Mass graves and bullet-scarred churches mark the torment of past Russian occupation in the Kyiv suburb of Bucha, where traumatized residents now face a new anguish: a U.S.-led peace proposal that would offer a blanket post-war amnesty for the perpetrators of atrocities.

Polish Prime Minister Donald Tusk said “it would be good to know for sure who is the author of the plan,” as tensions over elements that mirror long-standing Russian demands.

President Volodymyr Zelenskyy said Friday that Ukraine has to confront the possibility of losing its dignity or risking the loss of a key partner as it figures out how to respond to a U.S. peace proposal to end Russia's war with his country.
