Pope: Blood of Ukrainian massacre victims 'cries out to heaven'

The world is witnessing "ever-more horrendous acts of cruelty done against civilians, unarmed women and children, whose innocent blood cries out to heaven and implores, 'End this war. Silence the weapons. Stop sowing death and destruction,'" he said.

Videos and photographs released April 3, after Russian troops retreated from Bucha and other towns, showed dead bodies in the streets and in the yards of homes. Many appeared to have been shot in the head, execution style, and the hands of many of the corpses were bound.

Although Russia dismissed the accusations of war crimes as "fake news," evidence of mass executions sparked outrage, prompting several countries to expel Russian diplomats from their lands and leading to renewed calls for tougher actions against Russia.

After leading pilgrims in a silent prayer for the country, Francis held up a Ukrainian flag that was sent to him "from that tormented city of Bucha."

The pope then invited to the stage several Ukrainian children who recently arrived in Italy and asked the crowd to "greet them and pray together with them."

The children, accompanied by two women, went up to the pope. One young boy held a hand-made poster of the Ukrainian flag, with a smaller Italian flag in the center and outlines of small hands.

The pilgrims present at the audience hall applauded loudly as the pope welcomed the children, with one shouting, "Slava Ukraini" ("Glory to Ukraine")."

Gently rolling up the Ukrainian flag, the pope reverently kissed it before handing out chocolate Easter eggs to the children, prompting one of the women, holding a baby in her arms, to wipe away tears from her eyes.

"These children were forced to flee and come to a foreign land. This is one of the fruits of war," Francis said. "Let us not forget them and let us not forget the Ukrainian people."
