AP News in Brief at 6:04 a.m. EDT

The U.S. military said two American-flagged merchant ships had successfully transited the strait on Monday as part of a new initiative.

The UAE Defense Ministry said its air defenses had engaged 15 missiles and four drones fired by Iran. Authorities in the eastern emirate of Fujairah said one drone sparked a fire at a key oil facility, wounding three Indian nationals. The British military reported two cargo vessels ablaze off the UAE.

Tehran did not outright confirm or deny the attacks but early on Tuesday, Iran's Foreign Minister Abbas Araghchi said on X that both the U.S. and the UAE “should be wary of being dragged back into quagmire.”

In similarly vague terms, Iranian state television earlier quoted an anonymous military official as saying Tehran had had “no plan” to target the UAE or one of its oil fields.

What to know as the US tries to open the Strait of Hormuz and a ceasefire wavers

The ceasefire in the Iran war abruptly faced its most perilous moment Monday after the United States began trying to open the Strait of Hormuz to allow hundreds of stranded commercial ships sail out.

The United Arab Emirates said it came under attack for the first time since the early April ceasefire, and a British military monitor said two cargo vessels were ablaze off the UAE. There had been warning signs around the U.S. military-aided effort to guide ships through the strait, as Iran called it a violation of the fragile, three-week ceasefire.

Few ships had appeared to take advantage of “Project Freedom,” announced Sunday by President Donald Trump, though the U.S. said two U.S.-flagged merchant ships safely transited with its help.

Caution, even skepticism, is growing among shippers, and markets, over the lack of details from Washington. Who would risk their crew and cargo to possible Iranian fire?

Here’s what to know.

Trump's retribution? What to watch in Tuesday's elections in Indiana, Ohio and Michigan

President Donald Trump's campaign to politically punish Republicans who stand in his way moves through Indiana on Tuesday, when seven state senators face Trump-backed primary challengers.

In neighboring Ohio, primaries for U.S. Senate and governor will lock in the candidates for two major races with national implications.

And in Michigan, voters in a bellwether district will fill a vacancy in the state Senate, a race with implications for the balance of power in a battleground state.

Here's what to watch for.

Trump is taking aim at seven Republican state senators in Indiana who opposed his plan to redraw congressional district boundaries to help the party gain seats in the U.S. House.

Abortion pill rulings bring the issue back to the forefront in a midterm election year

NEW YORK (AP) — Back-to-back court rulings on abortion pill access are thrusting a contentious political issue back into the spotlight ahead of this year’s midterm elections that will determine control of Congress for the second half of President Donald Trump's term.

Friday’s ruling from a federal appeals court restricted mail access to mifepristone prescriptions, one of the most common abortion methods around the country, in the biggest shift to federal abortion policy since the Supreme Court’s 2022 decision allowing states to enforce abortion bans.

The Supreme Court then temporarily restored broad access to the drug on Monday while it further considers the case, setting the stage for a potential decision that could have wide-ranging consequences for patients and providers.

It’s too early to say whether the latest rulings will affect the outcome of races this year, when issues around affordability are expected to take top billing for voters. But advocates on both sides of the issue are hoping it will sway voters their way.

Some abortion rights groups already are strategizing ways to reach voters they think may be more motivated to turn out for Democrats because of the possibility of further restrictions. Meanwhile, abortion opponents who say the GOP-led federal government hasn’t done enough to ban the pills are warning their typically loyal Republican voters could sit out future elections, with a leading anti-abortion advocate calling it “a five-alarm crisis” for the GOP.

World shares mixed and oil prices retreat after the latest flare in Iran tensions

HONG KONG (AP) — World shares were mixed Tuesday, following losses on Wall Street after U.S. stocks retreated from record highs.

Oil prices fell back after rising earlier on escalating tensions in the war between the U.S. and Iran.

U.S. futures edged more than 0.2% higher.

In early European trading, Britain's FTSE 100 fell 0.8% to 10,280.87. France's CAC 40 was up 0.6% to 8,026.89, while Germany's DAX gained 1% to 24,232.45.

Asian regional trading was thin, with markets in Japan, South Korea and mainland China closed for holidays.

Armenia hosts a historic European Union summit as the country charts a course away from Russia

YEREVAN, Armenia (AP) — Armenia hosts its first bilateral summit with the European Union on Tuesday, a landmark diplomatic moment for the Caucasus Mountains nation that has formally declared its ambition to join the bloc and is cautiously loosening its ties with longtime ally Russia.

The EU-Armenia summit in Yerevan follows the eighth gathering of the European Political Community, or EPC, which brought dozens of European leaders to the Armenian capital on Monday to address European defense issues and the Iran war.

Meanwhile, Tuesday's bilateral meeting saw Armenia and the EU sign a connectivity partnership to strengthen economic ties and deepen security cooperation.

The two events underscore how Armenia is seeking to turn westward and shed Russia's influence. Armenia’s relations with Moscow, its longtime sponsor and ally, have grown increasingly strained since 2023, when neighboring Azerbaijan fully reclaimed the Karabakh region and ended the decadeslong rule by ethnic Armenian separatists.

Armenian authorities accused Russian peacekeepers who were deployed to the region of failing to stop Azerbaijan’s onslaught. Moscow, busy with the war in Ukraine, rejected the accusations, arguing that its troops didn’t have a mandate to intervene.

Restaurants celebrate authentic Mexican culture and history this Cinco de Mayo

Nayomie Mendoza has become accustomed to how Cinco de Mayo is celebrated in the U.S.: the platters of tacos, the pitchers of margaritas and the jubilant sounds of mariachi bands.

She is among a number of Mexican American business owners who've become more vocal about also honoring Mexican history and the significance of the holiday, as a way to combat anti-immigrant sentiments amid heightened immigration enforcement efforts that have targeted Latino communities.

Mendoza, owner of Cuernavaca’s Grill in Los Angeles, said she prefers a celebration that reflects “everything that as a community we’re enduring today.” So, Mendoza will host Cinco de Mayo festivities at her restaurant that, along with traditional mariachi and Mexican cuisine, will include a nod to Mexican perseverance over the French in the Battle of Puebla over 160 years ago.

“Just looking at how much they did with very little resources,” she said. “It just showed resilience. So, on Cinco de Mayo we always make it a testament of our resilience.”

Restaurants owners aren't the first Latino community leaders to reclaim Cinco de Mayo in the U.S. — moving away from a flattening of Mexican culture toward highlighting history and community. This year, the celebrations are noticeably embracing traditional Mexican culture and focused on preservation, said Sehila Mota Casper, director of Latinos in Heritage Conservation.

Tennessee Republicans will consider redrawing US House district covering majority-Black Memphis

NASHVILLE, Tenn. (AP) — As civil rights advocates protest, Republican lawmakers in several Southern states are seizing on the opportunity afforded by a U.S. Supreme Court ruling to redraw congressional districts ahead of the November midterm elections.

The latest state to jump on the redistricting bandwagon is Tennessee, where a special legislative session is to begin Tuesday, a day after a similar session kicked off in Alabama. In Louisiana, lawmakers are making plans for new U.S. House districts after the Supreme Court last week struck down the state's current map.

The high court’s ruling said Louisiana relied too heavily on race when creating a second Black-majority House district as it attempted to comply with the Voting Rights Act. The ruling significantly altered a decades-old understanding of the law and provided grounds for Republicans in various states to try to eliminate majority-Black districts that have elected Democrats.

Its impact on congressional representation, specifically for Black Americans, is threatening to undo decades of progress to ensure minority voting rights.

President Donald Trump has been encouraging more states to join in redistricting as Republicans seek to hold on to their narrow House majority in this year’s elections.

Vance gets a chance to woo Iowa GOP voters ahead of 2028 in a campaign stop with congressman

DES MOINES, Iowa (AP) — Vice President JD Vance will visit Iowa on Tuesday, marking his first visit since taking office to the state where Republicans in less than two years will cast the first votes to pick their party’s next presidential nominee.

Vance, who is seen as one of the GOP’s strongest potential candidates for president in 2028, is making the trip to campaign on behalf of Republican Rep. Zach Nunn, who faces a competitive race to keep his Des Moines-area seat in the November midterms.

But the visit offers Vance an opportunity to test his reception before Iowa’s voters, whose leadoff caucuses give them an outsized role in determining the next presidential nominee. Campaigning for a local congressman in his role as the sitting vice president gives him an opening chance to make an impression on Iowa Republicans, seasoned evaluators of those who seek the nation’s highest office before the campaign begins in earnest.

Vance’s appearance comes days after Texas Sen. Ted Cruz, who is also considered a possible 2028 candidate, spoke to a group of evangelical Christians who are influential in Iowa’s GOP contest.

Des Moines-based Jimmy Centers, a Republican political consultant, said the 2028 contest is “light-years away,” but said the Republicans who hear Vance speak on Tuesday will be evaluating how he might measure up in an election for the White House.
