"It is right and proper - indeed, our responsibility.to assess whether a situation like this could become a threat to worldwide peace and security", British Ambassador Matthew Rycroft said before the meeting.
In the city of Kerman, demonstrators chanted that the "People are living like beggars, the Leader is behaving like a God", and in Khuzestan, protesters reportedly called out "death to Khamenei", Iran's supreme leader.
During an event Friday titled, "The Iran Protests: Implications for the Islamic Republic and Beyond" Reuel Gerecht, a senior FDD fellow who focuses on Iran said, "Rouhani is one of the architects of the national security state [in Iran]". He did not elaborate.
The protests began on December 28 as protests over economic hardship and quickly turned against the regime as a whole. "In 2018, we will not be silent", Haley added.
"We share the worries expressed by Iranian civil society groups over what will happen to the people who have been arrested".
The United States called on the council to demand Iran improve its human rights situation.
Alma Konurbayeva, a spokeswoman for current council president Kazakhstan, confirmed that Friday afternoon's meeting is about Iran.
But countries including France, Bolivia and Russian Federation agreed that the Security Council should not get involved in the Iranian protests.
She called on all of her other colleagues in the Security Council to join her in amplifying the message of the Iranian people. It was unclear Friday morning whether Haley has that level of support. She said the worldwide community must also "do more" to prevent Iran from silencing protesters' messages, particularly by blocking some social media platforms.
"Let Iran deal with its own problems", Nebenzia advised, adding, "The real reason for convening today is not to protect human rights or promote the interests of the Iranian people, but rather a veiled attempt to continue to undermine the Iranian nuclear agreement", cited by the New York Times.
The United States requested the meeting, which lasted for about 2 hours. Something that of course will only see to further anger not only protesters but the government in Tehran too.
He said: "What we need is a regional strategy which consists in finding ways to limit Iran's influence in the Middle East".
Iran is also weighing in to U.N. Security Council members.
Haley said that "in the end, the Iranian people will determine their own destiny", and she reiterated United States support for the protesters.
Nebenzia remarks echoed those of Moscow's Deputy Foreign Minister Sergei Rybakov, who accused the USA of "shamelessly" interfering in the in a "situation that is of purely national concern to Iran".
But Russia and Iran complained that the US was dragging the U.N.'s most powerful body into what they called a domestic matter.
While the USA and its European partners - including the United Kingdom, France and Germany - all fundamentally support the right of Iranian demonstrators to peacefully protest, they disagree in their analysis of where the situation on the ground is headed and over the strategic value of ramping up the rhetoric publicly, sources have told CNN.
