DUBAI, United Arab Emirates (AP) — The head of Iran’s judiciary signaled Wednesday there would be fast trials and executions ahead for those detained in nationwide protests despite a warning from U.S. President Donald Trump.

The comments from Iran’s judiciary chief Gholamhossein Mohseni-Ejei come as activists had warned hangings of those detained could come soon. Already, a bloody security force crackdown on the demonstrations has killed at least 2,571, the U.S.-based Human Rights Activists News Agency reported. That figure dwarfs the death toll from any other round of protest or unrest in Iran in decades and recalls the chaos surrounding the country’s 1979 Islamic Revolution.

Trump repeatedly has warned that the United States may take military action over the killing of peaceful protesters, just months after it bombed Iranian nuclear sites during a 12-day war launched by Israel against the Islamic Republic in June.

Meanwhile Wednesday, Iran held a mass funeral of 300 security force members killed in the demonstrations. Tens of thousands of mourners attended, holding Iranian flags and photos of Ayatollah Ali Khamenei. The caskets, covered in Iranian flags, stood stacked at least three high. Red and white roses and framed photographs of people who were killed covered them.

People elsewhere remained fearful in the streets. Plainclothes security forces still milled around some neighborhoods, though anti-riot police and members of the paramilitary Revolutionary Guard’s all-volunteer Basij force appeared to have been sent back to their barracks.

“We are very frightened because of these sounds (of gunfire) and protests,” said one mother of two children shopping for fruits and vegetables Wednesday, who spoke on condition of anonymity for fear of reprisals. “We have heard many are killed and many are injured. Now peace has been restored but schools are closed and I’m scared to send my children to school again.”

Ahmadreza Tavakoli, 36, told The Associated Press he witnessed one demonstration in Tehran and was shocked by the use of firearms by authorities.

“People were out to express themselves and protest, but quickly it turned into a war zone,” Tavakoli said. “The people do not have guns. Only the security forces have guns.”

‘We have to do it quickly’

Mohseni-Ejei made the comment in a video shared by Iranian state television online.

“If we want to do a job, we should do it now. If we want to do something, we have to do it quickly,” he said. “If it becomes late, two months, three months later, it doesn’t have the same effect. If we want to do something, we have to do that fast.”

His comments stand as a direct challenge to Trump, who warned Iran about executions an interview with CBS aired Tuesday.

“We will take very strong action,” Trump said. “If they do such a thing, we will take very strong action.”

“We don’t want to see what’s happening in Iran happen. And you know, if they want to have protests, that’s one thing, when they start killing thousands of people, and now you’re telling me about hanging — we’ll see how that works out for them. It’s not going to work out good.”

One Arab Gulf diplomat told the AP that major Mideast governments had been discouraging the Trump administration from launching a war now with Iran, fearing “unprecedented consequences” for the region that could explode into a “full-blown war.” The diplomat spoke on condition of anonymity because he wasn’t authorized to speak to journalists.

Meanwhile, activists said Wednesday that Starlink was offering free service in Iran. The satellite internet service has been key in getting around an internet shutdown launched by the theocracy on Jan. 8. Iran began allowing people to call out internationally on Tuesday via their mobile phones, but calls from people outside the country into Iran remain blocked.

“We can confirm that the free subscription for Starlink terminals is fully functional,” said Mehdi Yahyanejad, a Los Angeles-based activist who has helped get the units into Iran. “We tested it using a newly activated Starlink terminal inside Iran.”

Starlink itself did not immediately acknowledge the decision.

Security service personnel also apparently were searching for Starlink dishes, as people in northern Tehran reported authorities raiding apartment buildings with satellite dishes. While satellite television dishes are illegal, many in the capital have them in homes, and officials broadly had given up on enforcing the law in recent years.

Death toll continues to rise

The Human Rights Activists News Agency said 2,403 of the dead were protesters and 147 were government-affiliated. Twelve children were killed, along with nine civilians it said were not taking part in protests. More than 18,100 people have been detained, the group said.

Gauging the demonstrations from abroad has grown more difficult, and the AP has been unable to independently assess the toll given the communications being disrupted in the country.

MINNEAPOLIS (AP) — Minnesota and its two largest cities sued the Trump administration Monday to try to stop an immigration enforcement surge that led to the fatal shooting of a Minneapolis woman by a federal officer and evoked outrage and protests across the country.

The state, joined by Minneapolis and St. Paul, said the Department of Homeland Security is violating the First Amendment and other constitutional protections. The lawsuit seeks a temporary restraining order to halt the enforcement action or limit the operation.

“This is, in essence, a federal invasion of the Twin Cities in Minnesota, and it must stop,” state Attorney General Keith Ellison said at a news conference. “These poorly trained, aggressive and armed agents of the federal state have terrorized Minnesota with widespread unlawful conduct.”

Homeland Security is pledging to put more than 2,000 immigration officers into Minnesota and says it has made more than 2,000 arrests since December. Immigration and Customs Enforcement has called the surge its largest enforcement operation ever.

Tension brimmed again Monday, five days after Renee Good was shot in the head by an ICE officer while behind the wheel of her SUV. From a large school walkout to emotional visits to a flower-covered memorial for Good to agents firing tear gas to break up crowds, Minneapolis remained on edge in the aftermath of the shooting.

There have been dozens of protests or vigils across the U.S. in recent days to honor the 37-year-old mother of three and to passionately criticize the Trump administration’s tactics.

Since the deployment in the Twin Cities, whistle-burst warnings by activists are commonly heard when immigration agents flood streets. Witnesses have regularly posted video of federal officers using tear gas to discourage the public from following them.

Feds say they’re protecting the public

The Minnesota lawsuit accuses the Republican Trump administration of violating free speech rights by focusing on a progressive state that favors Democrats and welcomes immigrants.

“They’re targeting us based on what we look and sound like. Our residents are scared. And as local officials, we have a responsibility to act,” said St. Paul Mayor Kaohly Her, who was born in Laos.

In response, Homeland Security spokesperson Tricia McLaughlin accused Minnesota officials of ignoring public safety.

“President Trump’s job is to protect the American people and enforce the law — no matter who your mayor, governor, or state attorney general is,” McLaughlin said. “That’s what the Trump administration is doing; we have the Constitution on our side on this, and we look forward to proving that in court.”

The Trump administration has repeatedly defended the immigration agent who shot Good, saying she and her vehicle presented a threat. But that explanation has been widely panned by Minnesota Gov. Tim Walz, Minneapolis Mayor Jacob Frey and others based on videos of the confrontation.

The government also faces a new lawsuit over a similar immigration crackdown in Illinois. More than 4,300 people were arrested last year in “Operation Midway Blitz” as masked agents swept the Chicago area. The lawsuit by the city and state says the campaign had a chilling effect, making residents afraid to leave home.

The lawsuit seeks restrictions on certain tactics, among other remedies. McLaughlin called it “baseless.”

Students walk out of school

Hundreds of students on Monday walked out of Roosevelt High School in Minneapolis, where federal agents had deployed tear gas on students and staff last week. Adults wearing safety vests cleared traffic, and many parents who are Roosevelt alumni showed up in old school wear.

Marchers held signs that said, “ICE out” and “Welcome to Panem,” a reference to the dystopian society from the “Hunger Games” book series.

Agents also fired tear gas to break up a crowd of people who showed up to see the aftermath of a car crash just a few blocks from where Good was killed. A crowd emerged to witness a man being questioned by agents who had rear-ended his car.

“I’m glad they didn’t shoot me or something,” Christian Molina told reporters.

Standing near his mangled fender, he wondered aloud: “Who’s going to pay for my car?”

In St. Cloud, 65 miles (104 kilometers) northwest of Minneapolis, hundreds of people gathered outside a strip of Somali-run businesses when news spread that dozens of ICE officers were there.

Meanwhile, in Portland, Oregon, federal authorities filed charges against a Venezuelan national who was one of two people shot there by U.S. Border Patrol on Thursday. The U.S. Justice Department said the man used his pickup truck to strike a Border Patrol vehicle and escape the scene with a woman.

They were shot and eventually arrested. Their wounds were not life-threatening. The FBI said there was no video of the incident, unlike the Good shooting.

WASHINGTON (AP) — Federal Reserve Chair Jerome Powellsaid Sunday the Department of Justice has served the central bank with subpoenas and threatened it with a criminal indictment over his testimony this summer about the Fed’s building renovations.

The move represents an unprecedented escalation in President Donald Trump’s battle with the Fed, an independent agency he has repeatedly attacked for not cutting its key interest rate as sharply as he prefers. The renewed fight will likely rattle financial markets Monday and could over time escalate borrowing costs for mortgages and other loans.

The subpoenas relate to Powell’s testimony before the Senate Banking Committee in June, the Fed chair said, regarding the Fed’s $2.5 billion renovation of two office buildings, a project that Trump has criticized as excessive.

Powell on Sunday cast off what has up to this point been a restrained approach to Trump’s criticisms and personal insults, which he has mostly ignored. Instead, Powell issued a video statement in which he bluntly characterized the threat of criminal charges as simple “pretexts” to undermine the Fed’s independence when it comes to setting interest rates.

“The threat of criminal charges is a consequence of the Federal Reserve setting interest rates based on our best assessment of what will serve the public, rather than following the preferences of the President,” Powell said. “This is about whether the Fed will be able to continue to set interest rates based on evidence and economic conditions — or whether instead monetary policy will be directed by political pressure or intimidation.”

It’s a sharp departure from the Fed’s understated response to Trump this year. The central bank has attempted to placate the administration by dialing back some policies, such as efforts to consider the impact of climate change on the banking system, that the administration clearly opposed.

The renewed attacks on the Fed’s independence, and Powell’s full-throated defense, reignite what had appeared to be a dormant battle between Trump and the chair he appointed in 2017. The subpoenas will renew fears that the Fed’s independence from day-to-day politics will be compromised, which could undermine global investors’ confidence in U.S. Treasury securities.

“We expect the dollar, bonds and stocks to all fall in Monday trading in a sell-America trade similar to that in April last year at the peak of the tariff shock and earlier threat to Powell’s position as Fed chair,” Krishna Guha, an analyst at Evercore ISI, an investment bank, wrote in a note to clients.

“We are stunned by this deeply disturbing development which came out of the blue after a period in which tensions between Trump and the Fed seemed to be contained,” Guha added.

In a brief interview with NBC News Sunday, Trump insisted he didn’t know about the investigation into Powell. When asked if the investigation is intended to pressure Powell on rates, Trump said, “No. I wouldn’t even think of doing it that way.”

Powell’s term as chair ends in May, and Trump administration officials have signaled that he could name a potential replacement this month. Trump has also sought to fire Fed governor Lisa Cook, an unprecedented step, though she has sued to keep her job and courts have ruled she can remain in her seat while the case plays out. The Supreme Court will hear arguments in that case Jan. 21.

At the Senate Banking Committee hearing in June, Chairman Tim Scott, a Republican from South Carolina, said the Fed’s building renovation included “rooftop terraces, custom elevators that open into VIP dining rooms, white marble finishes, and even a private art collection.”

Powell disputed those details in his testimony, saying “there’s no new marble. … there are no special elevators” and added that some of the controversial items are “not in the current plan.” In July, Russell Vought, director of the Office of Management and Budget, said in a letter to Powell that his testimony about changes to the building plans “raises serious questions about the project’s compliance” with previous plans approved by a planning commission.

Still, later that month, Trump visited the building site and, while standing next to Powell, overstated the cost of the renovation. Later that day, Trump, speaking to reporters, downplayed any concerns with the renovation. He said, “they have to get it done” and added, “Look, there’s always Monday morning quarterbacks. I don’t want to be that. I want to help them get it finished.”

When asked if it was a firing offense, Trump said, “I don’t want to put that in this category.”

The Justice Department in a statement Sunday said it can’t comment on any particular case, but added that Attorney General Pam Bondi “has instructed her US Attorneys to prioritize investigating any abuse of tax payer dollars.”

Timothy Lauer, a spokesperson for U.S. Attorney Jeanine Pirro’s office, said they don’t comment on ongoing investigations.

With the subpoenas, Powell becomes the latest perceived adversary of the president to face a criminal investigation by the Trump administration’s Justice Department. Trump himself has urged prosecutions of his political opponents, obliterating institutional guardrails for a Justice Department that for generations has taken care to make investigative and prosecutorial decisions independent of the White House.

The potential indictment has already drawn concern from one Republican senator, who said he’ll oppose any future nominee to the central bank, including any replacement for Powell, until “this legal matter is fully resolved.”

“If there were any remaining doubt whether advisers within the Trump Administration are actively pushing to end the independence of the Federal Reserve, there should now be none,” said North Carolina Sen. Thom Tillis, who sits on the Banking Committee, which oversees Fed nominations. “It is now the independence and credibility of the Department of Justice that are in question.”
