U.S. Ambassador to the United Nations Nikki Haley on Tuesday called the UN to take concrete steps to support Iranians, after anti-government protests erupted over the weekend.

“The UN must speak out,” Haley told reporters in New York City.

Haley called for the United Nations Security Council to hold an emergency session on the protests, which have featured anti-government chants and violent reprisals from the regime. Haley also wants to hear a condemnation from the UN Human Rights Council, a body she has accused of bias against Israel.

“The people of Iran are crying out for freedom,” Haley said. “All freedom-loving people must stand with their cause. The international community made the mistake of failing to do that in 2009. We must not make that mistake again.”

That was a shot at former President Barack Obama, who declined to support the so-called Green Revolution. That frustrated Iran hawks in the United States and Israel, who believe that he neglected the uprising in anticipation of a plan to negotiate a nuclear deal with the Iranians.

“The Obama administration’s lack of support for the Green Revolution was part of a pattern in which it did not hold Iran accountable for any provocation,” former Israeli ambassador to the United States Michael Oren told the Jerusalem Post. “It would seem it was part of a general approach that began in Obama’s first week in office in 2009 of wanting to reach a [nuclear] deal with Iran at pretty much any cost.”

Haley denied that the United States orchestrated the current protests.

“That's complete nonsense,” she said. “The demonstrations are completely spontaneous. They are virtually in every city in Iran. This is the precise picture of a long-oppressed people rising up against their dictators.”
