A total of 21 people have died and hundreds have been arrested since December 28 as protests over economic woes turned against the Iranian regime, with attacks on government buildings and police stations.
Ambassador Vassily Nebenzia said the demonstrations are a domestic matter, not an worldwide security issue warranting the attention of the U.N.'s most powerful body.

U.S. Ambassador Nikki Haley has praised the anti-government demonstrators as courageous freedom-seekers who need the world's support.

But Russia's deputy foreign minister, Sergei Ryabkov, has portrayed Friday's Security Council meeting as an American attempt to violate Iran's sovereignty.
The United States called the meeting despite fierce criticism from Russian Federation, which accused Washington of interfering in Iran's internal affairs.
