Comments Marianna made in her interview with Denis were cherry-picked by Russian officials to claim soldiers forced Marianna and the other pregnant women to act as human shields.
But Marianna told me there were no Ukrainian military stationed in the building where she was. She says she saw Ukrainian soldiers in the oncology unit in the building opposite the maternity unit. It's unclear whether they were based there or not.
Nevertheless, Marianna's interview with Denis Seleznev was used by the Kremlin to suggest further falsehoods.
Russian officials have seized on her comments that she doesn't believe the explosions at the hospital were caused by an airstrike, implying that the damage was Ukrainian shelling.
"The typical sound a plane makes when it flies overhead is impossible to miss," Marianna tells me, saying that she did not hear one.
But here she is mistaken. The AP journalists documented evidence it was an airstrike, including video where a plane can be heard. At the scene both a soldier and a police officer say the attack was an airstrike.
Also visible in photos is a huge crater which munition experts say could only have been caused by an airstrike.
"I personally did not see this crater, but I saw the video of it," Marianna says. "In reality I can't blame anyone - because I didn't see with my own eyes where for certain [the explosions] came from."
