The Russian army has lost about 20 thousand people since the beginning of the invasion.. The Guardian writes about this, citing a source in high-ranking circles.. Previous Western estimates of Russian casualties in the second half of May were 15,000 dead..

Russian troops are losing a particularly large amount of manpower and military equipment in the current battles in the west of the Lugansk region - in the area of \u200b\u200b\\u200b\\u200bthe cities of Severodonetsk and Lysichansk, where they managed to achieve some success and move forward, the source says..

Ukrainian command estimates Russian losses at 31,000 killed. Similarly, the size of Ukrainian losses is not known..

Ukrainian Defense Minister Aleksey Reznikov said that now the country's armed forces are losing about 100 fighters killed and up to 500 wounded every day.. It is not possible to check the data on losses in combat conditions.

The Guardian source notes that soon both sides will face the problem of physical and psychological fatigue of the troops.. In his opinion, the Russians have more significant reserves of manpower, but this can be compensated by the higher morale of the Ukrainian military..
