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

The news threw into question President Donald Trump 's earlier announcement that U.S. negotiators would head to Pakistan on Monday for another round of talks with Iran. A fragile ceasefire is set to expire by Wednesday, and Washington and Tehran remain in a standoff over the strait.

Trump on social media said a U.S. Navy guided missile destroyer in the Gulf of Oman warned the ship, the Touska, to stop and then “stopped them right in their tracks by blowing a hole in the engineroom." U.S. Marines had custody of the U.S.-sanctioned vessel and were “seeing what’s on board!”

There was no immediate Iran comment. The U.S. Central Command said the destroyer had issued “repeated warnings over a six-hour period.”

There was no comment from Iranian officials on Trump's announcement of the talks.

8 children between the ages of 1 and 14 are dead after a mass shooting in Louisiana, police say

SHREVEPORT, La. (AP) — A gunman in Louisiana killed eight children and shot two other people Sunday in an early morning attack of domestic violence carried out across two houses, authorities said, shaking a Shreveport neighborhood in one of the nation’s deadliest mass shootings in more than two years.

The suspect died after a police pursuit, and the victims — who ranged in age from 1 to about 14 years old — included children related to the gunman, said Shreveport Police Department spokesperson Chris Bordelon. Investigators did not say what may have set off the attack.

“This is an extensive scene unlike anything most of us have ever seen,” Bordelon said.

Officers fired at the suspect during a chase after he carjacked a vehicle at gunpoint, Bordelon said.

Police said the attacks began before sunrise in a neighborhood south of downtown Shreveport when the suspect shot a woman at one home and then drove to the other location “where this heinous act was carried out.”

Businesses can claim refunds for Trump tariffs ruled unconstitutional starting Monday

NEW YORK (AP) — A refund system for businesses that paid tariffs which the U.S. Supreme Court ruled President Donald Trump imposed without the constitutional authority to do so is scheduled to launch Monday.

Importers and their brokers will be able to begin claiming refunds through an online portal beginning at 8 a.m., according to U.S. Customs and Border Protection, the agency administering the system.

It's the first step in a complicated process that also might eventually lead to refunds for consumers who were billed for some or all of the tariffs on products shipped to them from outside the United States.

Companies must submit declarations listing the goods on which they collectively put billions of dollars toward the import taxes the court subsequently struck down. If CBP approves a claim, it will take 60-90 days for a refund to be issued, the agency said.

The government expects to process refunds in phases, however, focusing first on more recent tariff payments. Any number of technical factors and procedural issues could delay an importer's application, so any reimbursements businesses plan to make to customers likely would trickled down slowly.

The center-left coalition of former President Radev will win Bulgaria's election, exit poll suggests

SOFIA, Bulgaria (AP) — A center-left coalition led by Bulgaria ’s former President Rumen Radev will win the parliamentary election, an exit poll suggested hours after polls closed on Sunday. The list is unlikely to garner enough votes to rule alone, which could prolong a yearslong political deadlock in the European Union country.

The election on Sunday was the country's eighth in five years, illustrating a crippling political impasse that has gripped this Balkan nation. Preliminary results are expected on Monday.

The poll conducted by Trend research group showed Radev's Progressive Bulgaria earning 39.2% support, edging out the center-right GERB party of its veteran leader, Boyko Borissov, which is expected to capture 15.1% of the vote. Despite the huge gap between the two groups, the predicted percentage may not be enough for Radev to form a one-party government, and he will face the uphill task of looking for partners to govern.

The exit poll also predicted that voter turnout stood at 43.4%, and that six parties could pass the 4% threshold to enter a fragmented parliament.

Radev said after the initial projections were announced that “we will do our best to prevent having to go to the polls” again.

Wisconsin authorities put total arrests from clashes at beagle breeding facility at about 25

MADISON, Wis. (AP) — Around 25 protesters were arrested as around 1,000 animal welfare activists tried to gain entry to a beagle breeding and research facility in Wisconsin and were met by officers firing pepper spray and rubber bullets, authorities said Sunday.

Saturday's protest was the second attempt in as many months by demonstrators to take beagles from Ridglan Farms in Blue Mounds, about 25 miles (about 40 kilometers) southwest of the capital, Madison. They were turned back by officers who arrested the group’s leader.

The Dane County Sheriff's Office said the situation was “significantly calmer and more peaceful” on Sunday, when around 200 people assembled outside the farm. They dispersed after around two hours, it said.

“We’re pleased with the group’s cooperation today, and their willingness to remain peaceful, while still sending their message of concern for the dogs at Ridglan Farms,” Sheriff Kalvin Barrett said in a statement. “We are happy to support anyone who wants to exercise the right to protest, as long as they do so lawfully.”

The sheriff had said in a video statement Saturday that 300 to 400 protesters were “violently trying to break into the property.” They tried to overcome barricades that included a manure-filled trench, hay bales and a barbed-wire fence.

Los Angeles woman arrested on Iranian arms trafficking charge

LOS ANGELES (AP) — Federal prosecutors said a 44-year-old Los Angeles woman was arrested Saturday night at Los Angeles International Airport on suspicion of helping Iran traffic weapons to Sudan, which is in its fourth year of a bloody civil war.

Shamim Mafi will face charges that she brokered the sale of “drones, bombs, bomb fuses, and millions of rounds of ammunition” between Iran and the Sudanese Armed Forces, First U.S. Attorney Bill Essayli said Sunday on social media.

A phone number for Mafi could not be located and it wasn't known Sunday if she has an attorney who could speak on her behalf.

Essayli posted a photo of someone in an FBI jacket escorting a woman into the back of a sedan outside a terminal at LAX.

Mafi is an Iranian national who became a lawful permanent resident of the United States in 2016, Essayli said.

Fears of looser standards as the FBI and Justice Department scramble to fill a depleted workforce

WASHINGTON (AP) — The FBI and Justice Department are scrambling to rebuild a depleted workforce after a wave of departures over the past year, with leaders easing hiring requirements and accelerating recruitment in ways that some current and former officials see as a lowering of long-accepted standards.

The FBI has used social media campaigns to attract applicants, offered abbreviated training for candidates from other federal agencies and relaxed requirements for support staff seeking to become agents, according to people familiar with the changes and internal communications seen by The Associated Press. At the same time, the Justice Department has opened the door to hiring prosecutors right out of law school to help fill vacancies in U.S. attorney’s offices across the country.

Some current and former agents also say the FBI is promoting into positions of leadership employees with less experience than would be customary for the jobs.

The moves reflect a broader effort to stabilize a workforce strained by retirements and resignations prompted in part by concerns over the Trump administration's politicization of the department, along with the firings of lawyers, agents and other employees deemed insufficiently loyal to the Republican president's agenda. Critics of the changes say they amount to a reduction in standards for a law enforcement institution that has long prided itself on professional expertise and is responsible for everything from preventing terrorist attacks to building complex public corruption prosecutions.

“It’s a sign of, among other things, the difficulty the department is having right now in keeping and recruiting people,” said Greg Brower, a former U.S. attorney in Nevada who left the FBI in 2018 as its chief congressional liaison.

Trump wants to stop states from regulating AI. This Utah Republican isn't listening

RIVERTON, Utah (AP) — When a dozen Republican activists gathered on a back deck in the Salt Lake City suburbs to talk about this year's elections, the conversation cycled through all the staples of conservative chatter in Utah such as dwindling water supplies, illegal immigrant fraud and chemtrail conspiracy theories.

But Doug Fiefia, a state representative running to be a state senator, wanted to start with something else — artificial intelligence. Fiefia used to work at Google and, like several other tech employees who have gone into politics, he has made regulating the industry a centerpiece of his campaign.

“I know it sounds like ‘Doug, this is all you talk about,”’ Fiefia said. “That’s because it’s coming, it’s here and it’s going to be our biggest fight.”

Fiefia's focus has put him on a collision course with President Donald Trump's administration, which this year helped block his state proposal requiring companies to include child safety protocols. The White House wants a single national standard for artificial intelligence, arguing that a patchwork of excessive regulation could handicap American innovation in a global competition with China.

But with no progress in Congress, it has been state lawmakers struggling to address concerns about a technology that is poised to reshape the economy. In Florida, Republican Gov. Ron DeSantis added the issue to a special legislative session that he is convening later this month. Democratic-controlled New York last year required major AI developers to report dangerous incidents to the state.

Pope prays at Catholic shrine in Angola that was a center of African slave trade

MUXIMA, Angola (AP) — Pope Leo XIV on Sunday recalled the “sorrow and great suffering” Angolans endured for centuries, as the American pope prayed at a Catholic shrine located at the site of an important hub of the African slave trade during Portugal's colonial rule.

Leo traveled to the Sanctuary of Mama Muxima, nestled in the Angolan savanas of baobab trees at the edge of the Kwanza River. It became a major pilgrimage destination after believers reported an appearance by the Virgin Mary around 1833.

But the Church of Our Lady of Muxima was originally built by Portuguese colonizers at the end of the 16th century as part of a fortress complex and it became a hub in the slave trade. It was where enslaved Africans were gathered to be baptized by Portuguese priests before being forced to walk to the port of Luanda, over 110 kilometers (70 miles) to the north, to be put on ships to the Americas.

Leo, whose own ancestors include enslaved people and slave owners, prayed the Rosary at the sanctuary, a simple whitewashed church with blue trim and a statue of the Madonna inside. Speaking in Portuguese, he recalled it was here “where, for centuries, many men and women have prayed in times of joy and also in moments of sorrow and great suffering in the history of this country.”

He didn’t refer specifically to slavery. After viewing plans to build a basilica at the site, Leo urged the estimated 30,000 people gathered outside to also build “a better, more welcoming world, where there are no more wars, no injustices, no poverty, no dishonesty."

Eddie Murphy receives life achievement award by AFI, drawing standing ovation at star-filled tribute

LOS ANGELES (AP) — Eddie Murphy took a moment to look out at the star-studded room at the American Film Institute ceremony — at his family, his peers, the people who have shared his journey — and let it all sink in.

“Seeing all of my family, all my kids, my beautiful wife, and seeing all the different people I worked with, I’m just really filled up,” said Murphy, who received the life achievement award at the Dolby Theatre in Los Angeles on Saturday night. “This is a special moment. I wish y’all could feel what I’m feeling, see what I’m seeing. I almost teared up. I’m going to get backstage and cry.”

Just before accepting the award, Murphy was met with a standing ovation, stepping onstage and moving through the ballroom as the applause followed. Along the way, he passed Spike Lee, Martin Lawrence, Dave Chappelle, Chris Rock, Arsenio Hall and Judge Reinhold.

The tribute, which also featured appearances from Bill Burr, Kevin Hart, Eva Longoria, Da'Vine Joy Randolph and Kenan Thompson, will premiere as a special on Netflix on May 31.

Murphy, 65, has moved from a teenage stand-up sensation to a breakout force on “Saturday Night Live” to a box office mainstay with films like “Beverly Hills Cop,” “Coming to America,” “The Nutty Professor” and the “Shrek” franchise.
