The United States carried out a new round of strikes on Iran on Tuesday, and President Trump declared that the ceasefire agreed in June was finished, a sharp escalation in a conflict that had been paused for weeks. Trump made the announcement while attending a NATO summit in Ankara.

Trump calls the truce over

Speaking to reporters at the summit, Trump said the memorandum of understanding reached with Iran in June was "over," while suggesting negotiators might still try to talk, Al Jazeera reported. That agreement had halted fighting for about two months while the two sides discussed Iran's nuclear program and sanctions, and it had been meant to keep shipping moving freely through the Strait of Hormuz.

What the US says it struck

US Central Command said its forces had "started conducting additional strikes against Iran to further degrade their ability to threaten freedom of navigation in the Strait of Hormuz," Al Jazeera reported. The command did not immediately give a full list of targets. Iranian media reported explosions in southern Iran and said air defenses had been activated. Newsparlor could not independently confirm what was hit, and there was no verified account of casualties.

How it got here

The renewed strikes followed attacks earlier in the week on commercial ships in the Strait of Hormuz, including the tankers Al Rekayyat and Wedyan, which the United States and Gulf governments blamed on Iran. Washington said its response was aimed at protecting the waterway, through which a large share of the world's oil passes. Iran, which had told vessels to keep to a designated route near its coast, has cast the US strikes as violations of the truce.

What it means

The exchange marks another turn in a conflict that has lurched between escalation and pause since the spring, repeatedly unsettling oil markets and the wider region. Trump's declaration that the ceasefire is "over" removes, at least rhetorically, the framework that had contained the fighting, even as he left the door open to further talks. Much remains unclear tonight, including the scale of the latest strikes and any casualties, and the situation is developing. What is clear is that the pause that had held since June has, for now, broken down.
