In an impassioned overnight address to the U.N. Security Council, Ukrainian President Volodymyr Zelensky accused Russian officials of committing war crimes and concealing their guilt in the war-torn country.

The comments come after more than 300 people are believed to have been tortured and killed in the Kyiv suburb of Bucha. Zelensky went into detail about the atrocities in a video speech that lasted over 16 minutes. He called the massacre in Bucha just one of the many examples of Russian atrocities in the 41 days of its invasion.

"Civilians were crushed by tanks, while sitting in their cars in the middle of the road. ... [Russian forces] cut off limbs, slashed their throats, women were raped and killed in front of their children. Their tongues were pulled out only because ... they did not hear what they wanted to hear from them," said Zelensky.

Russia has rejected allegations and instead claimed that Ukrainian forces "staged" or carried out the war crimes themselves. In response, Zelensky called for thousands of journalists to visit Bucha to see the atrocities firsthand, while satellite images have contradicted Russia's response that the photos were staged.

Zelensky called on Russia to be removed from the Security Council and for "full accountability" for the "most terrible war crimes" since World War II.

The West has sent a wide range of weapons to Ukraine, which has aided in the defense against Russian forces. Zelensky has sought out more complex weaponry, such as missile systems and fighter jets.

Zelensky said that he is “doing everything possible to identify all the Russian military involved in these crimes as soon as possible. Everything to punish them," with help from European Union officials and the International Criminal Court.

The U.S. government recently accused Russia of being responsible for war crimes. President Joe Biden referred to Russian President Vladimir Putin as a “war criminal,” calling his actions “atrocities” and “an outrage to the world.”

Secretary of State Anthony Blinken backed Biden’s sentiments, concurring that “based on the countless accounts and images of destruction and suffering we have all seen, that war crimes had been committed by Putin’s forces in Ukraine.”

Speaking about the recent reports from Bucha, Blinken said the alleged Russian actions were a “deliberate campaign to kill, to torture, to rape."

NATO foreign ministers are set to talk about additional military aid for Ukraine in Brussels on Wednesday. The West is reportedly set to impose another slew of sanctions on Russia.

“The time will come when every Russian will learn the whole truth about who of their fellow citizens killed,” Zelensky added. “Who gave orders? Who turned a blind eye to the murders? We will establish all this. And make it globally known."
