Pro-government demonstrators staged rallies across the country Wednesday, after days of protests against the government and economic problems.

Iranian state television showed video of crowds waving Iranian flags and chanting in support of Supreme Leader Ayatollah Ali Khamenei.

Khamenei has blamed other governments for driving the anti-government protests that began last week and have left at least 21 people dead.

“In recent days, enemies of Iran used different tools, including cash, weapons, politics and intelligence apparatus to create troubles for the Islamic Republic.” Khamenei said in a televised statement Tuesday. He added that he would address the nation about the protests “when the time is right.”

Ali Shamkhani, secretary of Iran’s Supreme National Security Council, accused the United States, Britain and Saudi Arabia of being behind the protests.

The United States is calling for the United Nations Security Council to hold an emergency session to discuss the Iranian protests. U.S. Ambassador to the U.N. Nikki Haley said the Iranian people “are crying out for freedom.”

U.S. National Security Adviser H.R. McMaster made similar comments in an interview Tuesday with VOA. He also told VOA the Iranian government has to be held accountable for its actions.
