President Donald Trump on Thursday threatened sanctions on anyone who buys Iranian oil, a warning that came after planned talks over Tehran’s rapidly advancing nuclear program were postponed.

Trump wrote on social media, “All purchases of Iranian Oil, or Petrochemical products, must stop, NOW!” He said any country or person who buys those products from Iran will not be able to do business with the United States “in any way, shape, or form.”

It was unclear how Trump would implement such a ban as he threatened to levy secondary sanctions on nations that import Iranian oil. But his statement risked further escalating tensions with China — Iran’s leading customer — at a time when the relationship is severely strained over the U.S. president’s tariffs.

Based on tanker tracking data, the U.S. Energy Information Administration concluded in a report published last October that “China took nearly 90% of Iran’s crude oil and condensate exports in 2023.” Trump has separately placed 145% tariffs on China as a way to raise federal revenues and rebalance global trade.

Trump’s social media threat came after Oman announced planned nuclear negotiations for this coming weekend had been postponed. Omani Foreign Minister Badr al-Busaidi made the announcement in a post on the social platform X.

“For logistical reasons we are rescheduling the US Iran meeting provisionally planned for Saturday May 3rd,” he wrote. “New dates will be announced when mutually agreed.”

Pentagon adding second border military zone

The Pentagon is creating a second expanded military zone at the Mexican border, to be patrolled by U.S. soldiers, in the Trump administration’s latest step to militarize the boundary with Mexico to help stem the flow of migrants.

The military’s Northern Command said in a statement Thursday evening that it was establishing a narrow strip of land along the southern border of Texas that will become part of Fort Bliss, near El Paso. The strip will be about 63 miles long.

Last month, the Pentagon created a 60-foot-wide strip of land along 200 miles of the border between New Mexico and Mexico, effectively turning it into part of a U.S. military base there.

Migrants entering the newly designated military installations, or national defense areas, will be considered to be trespassing and can be temporarily detained by U.S. troops until Border Patrol agents arrive, military officials said.

A small group of migrants was charged Monday with crossing into the military zone in New Mexico after an Army helicopter spotted them approaching the border and alerted the Border Patrol.

Homeless cleared from federal forest in Oregon

Dozens of homeless people who have been living in a national forest in central Oregon for years were being evicted Thursday by the U.S. Forest Service, as it closed the area for a wildfire prevention project that will involve removing smaller trees, clearing debris and setting controlled burns over thousands of acres.

The project has been on the books for years, and the decision to remove the encampment in the Deschutes National Forest comes two months after the Trump administration issued an executive order directing federal agencies to increase timber production and forest management projects aimed at reducing wildfire risk.

Deschutes National Forest spokesperson Kaitlyn Webb said in an email that the closure order was “directly tied to the forest restoration work.” Homeless advocates, meanwhile, seized on the timing on Thursday as U.S. Forest Service officers blocked the access road.

“The fact that they are doing this with such vigor shortly after they announced that the forests would be opened up for logging I don’t think is a coincidence,” said Jesse Rabinowitz, spokesperson for the National Homelessness Law Center.

Driver possibly stricken in deadly Illinois crash

The Illinois State Police said Thursday that the woman who drove her Jeep through an after-school center in Chatham, Illinois, earlier this week could have experienced a medical episode before the crash, which killed three children and a teenager.

The driver, a 44-year-old Chatham resident, tested negative for alcohol and controlled substances in the aftermath, authorities said.

“Some evidence has been developed indicating the possibility of a medical emergency leading up to the crash,” Brendan F. Kelly, the director of the Illinois State Police, said at a news conference Thursday. “However, the investigation of this information and other evidence has not yet concluded, and will continue until all leads and research have been exhausted.”

The crash occurred Monday afternoon, when dozens of children were at the privately owned after-school center, YNOT Outdoors. The car left the road, veered through an open field and into the building. Once inside, the car burst through another wall and finally stopped when it hit a ballpark fence. Kelly said that data from the car would be analyzed as part of the investigation.

The driver, who was not injured, was taken to a hospital and released. No charges have been filed, and the driver is not in custody.

Lawsuit filed over migrant girl’s death

The death of an 8-year-old migrant girl in 2023 while she was in the custody of U.S. Customs and Border Protection prompted investigations and the removal of the agency’s chief medical officer. Now, two immigrant rights groups are seeking $15 million in damages on behalf of the girl’s family.

In a wrongful death claim filed with the federal government Thursday, lawyers for the family offer the most detailed public account yet of the life and death of the child, Anadith Danay Reyes Álvarez, and her family’s efforts to obtain answers about her care in federal custody.

Her death came during a record increase in migration, as the Biden administration struggled to curb illegal crossings and faced criticism about overcrowded detention facilities and the treatment of minors. Illegal crossings plunged in the final months of the Biden administration after a change in asylum policy and have remained very low under President Donald Trump. But the Trump administration has made families with children targets for detention and removal as Trump seeks to fulfill a campaign pledge to deport millions of immigrants living in the country illegally.

Gunman on motorcycle kills Kenyan lawmaker

A Kenyan lawmaker was gunned down on a busy Nairobi street by a motorcycle-riding assassin Wednesday evening, in what the police described as a “targeted and premeditated” attack.

The lawmaker, Charles Were, who was serving a second term in parliament, was in a vehicle stopped at a traffic light when he was killed, the police said. Witnesses reported that a person riding on the back of a motorcycle had hopped off and shot into the passenger side of Were’s car before being whisked away by the motorcycle’s driver, the police said.

A motive was not immediately clear. A police spokesperson said in a statement Wednesday that it was too early for authorities to provide additional details.

American won’t be charged with king insult

Regional prosecutors in Thailand said Thursday that they would not pursue charges against an American academic who was accused of insulting the Thai monarchy. But the charges under the country’s strict lèse-majesté laws have not been dropped entirely.

The academic, Paul Chambers, a lecturer in political science in northern Thailand, was arrested last month and later released on bail. Prosecutors in northern Thailand said in a news release that a regional police commander would review their decision not to prosecute him. If the commander disagrees, Thailand’s attorney general would typically have the final say on whether to prosecute Chambers.

Still, lawyers for Chambers, who have denied the accusations, called the prosecutors’ decision a hopeful sign in the case.

Man charged with fatal N.Y. subway stabbing

A 46-year-old man was charged Wednesday with fatally stabbing a rider on a New York City subway train last week after the two got into an argument during the morning rush.

The man, identified by police as Luis Jose-Duarte, was charged with manslaughter for his role in the death of the rider, John Sheldon, 38, according to the police. Jose-Duarte was arraigned Wednesday evening and pleaded not guilty.

The stabbing, the first homicide in the city’s subway system this year, took place Friday morning after Jose-Duarte and Sheldon began fighting on a downtown No. 5 train, the police said.

The men got into an argument after one stepped on the other’s shoe, a law enforcement official said.

World’s oldest person dies at 116 in Brazil

Sister Inah Canabarro, a Brazilian nun and teacher who was the world’s oldest person, died on Wednesday just weeks short of turning 117, her religious congregation said.

Canabarro died at home of natural causes, said her Teresian nun congregation, the Company of Saint Teresa of Jesus. She was confirmed in January as the world’s oldest person by LongeviQuest, an organization that tracks supercentenarians around the globe.

She would have turned 117 on May 27. According to LongeviQuest, the world’s oldest person is now Ethel Caterham, a 115-year-old British woman.
