TEHRAN, Iran — Iran’s state TV on Saturday showed government supporters rallying a day after the foreign minister said a U.S. move to call an emergency U.N. Security Council meeting to discuss anti-government protests was another Trump administration “blunder.”

The state broadcaster showed pro-government rallies in several cities, starting with Amol, in the northern province of Mazandaram, with hundreds of people waving the Iranian flag and chanting slogans against the U.S. and Israel.

State TV described the rally as a “response to rioters and supporters of the riots.”

Other pro-government demonstrations were held in Shahin Dezh, in West Azarbaijan province bordering Turkey; the city of Semnan, in the northern Semnan Province; and Shadegan, in the southern Khouzestan Province near Iraq.

The rallies are meant to be a show of force against anti-government protests that broke out in Mashhad, Iran’s second largest city, on Dec. 28 and have since spread to several other cities and towns. The protests were sparked by a hike in food prices amid soaring unemployment. Some demonstrators have called for the government’s overthrow.

At least 21 people have been killed and hundreds have been arrested. Large pro-government rallies have been held in response, and officials have blamed the anti-government unrest on foreign meddling.

Lawmaker Mahmoud Sadeghi said that around 90 university students– 58 of them in the capital Tehran– have been detained since protests broke out, the semi-official ILNA news agency reported Saturday. Sadeghi said the whereabouts and circumstances of around 10 of those students is unclear, meaning it’s not known which security body arrested them, where they are being held or what charges they face.

Some of those detained, he said, had not participated in protests and for unclear reasons were arrested at home.

On Saturday, Iranians could access the photo-sharing site Instagram again after it was blocked for the past week. The government has suspended access to the messaging app Telegram, which was being used to publicize the protests. Twitter and Facebook were already banned.
