Iran has formally submitted a complaint to the United Nations Security Council over what it described as U.S. violations of a landmark ceasefire agreement. In an official letter, Tehran accused Washington of repeatedly breaching the Islamabad Memorandum and called for immediate international action.
Iran’s Permanent Representative to the United Nations, Amir Saeid Iravani, rejected U.S. claims of self-defense and accused Washington of acting as the aggressor in the conflict. The dispute centers on a June agreement mediated by Pakistan that aimed to end months of hostilities. The accord called for a permanent ceasefire and the reopening of the Strait of Hormuz.
Tehran claimed that Washington began violating the agreement shortly after its signing. Iranian officials listed 42 alleged breaches, including military attacks against Iran’s sovereignty and territorial integrity. They also accused the United States of revoking oil export licenses and interfering with maritime transit arrangements.
According to Iran, paragraph five of the agreement gives Tehran responsibility for securing the strategic waterway. Iranian officials objected to U.S. efforts to create an alternative maritime route under Western military protection. They argued that such actions have increased regional insecurity and disrupted international shipping. Tehran also criticized Washington for failing to stop Israeli military operations in Lebanon.
The Iranian report outlined alleged violations that occurred between mid-June and mid-July. Meanwhile, U.S. President Donald Trump announced plans to restore a naval blockade against Iran and suggested that Washington could impose transit fees on ships using the route. Iranian officials criticized the Security Council for not taking stronger action in response to the escalating tensions.
The Security Council recently extended a mandate related to reports on separate attacks in the Red Sea. China and Russia abstained from that vote, citing concerns over rising regional tensions. Beijing previously supported the agreement and urged all parties to preserve diplomatic efforts. The dispute over the Islamabad Memorandum has further increased tensions across the Persian Gulf, raising concerns about regional stability and international maritime security.
