Washington: US President Donald Trump on Saturday weighed in on protests in Iran for a second straight day, warning that the country's people want change and "oppressive regimes cannot endure forever."

Trump posted on Twitter two clips of his speech to the UN General Assembly in September in which he took aim at the Iranian regime, 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 world is watching!"
Later Saturday, Vice President Mike Pence added his voice, saying: "The time has come for the regime in Tehran to end terrorist activities, corruption, & their disregard for human rights."
White House spokeswoman Sarah Sanders added: "The days of America looking the other way ... are over."
Trump's posts came as several hundred anti-government demonstrators clashed with police at the University of Tehran in a third straight day of protests.
Hundreds of counter-protesters also massed outside the entrance to the university, chanting "Death to the seditionists" in a show of support for the regime.
Videos shared by social media users outside Iran but which could not be independently verified claimed to show thousands marching peacefully against the regime in several cities including Khorramabad, Zanjan and Ahvaz, with chants of "Death to the dictator."
"The entire world understands that the good people of Iran want change, and, other than the vast military power of the United States, that Iran's people are what their leaders fear the most," Trump said, again quoting from the UN speech.
Trump also tweeted in support of the protesters late Friday, prompting Iran's foreign ministry spokesman Bahran Ghasemi to dismiss his remarks as "opportunistic."
Iran is failing at every level despite the terrible deal made with them by the Obama Administration. The great Iranian people have been repressed for many years. They are hungry for food & for freedom. Along with human rights, the wealth of Iran is being looted. TIME FOR CHANGE!— Donald J. Trump (@realDonaldTrump) January 1, 2018
