President Donald Trump on Friday, April 10, issued a fresh warning to Iran as fragile ceasefire talks head into a critical weekend in Pakistan.

With negotiations scheduled to begin Saturday in Islamabad, Trump made clear that the United States expects Tehran to hand over its stockpile of enriched uranium and ensure the Strait of Hormuz stays fully open to international shipping.

Trump has informed the New York Post that if Iran does not make a deal in the next 24 hours, he is going to command the U.S. military to launch fresh strikes, this time around, using more advanced weapons as compared to the ones they were using before the ceasefire.

“And if we don’t have a deal, we will be using them, and we will be using them very effectively,” Trump said.

The remark came as U.S. officials voiced concern that the three-day-old ceasefire could fall apart before serious bargaining even starts.

On Friday, Iran’s Parliament Speaker Mohammad Baqer Qalibaf took to his X handle and suggested that peace talks should not proceed while disputes over the ceasefire terms linger, notably concerning Lebanon.

Qalibaf insisted that the agreement must cover Iran’s allies in the “resistance axis,” including a halt to Israeli strikes in Lebanon. He described ongoing violations as making bilateral talks unreasonable at this stage.

The approaching discussions in Islamabad will pit sharply opposing demands against each other. The U.S. side, led by Vice President JD Vance, Special Envoy Steve Witkoff, and Jared Kushner, is pressing for Iran to surrender its enriched uranium stockpile and guarantee unrestricted access through the Strait of Hormuz.

Trump vs Iran demands.

Trump has repeatedly stated there will be no uranium enrichment allowed under any final deal.

Tehran, by contrast, is insisting on immediate relief from U.S. sanctions, continued Iranian influence over the strait, and compensation for damage caused during the weeks of conflict.

Iranian officials have also pushed for the withdrawal of U.S. combat forces from bases across the region.

Iran also wants to charge ships for passing through the Strait of Hormuz and demand payment in Iranian rials.

The head of Iran’s Parliament National Security Commission announced the proposal, which would formalize transit fees for vessels using the narrow waterway.

The parliamentary committee has already approved elements of the wider Strait of Hormuz management plan, including financial arrangements and a rial-based toll system.

Trump asks Israel to go slow on Lebanon strikes.

On Thursday, April 9, President Trump directly urged Israeli Prime Minister Benjamin Netanyahu to ease operations in Lebanon.

Just as Iran had warned, Trump said Israel’s strikes on Iran-sponsored Hezbollah would jeopardize the talks.

The president told reporters he had instructed Netanyahu “to be sort of a little more low-key” to avoid derailing the talks.

U.S. officials worry that continued Israeli strikes could give Iran a reason to walk away from the table in Islamabad.

Netanyahu has signaled preparedness to adjust the pace of operations, though exchanges of fire with Hezbollah continued at a lower intensity into Friday.

Al-Jazeera reports that Hezbollah targeted Israeli military facilities on Friday using drones and missiles, which left at least 2 IDF soldiers seriously injured.

The ceasefire, brokered with Pakistani mediation and announced earlier this week, halted direct U.S. and Iranian hostilities for two weeks.

It followed Trump’s earlier deadline for Iran to reopen the strait or face renewed strikes. Iran restricted shipping through the vital chokepoint, which carries about one-fifth of global oil, causing energy prices to spike before agreeing to the pause.

Trump on Thursday criticized Iran for slow compliance on the Strait and reiterated that American forces will remain in the region to enforce any agreement.

Iranian leaders have accused the U.S. of allowing ceasefire breaches in Lebanon and blocking asset releases.

Vance, en route to Pakistan, warned Iran against attempting to “play” the United States during the negotiations.
