The Treasury Department announced sanctions on Wednesday against the top Iranian official overseeing the prosecution of protesters and key military figures who have cracked down on demonstrations in recent months. 

Iran has been roiled by mass protests over the death of Mahsa Amini, a 22-year-old woman who died after being taken into custody by the regime's so-called morality police for allegedly not wearing a hijab. 

The sanctions announced Wednesday include Iranian Prosecutor General Mohammad Jafar Montazeri, who issued a directive in late September for courts to issue harsh sentences to protesters. 

Two Islamic Revolutionary Guard Corps (IRGC) officials and two top officials from Iran's Basij Resistance Forces, a paramilitary force controlled by the IRGC, were also sanctioned.

"We denounce the Iranian regime’s intensifying use of violence against its own people who are advocating for their human rights," Under Secretary of the Treasury for Terrorism and Financial Intelligence Brian Nelson said in a statement. 

Nearly 500 people have been killed since protests began about two months ago and more than 18,000 have been detained by authorities, according to Human Rights Activists in Iran, an organization that has been tracking the protests. 

Two prisoners have already been executed. Majidreza Rahnavard, accused of fatally stabbing two members of a paramilitary force, was publicly hanged from a construction crane earlier this month in Masshad. Another prisoner, Mohsen Shekari, was executed on Dec. 8.

Ukrainian President Volodymyr Zelenskyy made a direct appeal to Republican critics during his Wednesday address to a joint meeting of Congress, telling lawmakers that no country was safe in the face of Russian aggression.

In a speech that won several standing ovations from both sides of the aisle, Zelenskyy predicted the war would hit a turning point next year just as Republicans were set to take control of the U.S. House of Representatives.

"The struggle will define in what world our children and grandchildren will live," said Zelenskyy. "This battle cannot be frozen or postponed, it cannot be ignored hoping that [an] ocean or something else will provide protection."

The Ukrainian president said the world was "too interconnected and interdependent" for the U.S. to "stand aside and at the same time feel safe when such a battle continues."

"Your money is not charity," he said. "It’s an investment in the global security and democracy that we handle in the most responsible way."

Zelensky said that U.S. support was crucial not only for Ukraine's victory, but also to show Russia and China that "no one can succeed in breaking national borders" or committing atrocities. And he made a direct appeal for more U.S. military aid.

"Ukraine never asked that Americans soldiers fight on our land instead of us," said Zelenskyy. "I assure you that Ukrainian soldiers can perfectly operate American tanks and planes themselves."

"More cannons and shells are needed," said the president. "Russia can stop its aggression if it wanted, but you can speed up our victory."

Zelensky's address came as Congress was slated to pass a $1.7 trillion spending bill this week. The bill includes more than $45 billion in additional military and humanitarian aid for Ukraine — boosting the U.S.'s total commitment to the war to over $100 billion if it passes.

Some Republican lawmakers, specifically in the House, have criticized sending more money to Ukraine. They've argued sending more aid without proper accountability metrics in place or a plan for ending the war is improper.

"Most of my constituents do not wish to have their money sent to Ukraine, especially not without oversight or an audit," said Rep. Thomas Massie, R-Ky.

Other House Republicans have also lambasted the notion of spending money on bolstering Ukraine's security while the U.S.-Mexico border faces an immigration crisis.

"I will oppose giving more money to Ukraine while our own southern border remains open to an invasion led by drug cartels," said Rep. Mary Miller, R-Ill.

Zelenskky during Wednesday's address challenged GOP lawmakers to think broader in their view of the world.

"I know that everything depends on us, the Ukrainian Armed Forces, yet so much depends on the world," said Zelenskky. "So much in the world depends on you."
