Moments after President Trump tweeted that Iran and Israel agreed to a ceasefire, though neither country has confirmed this yet.

Vice President Vance told Fox News that Trump wants to work on a long-term settlement between the two countries.

Van says he thinks Iranians are at a place where they don't want to keep

on fighting. What the Iranians have showed through their support of terror networks, through their

now failed effort to build a nuclear weapon, is that they're just not very good at war. And I think

the president really hit the reset button and said, look, let's actually produce long-term peace

for the region.

This after Iran fired several missiles at a U.S. airbase in Qatar in retaliation for the U.S.

bombing three of Iran's nuclear sites over the weekend.

But Trump says the U.S. was warned in advance and there are no reports of casualties.

Meanwhile, another way Iran could retaliate

is by closing the Strait of Hormuz. The narrow waterway is a vital pathway for the world

energy supplies. And Piers Kat-Lonstorf has more. Around 20% of the world's oil and natural gas goes

through the Strait of Hormuz. A full closure, which has never happened before,

would have a major impact on energy markets around the world. Iran's parliament has voted to close

the straight according to Iranian state TV. The move would still require approval from Iran's top

security council. But closing it would also hurt Iran's economy, since its oil also passes through.

Energy experts tell NPR a more likely scenario would be Iran carrying out covert actions in the strait against certain ships

without completely halting trade. The price of crude oil has fluctuated in recent days,

and insurance for ships making the journey has gone up. Kat Lonsdorf, MPR News, Washington.
