Iran’s supreme leader on Sunday cautiously backed the government’s decision to raise gasoline prices by 50% after days of widespread protests, calling those who attacked public property during demonstrations “thugs” and signaling that a potential crackdown loomed.

The government shut down internet access across the nation of 80 million people to staunch demonstrations that took place in a reported 100 cities and towns. That made gauging if unrest continued increasingly difficult. Images published by state and semiofficial media showed the scale of the damage in images of burned gas stations, pillaged banks and roadways littered with debris.

Since the hike, demonstrators have abandoned cars along major highways and joined mass protests in the capital, Tehran, and elsewhere. Some protests turned violent, with demonstrators setting fires as gunfire rang out.

It remains to be seen how many people were arrested, injured or killed. Videos from the protests have shown people gravely wounded.

Iranian authorities on Sunday raised the official death toll in the violence to at least three. Attackers targeting a police station in the western city of Kermanshah on Saturday killed an officer, the state-run IRNA news agency reported Sunday. A lawmaker said another person was killed in a suburb of Tehran. Earlier, one man was reported killed Friday in Sirjan, a city some 800 kilometers (500 miles) southeast of Tehran.

In an address aired Sunday by state television, Ayatollah Ali Khamenei said “some lost their lives and some places were destroyed,” without elaborating. He called the protesters “thugs” who had been pushed into violence by counterrevolutionaries and foreign enemies of Iran.

Khamenei 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 President Donald Trump’s personal lawyer, Rudy Giuliani.

“Setting a bank on fire is not an act done by the people. This is what thugs do,” Khamenei said.

The supreme leader carefully backed the decision of Iran’s relatively moderate President Hassan Rouhani and others to raise gasoline prices. While Khamenei dictates the country’s nuclear policy amid tensions with the U.S. over its unraveling 2015 accord with world powers, he made a point to say he wasn’t an “expert” on the gasoline subsidies.

Khamenei ordered security forces “to implement their tasks” and for Iran’s citizens to keep clear of violent demonstrators. Iran’s Intelligence Ministry said the “key perpetrators of the past two days’ riot have been identified and proper action is ongoing.”

That seemed to indicate a crackdown could be looming. Economic protests in late 2017 into 2018, as well as those surrounding its disputed 2009 presidential election, were met with a heavy reaction by the police and the Basij, the all-volunteer force of Iran’s paramilitary Revolutionary Guard.

The semiofficial Fars news agency, close to the Guard, put the total number of protesters at over 87,000, saying demonstrators ransacked some 100 banks and stores in the country. Authorities arrested some 1,000 people, Fars reported, citing unnamed security officials for the information.

The protests have put renewed pressure on Iran’s government as it struggles to overcome the U.S. sanctions that have strangled the economy since Trump unilaterally withdrew America from the nuclear deal over a year ago.

While representing a political risk for Rouhani ahead of February parliamentary elections, the demonstrations also show widespread anger among the Iranian people, who have seen their savings evaporate amid scarce jobs and the collapse of the national currency, the rial.

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 in the country remains among the cheapest in the world, with the new prices jumping 50% to a minimum of 15,000 rials per liter. That’s 13 cents a liter, or about 50 cents a gallon. A gallon of regular gasoline in the U.S. costs $2.60 by comparison.

Iranian internet access saw disruptions and outages Friday night into Saturday, according to the group NetBlocks, which monitors worldwide internet access. By Saturday night, connectivity had fallen to just 7% of ordinary levels.

“The ongoing disruption is the most severe recorded in Iran since President Rouhani came to power, and the most severe disconnection tracked by NetBlocks in any country in terms of its technical complexity and breadth,” the group said. The internet firm Oracle called it “the largest internet shutdown ever observed in Iran.”

The semiofficial ISNA news agency reported Sunday that Iran’s Supreme National Security Council ordered a “restriction of access” to the internet nationwide, without elaborating.

The Trump administration so far has had a muted response to the protests amid the impeachment hearings investigating the president. State Department spokeswoman Morgan Ortagus tweeted her condemnation of the internet shutdown.

“Let them speak!” she wrote.

In Dubai, the new U.S. ambassador to the United Arab Emirates told The Associated Press that America was “not advocating regime change. We are going to let the Iranian people decide for themselves their future.”

“They are frustrated. They want freedom,” Ambassador John Rakolta said at the Dubai Airshow. “These developments that you see right now are their own people telling them, ‘We need change and to sit down with the American government.’”
