DUBAI, United Arab Emirates (AP) — Days of protests in Iran over rising fuel prices and a subsequent government crackdown have killed at least 106 people across the Islamic Republic, Amnesty International said Tuesday, citing “credible reports.”

Iran’s government, which has not made nationwide numbers available for the toll of the unrest that began Friday, did not immediately respond to the report. A request for comment to its mission at the United Nations was not immediately acknowledged.

The Amnesty report comes after a U.N. agency earlier said it feared the unrest may have killed “a significant number of people.” Amnesty added that it “believes that the real death toll may be much higher, with some reports suggesting as many as 200 have been killed.”

Iranian authorities have not offered a definitive account of how many people have been arrested, injured or killed in the protests that spread quickly across at least 100 cities and towns. Authorities shut down internet access to the outside world Saturday, an outage that persisted Monday in the nation of 80 million.

That has left only state media and government officials to tell their story. State television showed video Tuesday of burned Qurans at a mosque in the suburbs of the capital, Tehran, as well as pro-government rallies, part of its efforts to both demonize and minimize the protests.

Absent in the coverage, though, was an acknowledgement of what sparked the demonstrations in the first place. The jump in gasoline prices represents yet another burden on Iranians who have suffered through a painful currency collapse, following President Donald Trump’s unilateral withdrawal of the United States from Iran’s 2015 nuclear deal with world powers, and the re-imposition of crippling U.S. economic sanctions.

Relatively moderate President Hassan Rouhani has promised that the fuel price increase will be used to fund new subsidies for poor families. But the decision has unleashed widespread anger among Iranians, like Maryam Kazemi, a 29-year-old accountant in the southern Tehran suburb of Khaniabad, who said the new cost of fuel was “putting pressure on ordinary people.”

“It was a bad decision at a bad time. The economic situation has long been difficult for people, and Rouhani unexpectedly implemented the decision on fuel,” she said.

Amnesty said it gathered its figures from interviewing journalists and human rights activists, then cross-checked the information. In its breakdown, it showed the hardest-hit areas as the western Kermanshah province and its oil-rich southwestern province of Khuzestan. Many online videos released before the internet outage showed unrest there.

“Video footage shows security forces using firearms, water cannons and tear gas to disperse protests and beating demonstrators with batons,” Amnesty said. “Images of bullet casings left on the ground afterwards, as well as the resulting high death toll, indicate that they used live ammunition.”

Amnesty, citing eyewitnesses corroborated by video footage, said snipers also shot into crowds of people from rooftops and, in one case, a helicopter.

So far, scattered reports in state-run and semiofficial media have reported only six deaths.

The office of the U.N. High Commissioner for Human Rights earlier issued a statement saying it was “deeply concerned” about reports of live ammunition being used against demonstrators. It also urged protesters to demonstrate peacefully.

“We are especially alarmed that the use of live ammunition has allegedly caused a significant number of deaths across the country,” spokesman Rupert Colville said in a statement.

Colville added that it has been “extremely difficult” to verify the overall death toll.

Meanwhile, an article published Tuesday in the hard-line Kayhan newspaper suggested that executions loomed for those who led violent protests. Though the state-owned newspaper has a small circulation, its managing editor Hossein Shariatmadari was personally appointed by Iran’s Supreme Leader Ayatollah Ali Khamenei.

“Some reports say that the judiciary considers execution by hanging for the riot leaders a definite punishment,” Kahyan said, without elaborating.

It also repeated an allegation that protest leaders came from abroad. Khamenei on Sunday specifically named those aligned with the family of Iran’s late shah, ousted 40 years ago, and an exile group called the Mujahedeen-e-Khalq. The MEK calls for the overthrow of Iran’s government and enjoys the support of Trump’s personal lawyer, Rudy Giuliani.

Police and security forces remained on the streets of Tehran on Tuesday, but in lower numbers. Traffic also appeared to be flowing better, after part of the demonstrations saw people abandon their cars on major roadways.

Authorities postponed four soccer matches in different parts of the country scheduled for Thursday and Friday, the Iranian weekend, according to the semiofficial ISNA news agency. With the internet outage and phone services spotty, it remained difficult to know the situation in some regions.

The protests were prompted by a plunging economy. Many Iranians have seen their savings evaporate amid scarce jobs and the collapse of the national currency, the rial, since Trump withdrew Washington from the nuclear deal over a year ago and imposed sanctions. The rial now trades at over 123,000 to $1, compared to 32,000 to $1 at the time the deal took effect.

Cheap gasoline is practically considered a birthright in Iran, home to the world’s fourth-largest crude oil reserves despite decades of economic woes since its 1979 Islamic Revolution. Gasoline remains among the cheapest in the world, with the new prices jumping 50% to a minimum of 15,000 rials per liter. That’s 12 cents a liter, or about 50 cents a gallon. A gallon of regular gas in the U.S. costs $2.59 by comparison.

The U.N. rights office addressed that background of economic anger across Iran in its statement.

“Protests of this nature and on this scale are an indication of deep-rooted and often well-founded grievances that cannot simply be brushed aside,” Colville said.

Those grievances could be heard in Khaniabad and elsewhere around Tehran. Several described taking part in peaceful protests later hijacked by violent masked demonstrators. Others heard gunfire.

“We were out to protest the gasoline price on Saturday,” said Reza Nobari, a 33-year-old car mechanic. “Suddenly a group of six or seven who covered their faces appeared together and started to break the windows of a bank. This wasn’t what we were out for.”

Jafar Abbasi, a 58-year-old who runs a dairy, said he saw another group of people who arrived in a van smash the windows of nearby shops.

“Some looted the place and some other quickly disappeared,” he said.

He added: “This is all the result of Rouhani’s decision to increase the price of fuel.”
