He accused authorities of “squandering of the nation’s wealth to fund terrorism abroad”. Later, he posted two clips of his speech to the UN General Assembly in September in which he took aim at Iran, which Washington has held out as its top adversary in the Middle East. “Oppressive regimes cannot endure forever, and the day will come when the Iranian people will face a choice,” he tweeted, quoting from the speech. The Iranian government shot back at Mr Trump, calling his comments “deceitful” and “opportunistic”. مخاطبان بیبیسی فارسی این تصاویر را از “خیابان طالقانی #ابهر” فرستادهاند. گروهی از مردم در این ویدیو بیلبورد با عکس آقای #خامنهای را به زیر میکشند pic.twitter.com/q5RejFwYV2— BBC Persian (@bbcpersian) December 30, 2017 The demonstrations began on Thursday in the northeastern city of Mashhad, largely over the rising cost of living, but quickly spread around the country and became more explicitly critical of Ayatollah Khamenei and of Hassan Rouhani, Iran’s president. While the security forces showed relative restrain during the first 48 hours of protests, their response hardened on Saturday and authorities reportedly cut off some internet access in Tehran to try to stop the spread of unrest.

Several dozen students at the University of Tehran protested at the campus gates yesterday and chanted “death to the dictator” in apparent reference to Ayatollah Khamenei. Security forces fired tear gas and made arrests and the protesters were eventually replaced by a larger crowd of pro-government students who chanted “death to the seditionists” as they took back control of the gates. Thousands of people also turned out for annual pro-government rallies to mark the defeat of the last major protest movement in 2009.

Mr Trump said in a tweet that the “Iranian government should respect their people’s rights, including right to express themselves. The world is watching!” It was not clear what impact his intervention would have. Mr Trump’s decision to focus worldwide attention on the protests may discourage the Iranian government from using violence. But the protesters may also be sullied by association with Mr Trump, who is widely unpopular in Iran.

The protests are a wildcard in the complicated political balance between Mr Rouhani, a relative moderate who was re-elected this year as president, and his more hardline political rivals.

Some analysts said he might try to turn the demonstrations to his advantage by promising a more aggressive campaign against corruption in response to the demands from people on the streets. “The country is facing serious challenges with unemployment, high prices, corruption, lack of water, social gap, unbalanced distribution of budget,” said Hesamoddin Ashena, his cultural advisor. “People have the right for their voice to be heard.” One of the popular chants has “No Gaza No Lebanon, My Life for Iran”, an expression of frustration money being spent on Iran’s foreign interventions around the Middle East instead of on domestic programmes.
