"For these crimes, the Russian command will surely see military tribunal," Shmyhal said at a press conference Saturday. "The enemy will surely be punished for killing Ukrainian children," Shmyhal said. "The Russian government doesn't understand they are not fighting only with the government, in fact they are fighting against the entire Ukrainian people."
Russian troops are facing a determined and highly-motivated Ukrainian resistance, resulting in significantly slower progress than Kremlin military planners had first anticipated, according to an assessment issued by Britain's Ministry of Defense late Saturday.
Russia is also facing unexpected difficulties supplying its forces, and is experiencing heavier losses in personnel, armor and aircraft than expected, two senior United States officials with direct knowledge told.
Ukrainian Maj. Gen. Borys Kremenetsky told reporters Saturday that Ukraine had captured around 200 Russian soldiers, some of whom were just 19 years old. They were not trained at all and were badly equipped, he said.
Russia has yet to establish air supremacy over Ukraine, one US official said, as the Ukrainian Air Force and air defense systems fight for control of the airspace. Without uncontested control of the skies, it becomes more difficult for an army on the move to see and strike targets from the air.
