Iran’s Supreme Leader, Mojtaba Khamenei, has issued a stern warning to the United States, declaring that Iran and its allies would teach Washington “unforgettable lessons” as hostilities between the two countries continue to intensify following renewed military strikes and the collapse of a recent truce.
In a written statement released on Saturday through his official channels, Khamenei accused the United States of repeatedly violating a memorandum of understanding signed between Tehran and Washington, saying the alleged breaches had demonstrated that U.S. President Donald Trump’s commitments could not be trusted.
“The repeated breaches of the agreement by the Great Satan regarding the memorandum of understanding signed by the presidents of Iran and the United States have once again laid bare a fundamental truth: the signature of the U.S. president is utterly worthless and devoid of credibility,” the statement said.
The Iranian leader accused Washington of pursuing a policy based on “coercion, domination and brutality” and warned that continued U.S. military operations would be met with stronger retaliation.
“The American enemy seeks to ignite wars. It must realise that the Iranian people and the Resistance Front will teach it unforgettable lessons,” Khamenei said, while calling on Iranians to maintain national unity in the face of what he described as external aggression.
His remarks came hours after two U.S. service members were killed and another declared missing following Iranian missile and drone strikes on an American military installation in Jordan, marking one of the deadliest attacks on U.S. forces since the latest round of fighting began.
The renewed exchange of hostilities follows the collapse of a ceasefire agreement reached only weeks ago after Washington resumed airstrikes against Iranian military targets.
Since then, both countries have exchanged attacks, with Iran targeting U.S. military facilities and allied infrastructure across the Gulf, while the United States has continued bombing Iranian military installations, logistics hubs and surveillance sites.
Iran’s Islamic Revolutionary Guard Corps (IRGC) has also warned neighbouring Gulf states hosting American military bases to prepare for what it described as “corresponding and proportional” responses if they continue to support U.S. operations.
The escalating conflict has heightened fears of a wider regional war, with repeated attacks threatening commercial shipping in the Strait of Hormuz, disrupting energy infrastructure and raising concerns over global oil supplies.
International observers have warned that continued military escalation could further destabilise the Middle East and complicate efforts to revive diplomatic engagement between Tehran and Washington.
