Iran signaled Friday that security forces would crack down on vandalising protesters, directly challenging U.S. President Donald Trump’s pledge to support those peacefully demonstrating as the death toll rose to at least 62.

Supreme Leader Ayatollah Ali Khamenei dismissed Trump as having hands “stained with the blood of Iranians” as supporters shouted “Death to America!” in footage aired by Iranian state television. State media later repeatedly referred to demonstrators as “terrorists,” setting the stage for a violent crackdown like those that followed other nationwide protests in recent years.

Protesters are “ruining their own streets … in order to please the president of the United States,” the 86-year-old Khamenei said to a crowd at his compound in Tehran. “Because he said that he would come to their aid. He should pay attention to the state of his own country instead.”

Iran’s judiciary chief Gholamhossein Mohseni-Ejei separately vowed that punishment for protesters “will be decisive, maximum and without any legal leniency.”

There was no immediate response from Washington, though Trump has repeated his pledge to strike Iran if protesters are killed, a threat that’s taken on greater significance after the U.S. military raid that seized Venezuela’s Nicolás Maduro.
