The UN charter empowers to the council to "investigate any dispute, or any situation which might lead to global friction", and the USA wasn't alone in thinking the Iranian protests qualified.
US President weighed in on protests in Saturday, warning that the country's people want change and 'oppressive regimes can not endure forever'.
Observing that the Council's primary responsibility is maintaining global peace and security, Wu Haito of China said that it should not be the venue for discussing the human rights situation of any country.
Ending the nuclear accord "would be a major setback for the entire global community", French envoy Francois Delattre said, adding that "the agreement is one of the cornerstones of stability in the Middle East as a whole".
Russian Federation challenged right at the outset the jurisdiction of the UNSC over a situation that it called a strictly domestic affair of Iran that would be best left for the Iranian authorities to deal with.
But Iran's Ambassador to the UN Gholamali Khoshroo criticized the council for taking up a matter his country considers "purely domestic", and called it bullying by the United States.
Furthermore, U.S. -allied France and the United Kingdom defended the the Iran nuclear deal, known as the Joint Comprehensive Plan of Action on Iran's nuclear program, and noted Iran's compliance.

"It's another attempt [at bullying] by the US, which has lost authority and credibility in the eyes of the whole world", said Khoshroo. Their comments come one week before Trump must decide whether to continue waiving sanctions which, if implemented, could unravel the deal, known as the Joint Comprehensive Plan of Action.
"However worrying the events of the last few days in Iran may be, they do not constitute per se a threat to worldwide peace and security", Ambassador Francois Delattre said.
He said his government has "hard evidence" recent protests in Iran were very clearly directed from overseas.
Trump's administration has denied having any hand in the demonstrations, saying they arose completely spontaneously.
Donald Trump has tweeted his support for the anti-government protesters, warning Iran that the "world is watching".
"The UNSC rebuffed the US' naked attempt to hijack its mandate". Up to 42,000 people took part in the protests, according to Interior Minister Abdolreza Rahmani Fazli, who has said the clerically overseen government exhibited "tolerance" toward the demonstrations.
China also described the meeting as meddling in Iran's affairs. Due to the Trump administration, it's not only watching, it's also acting. The days of pro-government rallies drew crowds in the tens of thousands.More news: Brad Pitt bids $120K to watch 'Game of Thrones' with Emilia Clarke
