Iran closes Strait of Hormuz again in response to Israeli attacks in Lebanon; Terms of tentative ceasefire remain unclear; Arab League chief accuses Israel of undermining peace

Iran closed the Strait of Hormuz again on Wednesday in response to Israeli attacks on the militant group Hezbollah in Lebanon, casting doubt on whether an already precarious ceasefire that would end more than a month of war will hold.

The United States and Iran both claimed victory after reaching the deal, and world leaders expressed relief even as more and more drones and missiles hit Iran and the Arab Gulf states.

Israel has also intensified its attacks in Lebanon, hitting several commercial and residential areas in Beirut without warning. At least 112 people were killed and hundreds were injured in one of the deadliest days in the latest war between Israel and Hezbollah.

The new violence threatened to undo what US Vice President JD Vance called a “fragile” deal.

“Aggression against Lebanon is aggression against Iran,” General Seyed Majid Mousavi, space commander of Iran’s Revolutionary Guards, wrote on X. He warned that Iranian forces were preparing a “heavy response” without revealing details.

US Defense Secretary Pete Hegseth said that US and Israeli forces had achieved a “Capital V military victory” and that the Iranian military no longer posed a significant threat to US forces or the region.

Iran’s military said the country forced Israel and the US to accept the “proposed terms and surrender.”
