Live updates: More US soldiers deploy to support NATO allies

As of Thursday the U.N. World Health Organization has verified 26 attacks on health facilities, health workers and ambulances, including the bombing of the Mariupol maternity hospital, which caused 12 deaths and 34 injuries, DiCarlo said.

All alleged violations of international humanitarian law must be investigated and those found responsible must be held accountable, she said.

DiCarlo stressed that “the need for negotiations to stop the war in Ukraine could not be more urgent.”

Footage recorded on the outskirts of Kyiv by Radio Free Europe on Wednesday shows Ukrainian soldiers with rifles and rocket-propelled grenade launchers slung over their shoulders traversing snow-dusted fields and woods and expressing disdain toward the Russians.

One unidentified soldier called their adversaries “orcs,” a reference to the monstrous and malevolent foot soldiers in the “Lord of the Rings” series.

Another soldier said they planned to kill all their enemies over the bombing of Mariupol.

“We’ll multiply them by zero,” the unidentified soldier said.

Gunfire and explosions erupt during the 3-minute, 30-second clip. At one point in the woods, shots split the air near the group, and soldiers drop to their stomachs in an instant and return fire. The assailants are not visible in the clip, but the crack-crack-crack from the gunfire exchange carries on for 15 seconds in one part of the clip.
