Tehran put limits on the Strait of Hormuz’s opening, as the United States issued a new sanctions exemption on the sale of Russian oil.

Even amid uncertainty over whether the truce would hold, many in Lebanon expressed relief at the prospect of quiet as aid groups mobilized help.

Iran has not confirmed Trump’s claim. Giving up its highly enriched uranium would be a major step toward an agreement.

President Donald Trump announced the agreement, which went into force Thursday evening, as Pakistani mediators worked to extend a U.S.-Iran ceasefire and arrange new talks.

Peace talks broke down over Iran’s nuclear program, which has survived two decades of international diplomacy seeking to curtail it and more than five weeks of bombing.

The blockade could derail a tenuous ceasefire after just five days. Vice President JD Vance said the U.S. remains open to diplomacy if Iran takes “our final and best offer.”

Vice President JD Vance was leading the highest level of face-to-face engagement between leaders of the United States and Iran in decades.

Amid allegations of bad faith and ceasefire violations from both Washington and Tehran, negotiators arrived in Islamabad for high-stakes talks.

The sides are far apart on Iran’s nuclear program, the Strait of Hormuz and the Israeli campaign against Hezbollah in Lebanon.

Iran accused the U.S. and Israel of violating the truce and threatened to withdraw from negotiations. Israeli attacks in Lebanon were a major point of dispute.

People in Iran say they could be left to pick up the pieces if President Donald Trump destroys the country’s infrastructure and economy.

The president says Iran’s remaining leaders are more reasonable. But assassinations have left in place an emboldened government driving a hard bargain, officials say.
