Pregnant Mother and Baby Photographed After Hospital Bombing by Russia Did Not Survive: AP

Captured in one of the most visceral and painful photographs yet taken of the carnage and human suffering underway in Ukraine, a pregnant woman and her unborn child died from the injuries suffered during a Russian bombing of a maternity hospital in the city of Mariupal last week.

According to the Associated Press, whose photographer Evgeniy Maloletka took the picture "epitomizing the horror of an attack on humanity's most innocent" outside the bombed hospital on March 9, the mother and her baby died shortly after the attack despite efforts by paramedics on the scene and doctors at a nearby hospital to save them.

Surgeon Timur Marin found the woman's pelvis crushed and hip detached. Medics delivered the baby via cesarean section, but it showed "no signs of life," the surgeon said.

Then, they focused on the mother.

"More than 30 minutes of resuscitation of the mother didn't produce results," Marin said Saturday.

"Both died."

In the chaos after Wednesday's airstrike, medics didn't have time to get the woman's name before her husband and father came to take away her body. At least someone came to retrieve her, they said--so she didn't end up in the mass graves being dug for many of Mariupol's growing number of dead.

Last Wednesday's bombing of the hospital was condemned worldwide as a possible war crime, an attack that coincided with increasingly aggressive targeting by Russian forces on civilian infrastructure that prevented thousands of individuals and families from fleeing areas under assault.

The United Nations says nearly 600 civilians have died since the Russian invasion began, though the international body concedes the actual number is certainly much higher.

In a joint statement on Sunday, UNICEF executive director Catherine Russell, UNFPA executive director Dr. Natalia Kanem, and WHO director general Dr. Tedros Adhanom Ghebreyesus said there can be no tolerance for military attacks on hospitals or other places of care in Ukraine.

"To attack the most vulnerable--babies, children, pregnant women, and those already suffering from illness and disease, and health workers risking their own lives to save lives--is an act of unconscionable cruelty," the statement read.

According to the U.N. agencies, 31 attacks on health care facilities--including hospitals and ambulances--have been documented since Russia attacked Ukraine last month.

"These horrific attacks are killing and causing serious injuries to patients and health workers, destroying vital health infrastructure, and forcing thousands to forgo accessing health services despite catastrophic needs," the trio wrote in their statement.

Russell, Kanem, and Dr. Tedros concluded by saying, "For the sake of health workers, and for all people in Ukraine who need access to the lifesaving services they provide, attacks on all health care and other civilian infrastructure must stop."

"We call for an immediate ceasefire," they said, "which includes unhindered access so that people in need can access humanitarian assistance. A peaceful resolution to end the war in Ukraine is possible."
