Iran Ends Agreement After US Strikes, Warns of ‘Unforgettable Consequences’

Iran announced the end of its ceasefire agreement with the United States, arguing that Washington violated the commitments reached after resuming attacks on Iranian territory. The decision marks a new breaking point in a war that began in late February and, despite several attempts at international mediation, once again places the Middle East on the brink of an escalation with unpredictable consequences.

The announcement was accompanied by a harsh message from Iran’s Supreme Leader, Mojtaba Khamenei, who accused U.S. President Donald Trump of breaking the pact and said the Islamic Republic has prepared “unforgettable lessons” for Washington.

His remarks further heighten tensions in a conflict that has already left thousands of casualties, damage to strategic infrastructure, and growing fears of a broader regional confrontation.

Iran ends agreement after US strikes, warns of ‘unforgettable consequences’

Iranian authorities maintain that the memorandum of understanding that led to the ceasefire became void after the U.S. bombings carried out in recent weeks. According to Tehran, those attacks constitute a direct violation of the agreement and demonstrate that the United States failed to honor the commitments made during negotiations facilitated by international mediators.

“The repeated violations by the Great Satan [the United States] of the commitments assumed in the memorandum of understanding signed between the presidents of Iran and the United States have once again shown everyone how useless and invalid the signature of the U.S. president is,” Khamenei said in statements released on his social media accounts and by state television.

Khamenei, who has not appeared in public since his designation as the country’s Supreme Leader last March, also called for national unity and urged both the public and government officials to avoid divisions and internal conflicts in the face of what he described as the “criminal and cunning American enemy.”

Meanwhile, Iranian political authorities reported that U.S. attacks in recent weeks have left 50 people dead and more than 500 injured. In addition, 10,000 people remain without water due to attacks on a desalination plant in Hormozgan.

Washington has not acknowledged responsibility for the collapse of the pact. The Trump administration has defended the military operations as a response to Iranian actions against U.S. interests in the region and argues that the bombings are intended to reduce Iran’s military capabilities and protect strategic maritime routes, particularly around the Strait of Hormuz.

Today, the Great Satan has once again revealed its true, unmasked face, so that this dark episode of criminality and broken promises serves as yet another indisputable testament to the US’s dishonesty, irrationality, unreliability, and malicious nature.

The war that began in February

The current crisis erupted on February 28, when the United States and Israel launched a large-scale military offensive against Iranian targets, arguing that it was necessary to neutralize threats related to Tehran’s nuclear program and military capabilities. Iran responded with missile and drone attacks targeting U.S. bases and allied interests across several countries in the region, quickly turning the confrontation into an open war.

Over the following months, both sides exchanged bombardments while the international community sought to advance negotiations aimed at ending the hostilities. Those efforts resulted in a memorandum of understanding that allowed for a temporary reduction in fighting, although it never succeeded in fully eliminating distrust between the parties.

The definitive collapse of the agreement has once again raised international alarm. In recent hours, new attacks and military movements have already been reported across different parts of the Middle East, while the United States continues its air operations and Iran insists it will respond to any new offensive.

The deterioration of the situation is also increasing concern about the global economic impact. An intensification of the fighting could once again affect maritime traffic through the Strait of Hormuz, one of the world’s main routes for international oil trade, while also expanding the conflict to other countries where U.S. military bases are located.

For now, the chances of reviving negotiations appear increasingly slim. With the ceasefire officially broken, the exchange of threats between Washington and Tehran is fueling fears that the war between the two countries could enter an even more dangerous phase, with consequences that may extend far beyond Iran’s borders.
