DUBAI, United Arab Emirates (AP) — Clashes between Iranian security forces and protesters angry over the death of a 22-year-old woman in police custody have killed at least nine people since the violence erupted over the weekend, according to a tally Thursday by The Associated Press.

The scope of Iran’s ongoing unrest, the worst in several years, still remains unclear as protesters in more than a dozen cities — venting anger over social repression and the country’s mounting crises — continue to encounter security and paramilitary forces.

To prevent protests from spreading, Iran’s biggest telecom operator largely shut down mobile internet access again Thursday, said Netblocks, a group that monitors internet access, describing the restrictions as the most severe since 2019.

An anchor on Iran’s state television suggested the death toll from the mass protests could be as high as 17 on Thursday, but did not say how he reached that figure.

In a country where radio and television stations already are state-controlled and journalists regularly face the threat of arrest, the paramilitary Revolutionary Guard urged the judiciary on Thursday to prosecute “anyone who spreads fake news and rumors” on social media about the unrest. Widespread outages of Instagram and WhatsApp, which are used by protesters, also continued Thursday.

WhatsApp tweeted that it was “working to keep our Iranian friends connected and will do anything within our technical capacity to keep our service up and running.”

The demonstrations in Iran began as an emotional outpouring over the death of Mahsa Amini, a young woman held by the country’s morality police for allegedly violating its strictly enforced dress code. Her death has sparked sharp condemnation from the United States, the European Union and the United Nations.

The U.S. government imposed sanctions on the morality police and leaders of other Iranian security agencies, saying they “routinely employ violence to suppress peaceful protesters.”

Iranian police say Amini died of a heart attack and was not mistreated, but her family has cast doubt on that account. Independent experts affiliated with the U.N. said Thursday that reports suggested she was severely beaten by the morality police, without offering evidence.

In New York, on the sidelines of the U.N. General Assembly, Iranian President Ebrahim Raisi said the death must be “steadfastly” investigated. But he also turned the tables on the country he was visiting for the U.N. General Assembly.

“What about the death of Americans at the hands of U.S. law enforcement?” Raisi asked about his country’s rival nation. He called for the “same standard” around the world in dealing with such deaths at the hands of authorities and lamented what he said were “double standards” in the West.

Of Amini’s death, he said authorities were doing what they needed to do. “It must certainly be investigated,” he said. “I contacted her family at the very first opportunity and I assured them we would continue steadfastly to investigate that incident. ... Our utmost preoccupation is the safeguarding of the rights of every citizen.”

Niloufar Hamedi, a journalist who took photographs at the hospital after Amini’s death, was arrested in Iran on Thursday, according to the reporter’s lawyer, Mohammadali Kamfirouzi. He said her house was raided. There was no official comment.

The protests have grown in the last five days into an open challenge to the government, with women removing and burning their state-mandated headscarves in the streets and Iranians calling for the downfall of the Islamic Republic itself.

“Death to the dictator!” has been a common cry in the protests.

They are the most serious demonstrations since 2019, when protests erupted over a government hike in the price of gasoline. Rights groups say hundreds were killed in the crackdown that followed, the deadliest violence since the 1979 Islamic Revolution.

The latest protests are similarly widespread, but seem to have much broader support among the population, with Iranians of all walks of life expressing fury at Amini’s death and the government’s treatment of women.

Iran’s state-run media this week reported demonstrations in at least 13 cities, including the capital, Tehran. Videos online show security forces firing tear gas and water canons to disperse hundreds of protesters. London-based Amnesty International reported that officers also fired birdshot and beat protesters with batons.

Footage on social media from the northern city of Tabriz shows a young man allegedly shot by security forces bleeding out in the street as protesters shout for help.

Another video showed a policeman firing a shotgun at a demonstrator who was tearing down a pro-government billboard in the North Khorasan province. It’s unclear if he was wounded.

In another video, protesters can be seen torching a massive billboard showing Qassem Soleimani — Iran’s top general who was killed in a U.S. airstrike — in his hometown of Kerman. Soleimani has iconic status among government supporters.

At least nine people have died in the confrontations, according to an AP count based on statements from Iran’s state-run and semiofficial media. In a statement on Thursday, the Guard blamed the unrest on “Iran’s enemies.”

In Amini’s home province of Kurdistan, the provincial police chief said four protesters were shot dead. In Kermanshah, the prosecutor said two protesters were killed, insisting that the bullets were not fired by Iran’s security forces.

Three men affiliated with the Basij, a volunteer force under the Guard, were killed in clashes in the cities of Shiraz, Tabriz and Mashhad, semiofficial media reported, bringing the death toll acknowledged by officials to at least nine on both sides.

In the northern province of Mazandaran, angry crowds damaged or set fire to over 40 government properties and wounded 76 security officers, Rouhollah Solgi, the deputy governor, said.

Iran has grappled with waves of protests in the recent past, mainly over a long-running economic crisis exacerbated by Western sanctions linked to its nuclear program. Citizens also blame government corruption and mismanagement.

The Biden administration and European allies have been working to revive the 2015 Iran nuclear accord, in which Iran curbed its nuclear activities in exchange for sanctions relief, but the talks have been deadlocked for months.

From New York, where Raisi took the stage Wednesday at the U.N. General Assembly, CNN’s chief international anchor Christiane Amanpour said she had planned to confront Raisi about the protests in what would be his first U.S.-based interview.

But Amanpour wrote on Twitter that Raisi was a no-show. An aide told her the president refused to take part unless she wore a headscarf, given the “situation in Iran.” The Iranian government has not commented on the incident.

“I couldn’t agree to this unprecedented and unexpected condition,” the British-Iranian anchor wrote beside a photo of Raisi’s empty chair.
