Russia-Ukraine updates: US sanctions Russian military shipbuilder, diamond miner

Ukrainian President Volodymyr Zelenskyy updated the status of negotiations with Russia in his latest address Monday, saying the latest talks went "pretty good" and will continue tomorrow.

Zelenskyy also addressed Russian troops, telling them they would be treated "decently" should they surrender.

"On behalf of the Ukrainian people, I give you a chance -- chance to survive," Zelenskyy said. "You surrender to our forces, we will treat you the way people are supposed to be treated. As people, decently."

Zelenskyy also thanked the producer at a Russian state news channel who appeared on camera behind an anchor and held up an anti-war sign. She was later arrested.

"I am grateful to those Russians who do not stop trying to convey the truth," he said. "To those who fight disinformation and tell the truth, real facts to their friends and loved ones. And personally to the woman who entered the studio of Channel One with a poster against the war."

Marie Yovanovitch, former U.S. ambassador to Ukraine, doubted Russia’s ability to win the war it started, "because the Ukrainian people will continue to resist."

"Ukrainians are never going to turn back to Russia at this point -- never," she told ABC News. "Not after he has invaded them and destroyed their families and destroyed their livelihoods and destroyed their homes. It is appalling what he has done, all in the name of allegedly protecting people in Ukraine. "

While Yovanovitch said she does not believe a ceasefire is currently on Russian President Vladimir Putin's agenda, "It’s important to keep the lines of communication open."

"It's important to keep on talking, at least hopefully to get humanitarian corridors set up so that people can, you know, can leave cities that are no longer habitable because of the barbaric aggressiveness of Russia," said Yovanovitch, who served as ambassador to Ukraine under Presidents Barack Obama and Donald Trump, between 2016 and 2019.

Yovanovitch also said she believes that Trump was dismissive of Ukraine during his presidency, adding that his praise of Putin "emboldened" the Russian leader.

"There's no question that President Trump's actions and his statements presumably emboldened Putin, and I think that Putin was getting what he needed from President Trump in terms of while our official policy was very strong with regard to supporting Ukraine," she said.

The United Nations Office for the Coordination of Humanitarian Affairs has allocated $40 million "to ramp up aid agencies' efforts to reach the most vulnerable people," it announced in a press release Monday.

"These funds are critical to get operations off the ground immediately," U.N. OCHA chief Martin Griffiths said in a statement. "In the early days of our response, fast and flexible funding can make all the difference."

The U.N. is also deploying staff to get food and medicines closer to those in need, according to the release.

Griffiths described Mariupol, the eastern city being heavily bombed by Russia with hundreds of thousands of civilians trapped inside, as the "center of hell" in an interview with CNN on Monday.

"The most important priority … is to get civilians out," Griffiths said.

The International Court of Justice will soon issue a ruling on allegations brought against Russia by Ukraine.

Ukraine had launched a case against Russia at the United Nations' highest court, located in Hague, The Netherlands, accusing Moscow of planning genocide.

Ukraine also asked the court to intervene to halt the invasion and to order Russia to pay reparations.

The court will deliver the ruling at 11 a.m. EST on Wednesday, the U.N. announced in a press release.
