President Donald Trump announced Wednesday that the ceasefire and interim agreement to end the war with Iran are now over [2].

The decision signals a sharp escalation in tensions between the two nations, potentially reigniting a full-scale military conflict in the Middle East.

Trump made the announcement during the NATO Summit 2026 in Ankara, Turkey [2, 3]. He said that negotiations had been a waste of time and that ongoing tit-for-tat strikes had rendered the agreement untenable [1, 4].

During the press conference, Trump used harsh language to describe the Iranian leadership, calling them "scum" [1]. He said that the U.S. would resume aggressive military operations immediately, stating, "We're going to hit them hard again tonight" [4].

Global markets reacted to the news of the collapsed diplomacy. Oil prices rose five percent following the announcement [4].

While some reports from Yahoo Finance suggested the U.S. was extending the ceasefire, the president's direct statements in Ankara contradict those claims [1, 2]. The move comes as NATO allies gather in Turkey to discuss regional security, and the stability of the Gulf region.

Trump said the previous attempts at a diplomatic resolution failed to prevent continued hostilities. He said that the U.S. would no longer pursue the interim framework that had previously limited strikes against Iranian targets [4].

"The ceasefire and interim agreement to end the war with Iran are now 'over'."

The collapse of the interim agreement removes the primary diplomatic barrier preventing open warfare between the U.S. and Iran. By announcing this at a NATO summit, the U.S. is likely seeking coordinated support or strategic alignment from its allies before initiating new strikes, while the immediate spike in oil prices reflects global economic anxiety over the security of the Strait of Hormuz.
