US-Iran ceasefire agreement expires amid accusations of violations
The June 17 memorandum between the United States and Iran ends on Monday, with both sides blaming each other for breaches and no clear indication of renewal.
The memorandum of understanding signed on June 17 by President Donald Trump and Iranian President Masoud Pezeshkian is set to expire on Monday, and neither side has indicated a willingness to extend it. Iran’s foreign minister, Abbas Araghchi, said on Telegram that Tehran has not decided to restart negotiations and is pursuing a separate arrangement with Oman on shipping routes in the Strait of Hormuz, contingent on a political solution.
U.S. officials have continued to press the issue. President Trump told supporters in New York that the United States would soon claim the strategic waterway, while Treasury Secretary Scott Bessent said new measures against Iran would be unprecedented.
The original agreement called for an immediate end to hostilities, a 60-day period for a final deal backed by the UN, the lifting of U.S. sanctions, the removal of a naval blockade, and a reconstruction package for Iran. Both parties have since accused each other of violating the terms. Trump described Iranian strikes as a “foolish violation,” and Iran claimed U.S. attacks breached Article 1 of the memorandum.
Analysts note that the United States faces limited military and economic options, with depleted interceptor missiles and strained strategic reserves. Iran, meanwhile, has reinforced its security leadership, appointing former IRGC chief Mohsen Rezaei to head the Supreme National Security Council, signaling a tougher stance in any future talks.
"The ceasefire stopped and was rendered obsolete after the US didn’t comply with the terms of the agreement, or the MoU," said Mostafa Khoshcheshm, a professor in Tehran.
"Iran is playing hardball here, clearly furious at the Trump administration for, in its view, not fulfilling the MoU signed back in June," said Barbara Slavin, a distinguished fellow at the Stimson Centre.
The expiration leaves the Gulf region in a state of uncertainty, with both sides maintaining control claims over the Strait of Hormuz and no immediate path to a renewed diplomatic framework.
