The Pentagon says the majority of Russian forces that had been around the port city of Mariupol have left and headed north, leaving roughly the equivalent of two battalion tactical groups, or about 2,000 troops.

Pentagon spokesman John Kirby said that even as Russian airstrikes continue to bombard Mariupol, Moscow’s forces are still making only “plodding” and incremental progress as the main fight presses on in the eastern Donbas region.
