President Joe Biden spoke by phone with Ukraine President Volodymyr Zelenskyy for almost an hour Wednesday, one day after Zelenskyy praised Biden for accusing Russian President Vladimir Putin of “genocide.”

Biden said in a statement that he has authorized an additional $800 million in security assistance to Ukraine, including weapons and ammunition.

“The Ukrainian military has used the weapons we are providing to devastating effect,” Biden said. “As Russia prepares to intensify its attack in the Donbas region, the United States will continue to provide Ukraine with the capabilities to defend itself.”

Zelenskyy tweeted about their conversation, saying: “Continued constant dialogue with @POTUS. Assessed Russian war crimes. Discussed additional package of defensive and possible macro-financial aid. Agreed to enhance sanctions.”

Also Wednesday, Treasury Secretary Janet Yellen warned that China and other nations declining to sanction Russia could face future economic fallout for failing to help end Russia’s “heinous war” in Ukraine. “Let’s be clear, the unified coalition of sanctioning countries will not be indifferent to actions that undermine the sanctions,” Yellen said.

‘These are somebody’s children’: Russia asked to retrieve dead soldiers

Authorities in the east-central Ukraine city of Dnipro say they are willing to help return to Russia the bodies of more than 1,500 Russian soldiers now in city morgues.

“We already have four refrigerators full of bodies of Russian soldiers,” Deputy Mayor Mykhailo Lysenko said. “No matter what, these are someone’s children.”

The city’s airport and some infrastructure was destroyed by rocket attacks just days ago. Military analysts say Russia’s new focus on eastern Ukraine could include the city of 1 million people in the Donbas region, where Russian separatists have battled Ukraine troops since 2014.

Russia reloading helicopters, artillery for push into eastern Ukraine

Russia continues shipping additional helicopters, artillery and troops for a renewed push into eastern Ukraine, a senior Defense official said Wednesday. A miles-long Russian convoy remains headed toward the strategic town of Izyum, said the official who spoke on condition of anonymity to describe intelligence assessments. The convoy had been about 35 miles north of Izyum on Tuesday. It’s unclear how much progress has been made toward the town. South of Izyum, the Russians are seeking to improve their movement inside Ukraine, including the building of a temporary bridge.

The Russian focus in eastern Ukraine is consistent with a new offensive in eastern Ukraine after retreating from the country’s north, the official said. Russian airstrikes have concentrated on targets in the eastern Donbas region and the besieged city of Mariopul, the official said.

WHO chief challenges world to worry about black lives, too

The head of the World Health Organization slammed the global community Wednesday for turning a blind eye on crises outside Ukraine. WHO director-general Tedros Adhanom Ghebreyesus questioned whether “the world really gives equal attention to black and white lives,” citing dire issues of war, disease and famine in countries such as Ethiopia, Yemen, Afghanistan and Syria. He said the Horn of Africa are at high risk of famine and many people are “already starving or food insecure and increasingly on the move.”
