More than 20,000 Russian soldiers have been killed and more than 80,000 injured in just five months of fighting in Ukraine, an acceleration in already heavy losses for Moscow, US intelligence officials estimate.
Most of the troops were killed in brutal trench warfare for the small eastern city of Bakhmut, which Russia has repeatedly claimed it was on the brink of capturing, White House national security council spokesperson John Kirby said when he revealed the new estimate on Monday.
