STORY: Kateryna Prokopenko, 27, and Yuliya Fedosiuk, 29, crying as they spoke to the pope for about five minutes at the end of his general audience in St. Peter's Square, telling him he was 'their last hope' to save their husbands' lives.
"You are our last hope, I hope you can save their lives, please don't let them die," Prokopenko could be heard telling the pope on a video released by the Vatican.
Mariupol, a port on the Sea of Azov, has endured the most destructive fighting of the war in Ukraine. Kyiv says it is likely that tens of thousands of people have been killed there since Russia's invasion on Feb. 24, and the Azovstal steel plant is the last part of the city still held by Ukrainian fighters.
The pope said he would do everything possible and would pray for them.
