Iranian Foreign Minister Abbas Araghchi addressed foreign diplomats in Tehran, asserting that the unrest within the country is now “under total control.” He attributed the violence to Israel and the United States, though he did not provide specific evidence to support these claims.

Araghchi suggested that the escalation of violence was orchestrated to justify potential intervention by the American president. His comments, as reported by Al Jazeera, came even as the network continued to broadcast live from Iran despite the ongoing internet shutdown.

In an apparent gesture towards diplomacy, Araghchi reiterated Iran’s openness to dialogue. The Iranian Foreign Ministry spokesman, Esmail Baghaei, emphasized that any discussions with the US should be grounded in mutual respect and acknowledgement of shared interests, rather than one-sided demands.

On the domestic front, pro-government supporters took to the streets on Monday to demonstrate their allegiance to the ruling theocracy. This show of solidarity followed several days of protests against the leadership of 86-year-old Supreme Leader Ayatollah Ali Khamenei. Iranian state television captured the fervor of the crowd, numbering in the tens of thousands, with chants of “Death to America!” and “Death to Israel!” echoing prominently.

In a stern move, Iran’s attorney general has announced that protesters may face charges that carry the death penalty, signaling a harsh crackdown on dissent.

Meanwhile, President Trump and his national security advisers are reportedly considering a range of actions in response to the situation in Iran. Options on the table include cyberattacks and direct military strikes, potentially involving Israel, according to anonymous sources privy to internal White House discussions.

Trump and his national security team have been weighing a range of potential responses against Iran, including cyberattacks and direct strikes by the US or Israel, according to two people familiar with internal White House discussions who weren’t authorised to comment publicly and spoke on condition of anonymity.

“The military is looking at it, and we’re looking at some very strong options,” Trump told reporters on Air Force One on Sunday night. Asked about Iran’s threats of retaliation, he said: “If they do that, we will hit them at levels that they’ve never been hit before.”

Trump said that his administration was in talks to set up a meeting with Tehran, but cautioned that he may have to act first as reports of the death toll in Iran mount and the government continues to arrest protesters.

“I think they’re tired of being beat up by the United States,” Trump said. “Iran wants to negotiate.”

Iran, through the country’s parliamentary speaker, warned on Sunday that the US military and Israel would be “legitimate targets” if Washington uses force to protect demonstrators.

More than 10,600 people also have been detained over the two weeks of protests, said the US-based Human Rights Activists News Agency, which has been accurate in previous unrest in recent years and gave the death toll. It relies on supporters in Iran crosschecking information. It said 503 of the dead were protesters and 69 were security force members.

With the internet down in Iran and phone lines cut off, gauging the demonstrations from abroad has grown more difficult. The Associated Press has been unable to independently assess the toll. Iran’s government hasn’t offered overall casualty figures.

Those abroad fear the information blackout is emboldening hard-liners within Iran’s security services to launch a violent crackdown. Protesters flooded Tehran’s streets and its second-largest city on Saturday night into Sunday morning. Online videos purported to show more demonstrations on Sunday night into Monday, with a Tehran official acknowledging them in state media.

At 2pm on Monday (9.30pm AEDT), Iranian state television showed images of demonstrators thronging Tehran toward Enghelab Square, or “Islamic Revolution” Square in the capital. It had been airing statements all morning from Iranian government, security and religious leaders to attend the demonstration.

It called the rally an “Iranian uprising against American-Zionist terrorism”, without addressing the underlying anger in the country over the nation’s ailing economy. State television aired images of such demonstrations around the country, trying to signal it had overcome the protests.

Fear pervades Iran’s capital

In Tehran, a witness told the AP that the streets were empty at the sunset call to prayers each night. By the Isha, or nighttime prayer, the streets are deserted.

Part of that stems from the fear of getting caught in the crackdown. Police sent the public a text message that warned: “Given the presence of terrorist groups and armed individuals in some gatherings last night and their plans to cause death, and the firm decision to not tolerate any appeasement and to deal decisively with the rioters, families are strongly advised to take care of their youth and teenagers.”

Another text, which claimed to come from the intelligence arm of the paramilitary Revolutionary Guard, also directly warned people not to take part in demonstrations.

The witness spoke on condition of anonymity due to the ongoing crackdown.

The demonstrations began on December 28 over the collapse of the Iranian rial currency, which trades at more than 1.4 million to $US1, as Iran’s economy is squeezed by international sanctions in part levied over its nuclear program. The protests intensified and grew into calls directly challenging Iran’s theocracy.

Video shows corpses outside capital

Meanwhile, video circulating online purports to show dozens of bodies in a morgue on the outskirts of Iran’s capital.

People with knowledge of the facility and the US-based Human Rights Activists News Agency said on Monday that the video shows the Kahrizak Forensic Medicine Centre.

In the footage, people are seen walking by dozens of bodies in bags laid out in a large room, attempting to identify those there. In some cases, bodies can be seen lying outside on blue tarps. A large truck can be seen in part of the footage.
