Iran and the United States have signed a ceasefire and diplomatic agreement on June 11, 2026, ending weeks of direct military conflict that erupted in May 2026 — the first open war between the two nations in modern history.
Background: The May 2026 War
Hostilities broke out in early May 2026 after the United States, alongside Israel, launched a series of airstrikes targeting Iran’s nuclear facilities at Fordow, Natanz, and Isfahan. Iran retaliated with ballistic missile strikes on US bases in Qatar and Iraq and launched drone attacks against Israeli territory. The conflict lasted approximately 22 days before international pressure — led by China, Russia, and the UN Security Council — forced both parties to the table.
The June 11 Agreement: Key Terms
- Immediate ceasefire: All military operations ceased effective 00:01 GMT on June 11, 2026.
- Nuclear programme suspension: Iran agreed to a full suspension of uranium enrichment for a minimum of 5 years, with IAEA inspectors granted unrestricted access to all sites.
- US sanctions lifted: Washington agreed to lift all secondary sanctions on Iranian oil, banking, and trade within 45 days of the agreement taking effect.
- Prisoner exchange: Both nations agreed to release all military and civilian detainees captured during the conflict within 15 days.
- No regime change clause: The US formally pledged not to pursue or support any effort to change Iran’s government — a key Iranian demand.
- Reconstruction fund: A joint international fund of $10 billion, co-sponsored by the EU and Gulf states, will support reconstruction of damaged Iranian civilian infrastructure.
Signing Ceremony
The agreement was signed in Geneva, Switzerland on June 11, 2026, witnessed by UN Secretary-General António Guterres. US Secretary of State Marco Rubio and Iranian Foreign Minister Abbas Araghchi signed on behalf of their respective governments.
Global Reaction
World leaders broadly welcomed the deal. Pakistan’s Foreign Office issued a statement calling it “a relief for regional stability,” while Saudi Arabia and the UAE expressed cautious optimism. Israel’s Prime Minister Benjamin Netanyahu acknowledged the ceasefire but said Israel “reserves the right to act independently” if Iran resumes nuclear activity. Oil prices fell over 6% on the news, with Brent crude dropping to $74 per barrel.
What Comes Next
A follow-up diplomatic summit is scheduled for July 20, 2026 in Geneva to begin negotiating a permanent nuclear treaty. The US Senate and Iran’s Supreme National Security Council must both ratify the current agreement within 30 days for it to take full legal effect. Analysts say the deal, while fragile, represents the most significant shift in US-Iran relations since the 1979 Islamic Revolution.
