Presidential aide announces grim toll at the World Economic Forum in Davos, Switzerland as Ukraine’s first lady appeals for support.

More than 9,000 Ukrainian civilians, including 453 children, have been killed since Russia’s invasion 11 months ago, according to a top official.

Ukrainian presidential aide Andriy Yermak announced the grim toll at the World Economic Forum (WEF) in Davos, Switzerland on Tuesday

“We have registered 80,000 crimes committed by Russian invaders. “We will not forgive a single [act of] torture or life taken. Each criminal will be held accountable.”

Yermak reiterated calls for a special international tribunal to try Russia and reparations for the destruction caused by the invasion.

On Monday, the United Nations said more than 7,000 civilians had been killed. It is impossible to verify either figure, but estimates of war dead are often understood to be lower than the reality.

Ukraine’s First Lady Olena Zelenska told attendees that parents are in tears watching doctors try to save their children.
