Welcome to the NewsHour. President Trump announced late today that the ceasefire between Israel and Lebanon will be extended by three weeks.

That ceasefire covers fighting between Israel and Hezbollah, the Iran-backed militant group based in Lebanon.

Separately, Mr. Trump told reporters earlier he was in no rush to reach a deal with Iran after his latest ceasefire extension.

Just two days after President Trump extended his two-week ceasefire with Iran, the prospect of

The Vessel, Majestic X, we intend to conduct the boarding of your vessel.

The Pentagon released its own footage of U.S. forces on the deck of an oil tanker today in the

Indian Ocean, a ship accused of smuggling Iranian oil, and President Trump posted to social media that he had ordered the United States

Navy to shoot and kill any boat that threatens the strait by laying underwater mines or otherwise

without hesitation. Speaking to reporters today, the president said he's in no rush to set a deadline

on his latest ceasefire extension.

He said that was to allow Iran time to sort out what he characterized as its fractured leadership.

They're not doing well economically, financially.

They're not doing any business because of the blockade.

They want to make a deal.

We have been speaking to them,

but they don't even know who's leading the country. They're in turmoil. They're in turmoil. So we thought

we'd give them a little chance to get some of their turmoil resolved. When asked, the president also

backed off any threat to use a nuclear weapon against Iran.
