Russia has signaled it may dial back its war aims to focus on eastern Ukraine after failing to break the nation's resistance in a month of fighting and attacks on civilians, including up to 300 feared killed in the bombing of a theatre.
The possible shift came ahead of a planned meeting by US President Joe Biden with Ukrainian refugees in Poland and talks with his Polish counterpart Andrzej Duda in Warsaw before he gives a speech on the "brutal war", the White House said.
