Russia's invasion has displaced half of Ukraine's children.

On a hospital bed in a town close to the border with Poland, a little girl with a long blonde braid and dressed in pink is one of them.

The fragile 10-year-old became so unsettled that her father risked his life to return to their ninth-floor apartment 60 miles (90 kilometers) south of the capital, Kyiv, to rescue her pet hamster, Lola, to comfort her.

"I want peace for all Ukraine," the little girl said, shyly.
