A court formally arrested the mayor of Istanbul, a key rival to President Recep Tayyip Erdogan, on Sunday and ordered him jailed pending the outcome of a trial on corruption charges.

Mayor Ekrem Imamoglu was detained following a raid on his residence earlier this week, sparking the largest wave of street demonstrations in Turkey in more than a decade. It also deepened concerns over democracy and rule of law in Turkey.

His imprisonment is widely regarded as a political move to remove a major contender from the next presidential race, currently scheduled for 2028. Government officials reject the accusations and insist that Turkey’s courts operate independently.

The prosecutor’s office said the court decided to jail Imamoglu on suspicion of running a criminal organization, accepting bribes, extortion, illegally recording personal data and bid-rigging. A request for him to be imprisoned on terror-related charges was rejected although he still faces prosecution. Following the court’s ruling, Imamoglu was transferred to Silivri prison, west of Istanbul.

The Interior Ministry later announced that Imamoglu had been suspended from duty as a “temporary measure.” The municipality had previously appointed an acting mayor from its governing council.

Alongside Imamoglu, 47 other people were also jailed pending trial, including a key aide and two district mayors from Istanbul, one of whom was replaced with a government appointee. A further 44 suspects were released under judicial control.

Interior Minister Ali Yerlikaya said Sunday that 323 people were detained the previous evening over disturbances at protests.

Largely peaceful protests across Turkey have seen hundreds of thousands come out in support of Imamoglu. However, there has been some violence, with police deploying water cannons, tear gas, pepper spray and firing plastic pellets at protesters in Istanbul, Ankara and Izmir, some of whom hurled stones, fireworks and other missiles at riot police.

The formal arrest came as more than 1.5 million members of the opposition Republican People’s Party, or CHP, began holding a primary presidential election to endorse Imamoglu, the sole candidate.

The party has also set up symbolic ballot boxes nationwide to allow people who are not party members to express their support for the mayor. Large crowds gathered early Sunday to cast a “solidarity ballot.”

“This is no longer just a problem of the Republican People’s Party, but a problem of Turkish democracy,” Fusun Erben, 69, said at a polling station in Istanbul’s Kadikoy district. “We do not accept our rights being so easily usurped. We will fight until the end.”

Speaking at a polling station in Bodrum, western Turkey, engineer Mehmet Dayanc, 38, said he feared that “in the end we’ll be like Russia, a country without an opposition, where only a single man participates in elections.”

In a message posted on social media, Imamoglu called on people to show “their struggle for democracy and justice to the entire world” at the ballot box. He warned Erdogan that he would be defeated by “our righteousness, our courage, our humility, our smiling face.”

“Honestly, we are embarrassed in the name of our legal system,” Ankara Mayor Mansur Yavas, a fellow member of Imamoglu’s CHP, told reporters after casting his vote, criticizing the lack of confidentiality in the proceedings.

CHP leader Ozgur Ozel said Imamoglu’s imprisonment was reminiscent of “Italian mafia methods.” Speaking at Istanbul City Hall, he added: “Imamoglu is on the one hand in prison and on the other hand on the way to the presidency.”

The Council of Europe, which focuses on promoting human rights and democracy, slammed the decision and demanded Imamoglu’s immediate release.

Under threat from the Trump administration, Columbia University agreed to implement a host of policy changes Friday, including overhauling its rules for protests and conducting an immediate review of its Middle Eastern studies department.

The changes, detailed in a letter sent by the university’s interim president, Katrina Armstrong, came one week after the Trump administration ordered the Ivy League school to enact those and other reforms or lose all federal funding, an ultimatum widely criticized in academia as an attack on academic freedom.

In her letter, Armstrong said the university would immediately appoint a senior vice provost to conduct a thorough review of the portfolio of its regional studies programs, “starting immediately with the Middle East.”

Columbia will also revamp its long-standing disciplinary process and bar protests inside academic buildings. Students will not be permitted to wear face masks on campus “for the purposes of concealing one’s identity.” An exception would be made for people wearing them for health reasons.

In an effort to expand “intellectual diversity” within the university, Columbia will also appoint new faculty members to its Institute for Israel and Jewish Studies department. It will also adopt a new definition of antisemitism and expand programming in its Tel Aviv Center, a research hub based in Israel.

The policy changes were largely in line with demands made on the university by the Trump administration, which pulled $400 million in research grants and other federal funding, and had threatened to cut more, over the university’s handling of protests against Israel’s military campaign in Gaza.

The White House has labeled the protests antisemitic, a label rejected by those who participated in the student-led demonstrations.

A message seeking comment was left with a spokesperson for the Education Department. As a “precondition” for restoring funding, federal officials demanded that the university to place its Middle Eastern, South Asian and African Studies Department under “academic receivership for a minimum of five years.”

Historians had described the order as an unprecedented intrusion on university rights long treated by the Supreme Court as an extension of the First Amendment.

On Friday, freedom of speech advocates immediately decried Columbia’s decision to acquiesce.

As congressional lawmakers scramble to respond to President Donald Trump’s slashing of the federal government, one group is already taking a front and center role: military veterans.

From layoffs at the Department of Veterans Affairs to a Pentagon purge of archives that documented diversity in the military, veterans have been acutely affected by Trump’s actions. And with the Republican president determined to continue slashing the federal government, the burden will only grow on veterans, who make up roughly 30% of the federal workforce and often tap government benefits they earned with their military service.

“At a moment of crisis for all of our veterans, the VA’s system of health care and benefits has been disastrously and disgracefully put on the chopping block by the Trump administration,” said Sen. Richard Blumenthal, the top Democrat on the Senate Veterans Affairs Committee, at a news conference last week.

Most veterans voted for Trump last year — nearly 6 in 10, according to AP Votecast, a nationwide survey of more than 120,000 voters. Yet congressional Republicans are standing in support of Trump’s goals even as they encounter fierce pushback in their home districts. At a series of town halls this week, veterans angrily confronted Republican members as they defended the cuts made under Trump adviser Elon Musk’s Department of Government Efficiency.

“Do your job!” Jay Carey, a military veteran, yelled at Republican Rep. Chuck Edwards at a town hall in North Carolina.

“I’m a retired military officer,” an attendee at another forum in Wyoming told Republican Rep. Harriet Hageman before questioning whether DOGE had actually discovered any “fraud.”

Although Republican House Speaker Mike Johnson advised his members to skip the town halls and claimed that they were being filled with paid protesters, some Republicans were still holding them and trying to respond to the criticism.

“It looks radical, but it’s not. I call it stewardship, in my opinion,” Republican Rep. Gus Bilirakis of Florida said on a tele-town hall. “I think they’re doing right by the American taxpayer. And I support that principle of DOGE.”

Still, some Republicans have expressed unease with the seemingly indiscriminate firings of veterans, especially when they have not been looped in on the administration’s plans. At a town hall on Friday, Texas Republican Rep. Dan Crenshaw told the audience, “We’re learning about this stuff at the speed of light, the way you are. I think there’s been some babies thrown out with the bath water here, but we’re still gathering information on it.”

Crenshaw, a former Navy SEAL, added, “If you’re doing a job that we need you to do, you’re doing it well, yeah, we’ve got to fight for you.”

The Republican chair of the House Veterans Affairs Committee, Rep. Mike Bost, assured listeners on a tele-town hall last week that he and Veterans Affairs Secretary Doug Collins are talking regularly. As the VA implements plans to cut roughly 80,000 jobs, Bost has said he is watching the process closely, but he has expressed support and echoed Collins’ assurances that veterans’ health care and benefits won’t be slashed.

“They’ve cut a lot, but understand this: Essential jobs are not being cut,” Bost said, but then added that his office was helping alert the VA when people with essential jobs had in fact been terminated.

Two federal judges this month ordered the Trump administration to rehire the probationary employees who were let go in the mass firings. At the VA, some of those employees have now been put on administrative leave, but a sense of dread and confusion is still hanging over much of the federal workforce.

The new Austrian government said Wednesday that family reunion procedures for migrants will be immediately halted because the country is no longer able to absorb newcomers adequately.

The measure is temporary and intended to ensure that those migrants who are already in the country can be better integrated, Chancellor Christian Stocker from the conservative Austrian People’s Party said.

“Austria’s capacities are limited, and that is why we have decided to prevent further overloading,” Stocker said.

The new measure means that migrants with so-called protected status — meaning they cannot be deported — are no longer allowed to bring family members still living in their home countries to Austria.

The new three-party coalition made up of the People’s Party, the center-left Social Democrats and the liberal Neos, has said that curbing migration is one of its top issues and vowed to implement strict new asylum rules.

Official figures show that 7,762 people arrived in Austria last year as part of family reunion procedures for migrants. In 2023 the figure was 9,254. Most new arrivals were minors.

Migrants who are still in the asylum process or have received a deportation order are not allowed in the first place to bring family members from their countries of origin.

Most recent asylum seekers came from Syria and Afghanistan, the Austrian chancellery said in a statement.  The European Union country has 9 million inhabitants.

Stocker said the measure was necessary because “the quality of the school system, integration and ultimately the security of our entire systems need to be protected — so that we do not impair their ability to function.”

The government said it had already informed the EU of its new measures. It denied to say for how long it would put family reunions on hold.

“Since last summer, we have succeeded in significantly reducing family reunification,” Interior Minister Gerhard Karner said. “Now we are creating the legal basis to ensure this stop is sustainable.”

All over the continent, governments have been trying to cut the number of migrants. The clamp-down on migrants is a harsh turnaround from ten years ago, when countries like Germany and Sweden openly welcomed more than 1 million migrants from war-torn countries such as Syria, Afghanistan and Iraq.

Many communities and towns in other countries, such as Germany, also say they no longer have capacities to find shelter or homes for migrants.

The EU is trying to keep more migrants from entering its 27-country bloc and move faster to deport those whose asylum procedures are rejected.

On Tuesday, the EU unveiled a new migration proposal that envisions the opening of so-called “return hubs” to be set up in third countries to speed up the deportation for rejected asylum-seekers.

So far, only 20% of people with a deportation order are effectively removed from EU territory, according to the European Commission.

Japan’s trade minister said this week that he has failed to win assurances from U.S. officials that the key U.S. ally will be exempt from tariffs, some of which take effect on Wednesday.

Yoji Muto was in Washington for last ditch negotiations over the tariffs on a range of Japanese exports including cars, steel and aluminum.

Muto said Monday in Washington that Japan, which contributes to the U.S. economy by heavily investing and creating jobs in the United States, “should not be subject to” 25% tariffs on steel, aluminum and auto exports to America.

His meetings with U.S. Commerce Secretary Howard Lutnick, U.S. Trade Representative Jamieson Greer and White House economic advisor Kevin Hassett came just two days before the steel and aluminum tariffs are due to take effect. President Donald Trump has also said a possible 25% tariff on imported foreign autos could take effect in early April.

Muto said the U.S. officials acknowledged Japanese contributions and agreed to continue talks, but did not approve his request for Japan’s exemption from the steep import duties.

“We did not receive a response that Japan will be exempt,” Muto told reporters. “We must continue to assert our position.”

As Trump’s tariff threats have triggered tensions and vows of retaliation from Canada, Mexico and China, Japan has been working to firm up ties with other countries.

Last week, the foreign and trade ministers from Japan and Britain gathered in Tokyo for their first “two-plus-two” economic dialogue. They agreed to stand up for “fair, rules-based international trade,” though nobody directly mentioned Trump.

Japan depends heavily on exports and the auto tariffs would hurt, because vehicles are its biggest export and the United States is their top destination.

“Clearly companies in Japan are very concerned,” said Rintaro Nishimura, political analyst and associate at Japan Practice of The Asia Group. “Obviously the auto is the crown jewel for Japan, especially in the context of these tariffs.” He says they are concerned also because the Trump administration is carrying it out in just two months after taking office.

Trump also has criticized Japan’s contributions to the two countries’ mutual defense arrangements, adding to tensions with Tokyo.

Muto said the two sides agreed to keep discussing to find ways to establish a “win-win” relationship that would serve national interests of both countries.

The two sides also discussed energy cooperation, including joint development of liquefied natural gas reserves in Alaska, which Trump and Prime Minister Shigeru Ishiba agreed on during Ishiba’s visit to the White House in February.
