a national day of mourning and large-scale displacement. Health Minister Rakan Nassereddine described the victims as “martyrs” and highlighted the immense civilian suffering caused by the operations.
Israel: targets were Hezbollah
Israeli officials said the strikes were aimed at Hezbollah positions and operatives. Prime Minister Benjamin Netanyahu pledged to keep striking the Iran-backed group “wherever necessary” to protect communities in northern Israel. The Israel Defense Forces said it had “eliminated” Ali Yusuf Harshi, identified as a close associate and adviser to Hezbollah leader Naim Qassem; Lebanese security sources reported an attack on an apartment where Harshi was believed to be staying. Hezbollah did not immediately confirm the death. Qassem assumed Hezbollah’s leadership in October 2024 after Hassan Nasrallah was killed in a 2024 Israeli strike.
Hezbollah and Iran respond
Hezbollah reported launching rockets into Israel in retaliation for what it called a breach of the ceasefire, citing strikes toward northern localities including the kibbutz of Manara. Iran, which had earlier agreed a truce with the US and Israel, insisted the agreement should cover Lebanon as well and accused Israel of violating the deal. US and Israeli officials countered that strikes targeting Hezbollah in Lebanon were not included in the ceasefire, a key discrepancy that diplomats warned could undermine the pause in fighting.
International alarm and UN warnings
UN Secretary-General António Guterres warned that continued Israeli operations in Lebanon posed a “grave risk” to the ceasefire and urged an immediate halt to hostilities. Analysts and diplomatic sources said excluding Lebanon from the truce or interpreting the terms differently left the agreement “on the verge of collapse.” European and other world leaders urged restraint and called for the ceasefire to be broadened to include Lebanon to avoid wider escalation.
Iran signals broader measures, maritime threats
Iranian state media and officials indicated Tehran might return to broader hostilities if the truce’s terms were not respected. Iranian authorities published maps suggesting the Islamic Revolutionary Guard Corps had placed sea mines in the Strait of Hormuz and proposed alternate shipping routes closer to Iran’s coast, including passages near Larak Island. It was unclear whether mines had been removed or whether Iran would permit commercial transit; the US cautioned that any shutdown of the strait would be “completely unacceptable.”
Diplomacy continues amid violence
Diplomatic efforts persisted alongside the fighting. British Prime Minister Keir Starmer visited the UAE to press for consolidation of the ceasefire and measures to reopen the Strait of Hormuz; Foreign Secretary Yvette Cooper urged that Lebanon be included in any extension of the truce. Spain said it would reopen its embassy in Tehran, with Foreign Minister José Manuel Albares framing the move as support for peace and criticizing Israel’s strikes in Lebanon as violations of international law.
Saudi-Iran contacts and mediation
Saudi Arabia and Iran spoke by phone for the first time at the foreign minister level since the war began, discussing ways to ease tensions and restore stability. An Iranian delegation was due in Islamabad for talks with US interlocutors based on a 10-point proposal from Tehran, with Pakistan continuing a mediating role.
US posture and economic warnings
US President Donald Trump said American forces would remain in the region until a “real agreement” was secured and warned of tougher strikes if the deal unraveled. He also threatened 50% tariffs on countries supplying weapons to Iran, though the legal basis and feasibility of such measures were unclear.
Humanitarian and commercial impacts
The strikes in Lebanon drew condemnation over civilian casualties and raised fears of a humanitarian catastrophe. UN officials and rights groups described the scale of killing and displacement as horrific. Airlines, including Air France, extended suspensions of flights to parts of the Middle East, while other carriers also canceled routes, disrupting commercial travel. Concerns about intermittent closures or threats to the Strait of Hormuz heightened anxiety over global shipping and the safety of seafarers.
Developments inside Iran
In Tehran, crowds marked the end of the 40-day mourning period for former Supreme Leader Ayatollah Ali Khamenei, who was killed in a February strike. State television showed mourning crowds and broadcast plans for a prayer service, although it was unclear who would lead it. Mojtaba Khamenei, elected as the new supreme leader, had not yet appeared publicly since his elevation.
Outlook
With differing interpretations of the ceasefire and continued military activity in Lebanon, diplomats said the truce remained fragile. Observers warned that further strikes, retaliatory rocket fire and competing diplomatic narratives could quickly erode the pause and risk a broader regional confrontation unless parties clarify terms and restrain from actions that would escalate the conflict.
