The Pentagon said some Russian forces have crossed from the Kharkiv region back into Russia.
“We’ve seen a number of Russian forces, especially in the northeast, in the Kharkiv region, cross over the border back into Russia as they’ve retreated from the Ukrainian counter-offensive,” Pentagon press secretary Brig. Gen. Pat Ryder told reporters during a briefing Tuesday.
But Russian forces still “do exist en masse in Ukraine,” Ryder said.
The US was not surprised that Ukraine forces “pushed as quickly as they have” in the counteroffensive, Ryder said, but based on reports that the Pentagon has seen “on the Russian military response, it was probably the Russians” who were surprised by the push.
