Russia continues to invade Ukraine. Russian troops launched a full-scale invasion on February 24, approaching Ukraine’s capital Kyiv and the second city of Kharkov, and it seems that some urban warfare is taking place. According to the US Department of Defense, Russian troops have deployed 190,000 troops in areas such as the border with Ukraine. Initially, about half of these were invested, but now it is said that the number of personnel has been increased to two-thirds. There are also reports that the Russian army’s advance speed is slowing due to resistance by the Ukrainian army.
