Iran Reimposes Strait of Hormuz Closure, Accuses US and Israel of Violating Post-War Agreement

Tehran, June 2026 : Iran on Saturday announced the renewed closure of the strategically vital Strait of Hormuz, citing what it described as violations of a recently signed Memorandum of Understanding (MoU) by the United States and Israel. The decision comes only days after Tehran and Washington agreed to reopen the crucial maritime corridor following months of regional tensions and military confrontations.

According to reports carried by Iran’s semi-official Mehr News Agency, the announcement was made by the Khatam al-Anbiya Central Headquarters, the country’s top joint military command. Iranian authorities said the move was prompted by what they termed an “explicit breach” of the first provision of the post-war agreement, along with continuing military actions in southern Lebanon that Tehran claims contradict the spirit and terms of the ceasefire arrangement.

In its statement, the military headquarters declared that vessel traffic through the Strait of Hormuz would be suspended until further notice. Officials argued that the alleged actions of the United States and Israel had undermined commitments made under the agreement designed to end hostilities and restore stability in the region.

The Memorandum of Understanding was signed on June 18 through a simultaneous digital process involving Iranian President Masoud Pezeshkian and US President Donald Trump. The agreement was hailed at the time as a significant diplomatic breakthrough aimed at reducing tensions after months of conflict.

Under the terms of the accord, the first article reportedly called for the immediate and permanent cessation of military operations involving Iran, the United States, and their respective allies across multiple regional fronts, including Lebanon. It also committed all parties to refrain from future military action or threats of force.

Iranian officials now contend that these commitments have not been honored. They pointed specifically to developments in Lebanon, claiming that ongoing military activities constitute a direct violation of the agreement’s core provisions.

The latest announcement represents a dramatic reversal from measures introduced only a day earlier. On Friday, Iran unveiled a new regulatory framework governing maritime traffic through the Strait of Hormuz. The regulations required vessels to obtain permits, insurance coverage, and advance authorization before entering the waterway. Those rules were introduced following the reopening of the strait under the US-Iran agreement and were intended to regulate commercial shipping and enhance maritime security.

The regulations were overseen by the newly established Persian Gulf Strait Authority (PGSA), an organization created as part of the broader framework to manage navigation through the strategically important passage.

The Strait of Hormuz remains one of the world’s most critical energy corridors, serving as a transit route for a significant share of global oil and liquefied natural gas exports. Any disruption to shipping through the strait is closely watched by international markets due to its potential impact on energy supplies and global trade.

Earlier this week, the US Central Command announced that American forces had ended enforcement of maritime restrictions around Iranian ports and coastal areas. The command stated that US military blockade operations had ceased and that commercial vessels were free to enter and leave Iranian ports without interference.

However, US officials also noted that American naval forces would remain in the region to monitor compliance with the agreement and ensure that its provisions continued to be observed.

Iran’s latest decision to shut the strait once again raises fresh concerns about regional stability and the future of the recently signed agreement, which had been viewed as a major step toward reducing tensions in the Gulf and restoring confidence in international shipping routes.
