The United Nations World Food Program said Tuesday that an aid worker has died in a Yemeni prison three weeks after his detention by Houthi rebels.

The announcement came a day after the U.N. suspended its operations in the rebel's stronghold in northern Yemen.

President Donald Trump is hitting foreign steel and aluminum with a 25% tax. If that sounds familiar, it's because he did pretty much the same thing during his first term.

Trump's original metals tariffs gave America's struggling steel and aluminum producers some relief from intense global competition, allowing them to charge higher prices. In anticipation of the new tariffs, shares of steel and aluminum producers climbed Monday. Nucor rose 5.6%, Cleveland-Cliffs jumped 17.9% and Alcoa ticked up 2.2%.

U.S. tariffs on steel and aluminum "will not go unanswered," European Union chief Ursula von der Leyen vowed on Tuesday, adding that they will trigger tough countermeasures from the 27-nation bloc. It means iconic U.S. industries like bourbon, jeans and motorcycles should beware.

"The EU will act to safeguard its economic interests," von der Leyen said in a statement in reaction to U.S. President Donald Trump's imposition of tariffs on steel and aluminum the previous day.

Nearly 200 nations faced a Monday deadline to file what the United Nations' climate chief calls "among the most important policy documents governments will produce this century" — their plans on how they will cut emissions of heat-trapping gases.

Most won't make the deadline. The U.N. says that's OK as long as they are working on them.

U.S. Vice President JD Vance on Tuesday warned global leaders and tech industry executives that "excessive regulation" could cripple the rapidly growing artificial intelligence industry in a rebuke to European efforts to curb AI's risks.

The speech underscored a widening, three-way rift over AI.

Ukraine has offered to strike a deal with U.S. President Donald Trump for continued American military aid in exchange for developing Ukraine's mineral industry, which could provide a valuable source of the rare earth elements that are essential for many kinds of technology.

Trump said that he wanted such a deal earlier this month, and it was initially proposed last fall by Ukrainian President Volodymyr Zelensky as part of his plan to strengthen Kyiv's hand in future negotiations with Moscow.

Atop a skyscraper, Wes Gordon unveiled his latest Carolina Herrera collection to an eager crowd at New York Fashion Week.

Models strutted down the runway adorned with 3,000 burgundy wine-colored ranunculus flowers while Gordon's "personal assortment of songs" played in the background, including Fleetwood Mac's, "Dreams." The backdrop was a gorgeous, 360-degree view of blue sky and New York City delivered by floor-to-ceiling windows on the 48th floor.

Israeli police raided a long-established Palestinian-owned bookstore in east Jerusalem, detaining the owners and confiscating books about the decades-long conflict. The police claimed the books incited violence.

The Educational Bookshop, established over 40 years ago, is a hub of intellectual life in east Jerusalem, which Israel captured in the 1967 Mideast war and annexed to its capital in a move not recognized internationally. Most of the city's Palestinian population lives in east Jerusalem, and the Palestinians want it to be the capital of their future state.

President Donald Trump will host Jordan's King Abdullah II at the White House on Tuesday as he escalates pressure on the Arab nation to take in refugees from Gaza — perhaps permanently — as part of his audacious plan to remake the Middle East.

The visit is happening at a perilous moment for the ongoing ceasefire in Gaza as Hamas, accusing Israel of violating the truce, has said it is pausing future releases of hostages and as Trump has called for Israel to resume fighting if all those remaining in captivity are not freed by this weekend.

All architecture student Amirhossein Azizi wanted for his 19th birthday was the latest iPhone — and for Iran's cash-strapped theocracy, it was just the gift they needed as well.

Just buying a top-of-the-line iPhone 16 Pro Max in Iran's capital cost him on the day 1.6 billion rials ($1,880). An additional 450 million rials ($530) is required for import fees and registration on government-managed mobile phone networks.
