Welcome to the NewsHour.

Vice President JD Vance is heading to Pakistan where he's set to meet Iranian officials this weekend in a bid to end the nearly six-w week USIsrael war with Iran.

The demands are steep, trust is thin, and President Trump said today he's unsure if he'll support further talks after this round.

Meanwhile, in Lebanon, residents are still digging out from this week's Israeli strikes.

Liz Landers starts our coverage.

Today in Lebanon, pain and grief as mourners gathered to share memories and bid a final farewell to loved ones following Israel's deadliest wave of strikes since the start of war.

Devastating buildings and leaving more than 300 dead.

The loss of people can never be replaced, you know.

But as for the stones and buildings, God can compensate for that.

What can we do?

We want to live, not continue in this situation.

It's compounding an already desperate humanitarian situation.

According to the World Food Program, the conflict has displaced over 1 million people.

And even before the Iran war, more than 800,000 people in Lebanon faced acute food insecurity, causing aid teams to scramble on the ground and provide food to families like this one.

That suffering is dividing Lebanon's people on the merits of planned peace talks with Israel next week.

Negotiation is the only way to peace and for people to live.

People are all displaced living on the streets.

People aren't living.

If you want to conduct negotiations under war as Israel wants to operate under fire, we do not accept and we will remain steadfast.

Meanwhile, in Israel, sirens blared after Iranbacked Hezbollah fired a barrage of missiles, one of which damaged this church complex.

The IDF says it struck 10 Hezbollah launchers inside Lebanon.

But before the Israel Lebanon talks, another major test of diplomacy.

US and Iranian officials are gearing up for highstakes negotiations this weekend aimed at making a ceasefire permanent.

Earlier this week, President Trump escalated his rhetoric with a startling threat to wipe out Iran civilization, but he quickly reversed course after a shaky two-week truce was reached.

The president relayed his expectations to reporters this afternoon.

What would a good deal look like for you?

Um, no nuclear weapon, number one.

You know, I think it's already been regime change, but we never had that as a as a criteria.

No nuclear weapon.

The talks to be held in Pakistan are the most senior level negotiations between the US and Iran since the Islamic Revolution in 1979.

The US is sending members of Trump's innermost circle, special envoy Steve Whit and the president's son-in-law Jared Kushner.

We're looking forward to the negotiation.

And Vice President JD Vance, who gave the Iranians a warning as he boarded his plane to Islamabad early today.

If the Iranians are willing to negotiate in good faith, we're certainly willing to extend the open hand.

If they're going to try to play us, then they're going to find that the negotiating team is not that receptive.

Leading the Iranian side, the speaker of Iran's parliament, Muhammad Ber Galibah.

He warned tomorrow's negotiations could be called off unless two outstanding agreements from the temporary truce are implemented.

A ceasefire in Lebanon and the release of Iran's blocked assets.

Those conditions were echoed by Iran's revolutionary guard corps and the foreign ministry.

Meanwhile, the US has made demands of its own, namely for Iran to end its blockade of the Straight of Hormuz as agreed upon.

Marine traffic data from today shows hundreds of vessels crowding the Gulf.

Yet only a handful selected by Iran trickling through the narrow but critical maritime passageway.

On Truth Social today, President Trump said Iran has quote no cards other than a short-term extortion of the world by using international waterways.

And last night, he acknowledged reports that Iran is charging tankers to pass through $2 million in Bitcoin per ship, as Iran has publicly claimed.

Quote, "They better not be," the president wrote.

And if they are, they better stop now.

Iran, meanwhile, doubled down.

The street of Hormuz will not return to the pre-war control system.

All movements, traffic, comingings and goings in the street of Hormuz are under strict, precise, and calculated control of our armed forces.

Meanwhile, the world is watching.

Today, Pope Leo warning that quote, "God does not bless any conflict."

Instead, urging parties towards dialogue to reach peace.
