On the same day the U.S.

struck an Iran tanker, the Senate gathered to debate reining in President Trump's war powers and bringing the conflict to a halt.

A few Republicans expressed some reservations, but a measure brought to the floor ultimately failed.

The vote fell almost completely along party lines, allowing Trump to continue military action without the need for congressional approval.

Democrat Senator Tim Kaine authored the resolution.

But Republican Majority Leader John Thune told Fox News the president had his party's support.

In the opening days of the conflict, a big part of Iran's response has been to strike out at neighboring countries.

That's taken many Americans staying there by surprise, with thousands now desperately trying to get out, something we wanted to spend a few minutes looking at today.

On Monday, the U.S.

State Department posted a warning on social media telling its citizens to leave immediately.

But that's much easier tweeted than done.

It's terrifying.

I mean, we're not used to it in the US where you just hear fighter jets going on all day long and you certainly don't hear the missiles actually landing and blowing up.

We are finally evacuating Kuwait on our own terms by land.

Nearly 3,000 Americans have asked the State Department for assistance, and a state official told CBS that they believed over a million U.S.

nationals were in the region.

Initially, people were advised to find their own way out via commercial routes, but then Iranian bombs began flying towards airports in the Gulf, which led to airspace closures, making a quick exit all but impossible.

Five days into the war, Dubai's airport, the world's busiest hub for international travelers, remains mostly closed to commercial flights.

Also, several key embassies have been forced shut by bombings.

According to reports, calls to the State Department hotline were met with a prerecorded message that said no help was available, and multiple embassies issued a notice warning they were in no position to assist evacuations.
