This is the PM edition of What's News, the top headlines and business stories that move the world today.

This morning, the U.S.

sank an Iranian ship in the Indian Ocean, killing at least 87 people.

Defense Secretary Pete Hegseth said it was the first time a U.S.

torpedo had sunk an enemy ship since World War II.

Washington is determined to destroy Tehran's navy and safeguard the flow of oil through the Persian Gulf.

In a news conference at the Pentagon, Hegseth provided a new timeline for the duration of the war.

The conflict risks drawing in NATO allies.

Today, the U.S.

also shot down an Iranian missile headed to a Turkish military base that hosts American forces.

Iran had refrained from attacking Turkey until now.

And in recent days, the U.K.

and France have said that they would send additional warships to the region after an Iranian drone targeted a British military base in Cyprus.

Meanwhile, on Capitol Hill, the Senate is voting today on a resolution over Trump's war powers.

The push to stop the military operation against Iran is expected to fail as most Republicans back the president.

Senator Tim Kaine, a Democrat from Virginia who sponsored the resolution, spoke from the Senate floor ahead of the vote.

Senator Mitch McConnell of Kentucky defended the president's decision to strike Iran and said presidential power to use military force without congressional approval was, quote, well-established.

But he warned in a floor speech that there are risks involved and that Trump needs to explain his strategy to the American public.

A vote on a similar measure in the House is expected tomorrow.

As we've been covering on the show this week, the conflict in the Middle East has thrown the global oil market for a loop.
