The wives of two Ukrainian soldiers holed up in a Mariupol steel mill met with Pope Francis on Wednesday, asking him to help arrange evacuation of the troops before Russian soldiers overrun the sprawling plant.

Yuliia Fedusiuk, who met with the pope at the conclusion of his weekly general audience in the Vatican’s St. Peter’s Square, said food and water were running out in the mill, that some soldiers were injured and dead and that the survivors were ready to lay down their arms. But they want to be evacuated to a third country, concerned that they would be tortured and killed if they surrendered to the Russians.

“You are our last hope. We hope you can save their lives,” said Kateryna Prokopenko, who wept as she greeted Francis. “Please don’t let them die.”

The plea came one day after the U.S. House of Representatives passed a package of about $40 billion in urgently needed aid for Ukraine, $7 billion more than President Joe Biden requested from Congress.

“The additional resources included in this bill will allow us to send more weapons, such as artillery, armored vehicles and ammunition, to Ukraine,” press secretary Jen Psaki said in a statement Tuesday night. “And they will help us replenish our stockpile and support U.S. troops on NATO territory.”

The bill now goes to the Senate – and Biden urged passage as soon as possible, saying he has “nearly exhausted” the existing aid money for Ukraine.
