WASHINGTON, May 1 (Reuters) - The White House on Monday estimated that Russia's military has suffered 100,000 casualties in the last five months in fighting against Ukraine in the Bakhmut region. "Russia's attempt at an offensive in the Donbas largely through Bakhmut has failed," Kirby said. He said the Russians have made some incremental gains in Bakhmut but that this has come at a "terrible, terrible cost" and that Ukraine's defenses in the region remain strong. "It's really stunning, these numbers," Kirby added, saying the total is three times the number of American casualties in the Guadalcanal campaign in World War Two. Kirby said another U.S. weapons package for Ukraine would be announced soon.
