The bulk of Russian forces are now only 18.6 miles (30 kilometers) from the center of Kyiv, the British Ministry of Defence said Saturday.
It also warned Russia that casualties are “likely to be heavy and greater than anticipated or acknowledged by the Kremlin.”
According to the latest intelligence update from the ministry, "Russia has yet to gain control of the airspace over Ukraine greatly reducing the effectiveness of the Russian Air Force."
It said that "Ukrainian Armed Forces continue to put up staunch resistance across the country."
