Invading Russian forces have made a small amount ofgains in Ukraine, particularly in the north part of the Donbas, U.S. Department of Defense spokesperson John Kirby said during a press briefing on May 5.
"In the Donbas region we would still assess that the Ukrainians are putting up a very stiff resistance and that the Russians have not made the progress that we believe they expected to make by this point," Kirby said.
"That's not to say they haven't made any progress."
Earlier the head of the Ukrainian army, Lieutenant General Valeriy Zaluzhny, said that Ukraine's defense forces had launched a counteroffensive in the areas of Kharkiv and Izyum.
According to Ukraine's General Staff, Russia has lost about 24,700 of its soldiers since the beginning of its full-scale invasion of Ukraine.
