US Ambassador to the UN Nikki Haley said that the US could call for emergency sessions at the UN Security Council and Human Rights Council on the mass protests against the Ayatollahs' regime in Iran.

“The U.N. must speak out,” Haley said at a press conference. “In the days ahead, we will be calling for an emergency session both here in New York and at the Human Rights Council in Geneva. We must not be silent. The people of Iran are crying out for freedom.”

The protests against the ruling regime in Iran entered their sixth day Tuesday. Since last Thursday, thousands of Iranian civilians have taken to the streets to protest against President Hassan Rouhani’s government and the country’s supreme leader, Ayatollah Ali Khamenei.

The uprising, the largest since a series of mass protests in 2009, began in the city of Mashhad, when demonstrators denounced President Rouhani over the failure to reduce the country’s high unemployment rates.

Videos on Nazar's Telegram channel showed people in Mashhad, an important religious center in the northeast of Iran, chanting "Death to Rouhani".

They also showed chants of "Death to the dictator" and "Not Gaza, not Lebanon, my life for Iran", a reference to anger in some circles that the government is focusing on the wider region rather than improving conditions at home.

According to some reports, as many as 13 people were killed by Iranian security forces over the weekend in protests across the country. The Associated Pressconfirmed 12 of the 13 reported deaths.

The Iranian government blocked some social media outlets and popular instant messaging systems, calling the move a "temporary" limitation intended to prevent protesters from organizing mass demonstrations.

Both President Donald Trump and Israeli Prime Minister Binyamin Netanyahu have expressed their support for protesters, and called on other world leaders to back the demonstrations.
