Russia has fiercely criticised the US for convening the UN Security Council over protests in Iran.
Russia's envoy Vassily Nebenzia said involving the council in an "internal affair" damaged the top UN body.
Minutes earlier, US Ambassador Nikki Haley praised the protests as a "powerful exhibition of brave people".
Iran's ambassador said the US was abusing its power as a permanent member of the council. At least 21 people have been killed in the protests.
They broke out in one Iranian city in late December against the state of the economy and quickly spread to dozens of cities, with slogans chanted against the government and ruling clerics.
On Wednesday, the head of Iran's Revolutionary Guards declared the defeat of what he described as "sedition" in the country.
A number of countries criticised the US for convening the emergency meeting of the Security Council.
The US envoy told the council that Washington stood "unapologetically with those in Iran who seek freedom for themselves, prosperity for their families and dignity for their nation".
Iranian officials have blamed the demonstrations on foreign meddling and at the UN on Friday Mr Khoshroo said Tehran had "hard evidence" that they were "very clearly directed from abroad".
Ms Haley earlier said that "no dishonest attempt to call the protestors puppets of foreign powers" would deter the US from speaking out.
On Friday, tens of thousands of government supporters again took to the streets across Iran, state TV reported, reports BBC.
