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

Mikhail Mizintsev, head of the Russian National Defense Control Center, claimed that about 347,000 Ukrainians have evacuated to Russia.

The evacuations occurred "without the participation of the Kyiv authorities," Mizintsev alleged during a press conference Monday, claiming that officials in Kyiv "again have not approved any of the four humanitarian corridors in Russia's direction proposed by the Russian side."

Mizintsev also alleged that Kyiv refuses to conduct humanitarian operations in the besieged city of Mariupol by withdrawing Ukrainian forces from the city.

"At 2 a.m. on March 21, 2022, we received an unsubstantiated refusal to rescue people, and a surrender and laying down arms are out of the question," Mizintsev said, adding that more than 130,000 people remain blockaded in the city.

Mizintsev claimed that in the past 24 hours alone, 16,054 people, including 4,631 children, were evacuated "from dangerous areas of Ukraine and the Luhansk and Donetsk People's Republics" into Russia.

Moscow had had offered safe passage out of Mariupol in return for the city's surrender before 4 a.m. Monday, but Ukraine rejected the offer well before the deadline.

A senior U.S. defense official said at a Monday press briefing that Russian missiles are "failing to launch" as they are fired into Ukraine.

Russia has fired more than 1,100 missiles since the invasion last month, according to U.S. assessments, but there are indications they have been facing problems with the reliability of precision-guided munitions.

Some Russian missiles are "failing to launch, or they're failing to hit the target, or they're failing to explode on contact," the official said.

Additionally, Russian forces are no closer to Kyiv than they were more than a week ago.

"They haven't achieved anything in terms of what we assessed to be their objectives, which was population centers so that they could occupy and take over Ukraine," the official said.

"They are looking for a chance to gain some momentum – not even regain momentum ... because they never really had it. And that's what's so frustrating for them," the official continued.

The official said most credit for the stalled Russian efforts goes to the Ukrainian forces and citizens, and the leadership of President Volodymyr Zelenskyy.

A man who survived multiple Nazi concentration camps was killed in the Russian bombardment of Kharkiv, a city in northeastern Ukraine, on Friday, the country’s Foreign Minister Dmytro Kuleba said.

Kuleba announced the news on Twitter Monday, saying 96-year-old Boris Romantchenko died after a “Russian bomb” hit his home.

“Survived Hitler, murdered by Putin,” Kuleba wrote.

Romantchenko survived four Nazi concentration camps: Bergen-Belsen, Buchenwald, Mittelbau-Dora and Peenemünde.

The Buchenwald Memorial Institute issued a statement saying it is “appalled at the news of Boris Romantschenko’s violent death in the war in Ukraine.”

The institute confirmed a projectile hit the multistory building where Romantchenko lived and ignited his flat.

Secretary of State Antony Blinken condemned Russia while visiting the U.S. Holocaust Museum Monday to tour its Rohingya exhibit.

At the top of his remarks, Blinken discussed the the Russian government’s “unprovoked, brutal war on Ukraine,” including the strike that damaged the Ukrainian Holocaust memorial Babyn Yar.

He also said the Kremlin is falsely claiming to be stopping a genocide in Ukraine, “abusing the term that we reserve for the greatest atrocities, disrespecting every victim of this heinous crime.”

Blinken then pivoted to discuss atrocities elsewhere in the world including China, Ethiopia and Myanmar.

“The day will come when those responsible for these appalling acts will have to answer for them,” he said.
