Russia’s abduction and deportation of Ukraine’s children since its invasion of the country was so well-documented and terrifying that when Russian forces prepared to withdraw from the southern city of Kherson last fall, doctors at a hospital there hurriedly hid babies and falsified their records.

When Russian soldiers arrived, the staff at Kherson Regional Hospital said the infants were too critically ill to move, Olha Pilyarska, head of its neonatal anesthesiology department, recalled in an interview Saturday.

"They put lung ventilation devices near all the children,” she said.
