In a video address posted early Tuesday, Zelensky again called for an investigation into Russian wartime conduct, alleging that the Kremlin’s soldiers did “things that the locals had not seen even during the Nazi occupation 80 years ago.” His foreign minister said at a briefing Monday that the humanitarian situation in the devastated port city of Mariupol was “much worse.” President Biden again said war crimes had taken place in Ukraine and vowed to hold Russian President Vladimir Putin accountable.
As the Russian invasion grinds on, White House national security adviser Jake Sullivan told reporters Monday that the Kremlin was moving its military focus to Ukraine’s south and east. The next stage of the conflict is likely to be “protracted,” and Russia will continue to use brutal tactics, he warned.

In Mykolaiv, Russia continues a pattern: Shelling hospitals
Return to menuMYKOLAIV, Ukraine — Mothers with newborn babies, a woman with a heart condition and elderly people who couldn’t walk on their own hurriedly evacuated to the basement at a Mykolaiv hospital on Sunday night as the booming thuds of artillery drew closer.
They made it down to shelter just in time. Five minutes after patients and staff had crowded into the cramped underground hallway, a suspected cluster munition landed right next to the building. The blast shattered nearly all of the windows.
It made for an eventful first night for Bohdan, who was born in the makeshift bomb shelter after his mother, Vitalina, and others from the maternity ward made the most harrowing journey to safety, from the hospital’s top floor.
“The Russians are animals; there’s no other explanation,” said Bohdan’s grandmother Vlada.
