The United States and Iran have reached a deal to end the war that began earlier this year [1].

The agreement aims to establish an immediate and permanent halt to military operations. This resolution is critical for restoring stability to a region that has faced escalating violence following the initial strikes in February [2].

President Donald Trump said the deal was reached Sunday, June 16 [3]. The conflict was sparked by joint American and Israeli strikes on Iran on Feb. 28, 2026 [1]. Those strikes triggered a period of hostilities that have now led to this diplomatic breakthrough.

According to officials, a formal signing ceremony is scheduled for June 19, 2026 [4]. The event will take place in Switzerland, serving as neutral ground for the two nations to finalize the terms of the peace agreement [5].

World leaders have reacted with relief to the news. Pakistani Prime Minister Shehbaz Sharif said he welcomed the move toward regional security [6]. Other international leaders have praised the agreement as a necessary step to prevent further escalation in the Middle East.

The deal focuses on bringing a permanent end to the war and ensuring that military operations do not resume. While some reports suggest the peace is already in effect, the upcoming ceremony in Switzerland is intended to formalize the legal, and diplomatic, framework of the ceasefire [4], [7].

This diplomatic shift follows months of tension and military engagement. The transition from active conflict to a signed treaty represents a significant pivot in U.S. foreign policy toward Tehran.

The United States and Iran have reached a deal to end the war.

The agreement signals a rapid shift from military escalation to diplomacy, following the February 28 strikes.
