Trump's latest tweet follows a series of other missives over the New-Year period in which he labelled Iran the "Number One State of Sponsored Terror".
"Iran's security and stability depend on its own people, who - unlike the peoples of of Trumps regional "bffs" - have the right to vote and to protest", Zarif tweeted.
"All of the money that President Obama so foolishly gave them went into terrorism and into their 'pockets, '" he continued, referring to the Iran nuclear deal. The Iranian people are fed up with the corruption and human rights violations.
While there's no evidence to suggest Iran used that money directly to fund terrorism, the U.S. State Department lists Iran as a state sponsor of terrorism.
"Do not get excited", Parliament director for global affairs Hossein Amir-Abdollahian wrote in a tweet directed at Mr. Trump.
"We call on the Iranian authorities to uphold and respect democratic and human rights", said a statement by Global Affairs Canada. "The citizens of Iran have paid a heavy price for the violence and extremism of their leaders, and the Iranian people long to reclaim their country's proud history, its culture, its civilization and its cooperation with its neighbors".
Iran saw another day of large pro-regime rallies on Thursday, after authorities declared the end of deadly unrest and turned attention to addressing the economic concerns that fuelled protests.
Following two weeks of large demonstrations in Tehran by people who had lost their savings from massive bank and credit institution fraud, they are demanding justice and shouting slogans against President Rouhani and against the Supreme Leader, chanting "Death to Khamenei!" But the regime should be given no excuse to claim (as supreme leader Ayatollah Ali Khamenei already has) that foreign powers are behind the demonstrations, which clearly are the result of myriad domestic frustrations, not foreign intervention.
"What these protests are about are the rights of the Iranian people, not some foreign fantasy of Mr. (Ayatollah Ali) Khamenei", Peek said. The National Security Council has chose to block social media and messaging apps to restrict the flow of information.
Working-class Iranians and others, meanwhile, are increasingly unhappy with a stagnant economy despite the lifting of global sanctions under the nuclear accord with world powers.
And the third thing (which may account for the second) is that the majority of protesters this time are not middle-class students and professionals but lower-class people with very little to lose. But she said the administration is keeping "our options open" as far as sanctions against Iran are concerned.
He accused what he described as Iran's enemies of fomenting the disturbances, a clear reference to the United States, Israel and Saudi Arabia, and he said Iran's courage and faith would overcome such efforts.
There was a brief period when it appeared that President Barack Obama was going to weigh in on the side of the protesters, but in the end, he held back, a decision that was widely criticized in the aftermath as a missed opportunity to back those calling for a return to democracy in Iran.
