President Donald Trump tweeted a message of support to Iranian anti-government protesters on Saturday, Jan. 11, as demonstrators erupted the streets of Tehran following the government’s admission that it unintentionally shot down a Ukrainian passenger plane.

Protesters were heard chanting for the Revolutionary Guards to “let go of the country” and calling for the resignation of Supreme Leader Ayatollah Ali Khamenei. They also mentioned the deceased Gen. Qassem Soleimani, shouting that he  “was a murderer, his Leader is also a murderer!”

President Trump weighed in on the protests, saying that his administration would continue to stand with them in solidarity.

“To the brave, long-suffering people of Iran: I’ve stood with you since the beginning of my Presidency, and my Administration will continue to stand with you. We are following your protests closely, and are inspired by your courage,” the president wrote.

The president also called on the Iranian government to allow human rights advocates to monitor the protests and warned against any oppressive government action.

Secretary of State Mike Pompeo earlier in the day voiced his support to the demonstrators, saying, “The voice of the Iranian people is clear. They are fed up with the regime’s lies, corruption, ineptitude, and brutality of the IRGC under @khamenei_ir’s kleptocracy. We stand with the Iranian people who deserve a better future.”

Ukraine International Airlines Flight 752 was shot down Wednesday shortly after leaving Tehran’s international airport by an Iranian surface-to-air missile. All 176 people on board, including Ukrainians, Iranians, and Canadians, were killed. Gen. Amir Ali Hajizadeh, head of the aerospace division of Iran’s Revolutinary Guard accepted “full responsibility” for the downing.

Ukrainian President Volodymyr Zelenskiy took to social media to make statements following Iran’s admission.

“We expect Iran to assure its readiness for a full and open investigation, to bring those responsible to justice, to return the bodies of the victims, to pay compensation, and to make official apologies through diplomatic channels,” Zelenskiy said in a Facebook post. “We hope that the investigation will continue without artificial delays and obstacles.”
