'Help is on its way' says Trump to Iranian protestors

US President Donald Trump urged Iranians on Tuesday to keep protesting and said help was on the way, without giving details, as Iran's government tackled the biggest demonstrations in years.

"Iranian Patriots, KEEP PROTESTING - TAKE OVER YOUR INSTITUTIONS!!!... HELP IS ON ITS WAY," Trump said in a post on Truth Social, adding he had canceled all meetings with Iranian officials until the "senseless killing" of protesters stopped.

 The unrest, sparked by dire economic conditions, has posed the biggest internal challenge to Iran's rulers for at least three years and has come at a time of intensifying international pressure after Israeli and US strikes last year.

Tehran has accused the US president of encouraging political destabilisation, inciting violence, and threatening the country’s sovereignty, territorial integrity, and national security, Iran's UN Ambassador Amir Saeid Iravani wrote to the UN Security Council.

"The United States and the Israeli regime bear direct and undeniable legal responsibility for the resulting loss of innocent civilian lives, particularly among the youth,” he wrote in the letter, which was also sent to UN Secretary-General Antonio Guterres.

He wrote the letter in response to a social media post by Trump earlier on Tuesday.

An Iranian official, speaking to Reuters, said that people he called terrorists were behind the deaths of both protesters and security personnel.

The official, who declined to be named, did not give a breakdown of who had been killed.

On Monday evening, Trump announced 25% import tariffs on products from any country doing business with Iran — a major oil exporter.

Trump has also said more military action is among options he is weighing to punish Iran over the crackdown, saying earlier this month "we are locked and loaded".

Tehran has not yet responded publicly to Trump's announcement of the tariffs, but it was swiftly criticised by China. Iran, already under heavy US sanctions, exports much of its oil to China, with Turkey, Iraq, the United Arab Emirates and India among its other top trading partners.

Russia condemns ‘subversive external interference’
Russia condemned what it described as "subversive external interference" in Iran's internal politics, saying on Tuesday that US threats of new military strikes against the country were "categorically unacceptable."

"Those who plan to use externally inspired unrest as a pretext for repeating the aggression against Iran committed in June 2025 must be aware of the disastrous consequences of such actions for the situation in the Middle East and global international security," the Russian Foreign Ministry said in a statement.

Despite the protests, which come at a particularly vulnerable moment for authorities, given the scale of economic problems, and years of external pressure, there are as yet no signs of fracture in the security elite that could bring an end to the system in power since the 1979 Revolution.

However, underscoring the international uncertainty over what comes next in Iran, which has been one of the dominant powers across the Middle East for decades, German Chancellor Friedrich Merz said he believed the government would fall.

"I assume that we are now witnessing the final days and weeks of this regime," he said, adding that if it had to maintain power through violence, "it is effectively at its end".

He did not expand on whether this forecast was based on intelligence or other assessments.

Iranian Foreign Minister Abbas Araqchi dismissed Merz's criticisms, accusing Berlin of double standards and saying he had "obliterated any shred of credibility".
