An unidentified gunman killed two high-profile judges outside Iran’s Supreme Court on Saturday in what the authorities are calling a terrorist attack, according to state-run media.

The attacker opened fire on a square near the Supreme Court headquarters in the capital, Tehran, the Islamic Republic News Agency reported.

The judges, Ali Razini and Mohammad Moqiseh, had long careers and had presided over cases involving national security, espionage and terrorism, according to a statement by the judiciary and published by state media.

Both were heads of branches of the Supreme Court. A third judge was wounded in the attack.

The Iranian judiciary described the episode as a terrorist attack and the shootings as targeted assassinations, according to Mizan, another state news outlet

The attacker killed himself before the police could arrest him, Mizan reported. The police opened an investigation.

As president of South Korea, Yoon Suk Yeol lived in a luxurious hilltop mansion, threw parties and had a small army of personal guards. These days, he is alone in a 107-square-foot jail cell, eating simple food like noodles and kimchi soup, and sleeping on the floor.

This will be his new reality for a while yet, after he was formally arrested on insurrection charges early Sunday as part of an investigation into his ill-fated declaration of martial law last month.

Mr. Yoon, 64, has been in the Seoul Detention Center, a government-run jail south of Seoul, since Wednesday, when he became the first sitting president in South Korean history to be detained in a criminal investigation. When a district court in Seoul issued the warrant to arrest him, he went from being a temporary detainee to a criminal suspect facing an indictment and trial.

That change in status meant that Mr. Yoon was unlikely to leave jail any time soon. Within the next 18 days, criminal investigators and prosecutors were expected to indict him on charges of leading an insurrection during his short-lived martial law last month. If he is convicted, he will face life imprisonment or ​the death penalty.

Mr. Yoon’s new circumstances were symbolic of his dramatic fall from grace: from a swaggering head of state to an impeached president to an inmate accused of committing one of the worst offenses in South Korea’s criminal code. He is the first South Korean to face insurrection charges since the former military dictator Chun Doo-hwan, who was convicted in the 1990s.

As president, Mr. Yoon loved to throw parties, often inviting like-minded politicians to evening drinks and even cooking and serving ​rolled egg and barbecue to his presidential press corps. He showed off his well-honed entertaining skills ​abroad when he belted out “American Pie” during a White House dinner in 2023.​

Now, ​Mr. Yoon will wake up ​not to presidential aides and chefs catering to his needs, but to a simple jail breakfast usually made up of dumpling soup, bread or cereals. ​An average meal in jail costs $1.20.

The dramatic political upheaval he unleash​ed appears to have stunned him as much as everyday South Koreans.

“Ironically, it was after I was impeached that I truly realized​ that I am, indeed, the president,” Mr. Yoon said in a lengthy statement on Wednesday.

Many South Korean politicians and dignitaries​ — including two former presidents and Lee Jae-yong, the head of the Samsung conglomerate​ — have been held at the Seoul Detention Center in Uiwang, a city south of Seoul. When he was a prosecutor, Mr. Yoon helped put one of the two former presidents, Park Geun-hye, there on corruption charges. The jail also holds some of the country’s most infamous death row inmates​, including serial killers.

​Government officials said Mr. Yoon would get no special treatment, except that he ​would be kept in a room of his own, away from other detainees and inmates.​ After his formal arrest, he was expected to go through a simple medical checkup and receive a toothbrush and other necessities for ​jail life​. He would be assigned an inmate number​ and a pea​-green​ jail uniform.

His cell will have a TV set, a sink, a small cupboard, a reading desk that doubles as a dinner table, and a foldable mattress for sleeping. The cell has a toilet but no shower. The space will be monitored around the clock through closed-circuit television.

Mr. Yoon has been an avid follower of right-wing YouTubers who supported his government and spread conspiracy theories ​that depicted his domestic enemies as dangerous sympathizers with North Korea and China. Since he declared martial law on Dec. 3, Mr. Yoon has said his action was inspired ​in part by the same fear, indignation and suspicions spread by the extremists on YouTube.

The ​jail TV shows only programs authorized by the Ministry​ of Justice. ​Inmates have ​no access ​to the internet, including YouTube. At rallies calling for Mr. Yoon’s arrest in recent weeks, some protesters held signs that read: “Yoon Suk Yeol: It’s time for a digital detox!”

Yang Kyeung-soo, ​a labor union leader who had spent time in a solitary cell in the Seoul Detention Center​, posted jail survival tips on X. “You have to learn how to save warm water because you wash your own dishes​. If you eat everything they serve, you will gain weight quickly.”

​Mr. Yoon was expected to meet frequently with his attorneys in a visiting area to prepare for his trial​s. ​Separately, the country’s Constitutional Court is deliberating whether the National Assembly’s vote on Dec. 14 to impeach ​him was legitimate and if he should be formally removed from office.

Mr. Yoon’s martial law lasted only six hours because the opposition-dominated National Assembly voted it down. But during that brief ​period, he ordered military commanders to ​seize the Assembly​ and arrest his political enemies, according to prosecutors who have ​arrested and indicted the military generals accused of helping Mr. Yoon commit insurrection.

Mr. Yoon ​and his lawyers insisted that his imposition of martial law was a legitimate use of presidential power.

After they detained Mr. Yoon on Wednesday, officials from the country’s Corruption Investigation Office For ​High-ranking Officials ​questioned him until he was sent to rest in a cell at the Seoul Detention Center. But ​he has since refused to leave his cell to face more questioning​.

“He made his basic positions known during the first day of questioning, and he no longer feels a reason or need to subject himself to a question-and-answer type of interrogation,” said one of his lawyers, Seok Dong-hyeon.

When Ms. Park, the former president, was held in the detention center, die-hard supporters ​gathered near its walls every morning and shouted “Good morning, President Park Geun-hye!”

Since Mr. Yoon’s arrival, some supporters have camped outside, calling his impeachment and his arrest ​“null and void.​”

When we first watched the surveillance footage, we were stunned.

There was the Hungarian ambassador to Brazil pacing nervously in the embassy. There was Jair Bolsonaro, the former Brazilian president — fresh off court orders not to leave the country because of an intensifying criminal investigation — arriving at the gate. There were the embassy staff members hustling to the guest quarters with linens and a coffee maker.

And then, for two days, there was Mr. Bolsonaro wandering the parking lot, looking bored, and there were his security guards fetching pizza.

Given the circumstances — a politician facing potential imprisonment sleeping at a foreign embassy controlled by a political ally — it had all the hallmarks of a man seeking political asylum. Foreign embassies can be considered sovereign territory and have historically been used as refuge for people fleeing custody.

Colleagues and I published an article saying so, complete with clips from the footage.

In response, Mr. Bolsonaro’s lawyers issued a statement saying he had merely gone to the embassy to talk politics. Any suggestion otherwise, they said, was “fake news.”

Alexandre de Moraes, the Brazilian Supreme Court justice leading sprawling criminal investigations into the former president, later decided that Mr. Bolsonaro had not broken the law by sleeping at the embassy.

So when I sat down with Mr. Bolsonaro for an interview this week, I was eager to finally ask him why — in the middle of Brazil’s carnival, four days after the police confiscated his passport — he had decided to sleep in the small guest room of the Hungarian Embassy.

Here is an excerpt from our exchange, translated from Portuguese and edited for clarity.

Why did you sleep at the Hungarian Embassy for two nights?

Look, it was a question of time zones with whom I was talking. And that’s final.

But you slept there for two nights?

Yes.

Is that normal?

That’s up for me to decide.

You don’t have a bed in Brasília? (Brasília is Brazil’s capital.)

I do. I could’ve been fighting with my wife. I’m not saying. Just like when I talk to the authorities, I don’t say I did. Nothing leaks from me. Zero.

Have you slept at another embassy?

Who knows? I’m friends with Israel. I get along with countries in the Arab world. I’m not going to say what I do because that gives them a narrative to chase. I’m a free citizen.

The team of Alexandre de Moraes wanted to arrest me because I went without a passport. You don’t need a passport to enter an embassy.

You are a private citizen. You’re also a former president who talks about the importance of the truth. So it’s natural to want to understand why you slept at a foreign embassy four days after the authorities searched your home.

They could have arrested me during the search if they wanted. Anything I do is an attempt to hide to them. Was it refuge? Asylum? With asylum, you deal directly with the president.

Was it a bid for asylum? It seems strange to sleep in an embassy.

Isn’t it strange that I’m being persecuted? Everything I might say, the other side could go after me. I met with [President Viktor Orban of Hungary] in Argentina at [President Javier] Milei’s inauguration. I get along well with him.

It wasn’t a crime what I did. If there had been any crime, they would have arrested me.

[The embassy’s surveillance footage also showed a person visit Mr. Bolsonaro for 38 minutes. A Brazilian news outlet later reported it was his son, Carlos. Carlos was in the room with us.]

Carlos, you visited your father, right? What happened?

Carlos Bolsonaro: I just talked to my father about …

[Lawyer in the room interrupts to request to talk off the record.]

Jair Bolsonaro: Do you think I would have trouble leaving Brazil right now? No passport? Don’t a ton of illegal immigrants go to the United States? I’m an army captain. I’m used to the hardships out there.

OK. So why were you at the embassy?

Who knows? Maybe I have a lover there.

I’m not trying to be difficult, but I care about the truth, and you say you do, too. So I just want to understand.

It’s a secret. Maybe one day you’ll find out.

The mediating country Qatar on Saturday announced a time for the cease-fire agreement between Israel and Hamas to take effect the next day, setting off final preparations for a truce that much of the world hopes will end 15 months of destruction in Gaza.

The deal should go into effect at 8:30 a.m. local time on Sunday, said Majed al-Ansari, a spokesman for the Foreign Ministry of Qatar, which spent months alongside the United States and Egypt struggling to broker an agreement.

Israel’s government approved the deal early Saturday morning after hours of deliberations and amid internal rifts in the governing coalition of Prime Minister Benjamin Netanyahu. The approval cleared a final obstacle, raising hopes for Israelis who want to see loved ones returned and Gazans who have survived one of the most intense bombing campaigns of the 21st century.

“It’s a mix of joy, sadness and longing for a new beginning,” said Mariam Moeen Awwad, 23, who has been displaced from her home in northern Gaza six times since the war began.

Ms. Awad had planned to move into her newly furnished apartment with her husband in November 2023. The war derailed those plans, leaving the couple in an overcrowded property and eager to return home, she said, “if it’s even still there.”

In Israel, the authorities have started preparations to welcome home dozens of hostages, without knowing whether they will return malnourished, traumatized or dead.

In his first remarks since the cease-fire’s approval, Prime Minister Benjamin Netanyahu said in an address on Saturday night that 33 hostages would be released in the first phase of the deal, “most of them alive.”

Defending the deal, he argued also listed that Israel had made major strategic gains over the past several months, including the killing of top Hamas leaders. “As I pledged to you — we have changed the face of the Middle East,” he said.

Three reception points have been established to receive the hostages along the Gaza border, according to an Israeli military official. Those will be staffed by Israeli soldiers, as well as doctors and psychologists, said the official, who spoke on condition of anonymity in accordance with protocol.

The hostage release is expected to be the first such major exchange since a weeklong cease-fire early in the war.

“The ones who were freed back then were already poorly nourished,” Hagar Mizrahi, a senior Israeli health ministry official, said of the hostages freed during the 2023 truce. “Imagine their situation now, after an additional 400 days. We are extremely worried about this.”

Of the women, older men and other hostages set to be returned, many are believed to have been held in Hamas’s network of tunnels in Gaza, under conditions likely to leave physical and psychological scars. Israeli hospitals are preparing isolated areas where the hostages can begin recuperating in privacy.

“Last time, we saw the Red Cross transferring the hostages, and some of them were running to the relatives, hugging them,” said Einat Yehene, a clinical psychologist working with the Hostage Families Forum, an advocacy group. “It’s not going to be easy and similar this time, given the physical and the emotional conditions we expect.”

In exchange, hundreds of Palestinian prisoners are to be freed. The total number of prisoners to be released and their identities were among the many contentious points involved in the negotiations for a deal.

The new deal also calls for allowing 600 trucks carrying aid to enter Gaza daily and negotiations on the withdrawal of Israeli forces from the territory and a permanent end to the war.

Those negotiations are likely to be bitter and difficult, like the months of talks that yielded this week’s cease-fire agreement. Mr. Netanyahu is already facing an internal revolt within his governing coalition, which his far-right partners have threatened to quit over their opposition to the deal.

They have called for the war to continue to eradicate Hamas, which led the October 2023 attack on Israel that killed about 1,200 people, took another 250 hostage and started the war.

Mr. Netanyahu also faces pressure from the many Israelis who want all the hostages returned, and from the outgoing U.S. president, Joseph R. Biden Jr., and the president-elect, Donald J. Trump, who both want the war ended.

In his address, Mr. Netanyahu said the agreement preserves Israel’s right to return to the war against Hamas if it so chooses. The agreement also allows Israeli forces to remain in a buffer zone along Israel’s border with Gaza and Gaza’s border with Egypt, he added, at least during the initial phase.

“If we need to go back to fighting, we will do it in new ways and with great might,” he said.

Another uncertainty in how the deal might unfold arises from the chaotic, ruined conditions within Gaza, where tens of thousands of people have been killed since the war began and hundreds of thousands of others live without homes, clean water or ready supplies of food or medicine.

Israel’s campaign has left a power vacuum across much of Gaza, and lawlessness has proved a dangerous factor in efforts to get aid to people in need. Organized looting has repeatedly stripped trucks of supplies, including from a convoy of 100 trucks holding U.N. aid late last year.

Israel has continued striking Gaza since the cease-fire was announced, and over the past 24 hours, 23 Palestinians were killed and 83 others wounded, Gaza’s health ministry said on Saturday morning. More than 46,000 people have been killed in Gaza since the war began, according to the ministry, which does not distinguish between combatants and civilians.

Desperately needed aid is expected to pour into Gaza once the cease-fire begins. Egypt, which shares a border with the enclave, was intensifying preparations on Friday to deliver assistance including food and tents, according to Al Qahera News, an Egyptian state broadcaster.
