 Russian army has several problems in Ukraine's south. United Kingdom Defence Intelligence has reported that intense fighting is continuing on two sectors of the front, including an area near Orykiv city in Saparizia Oblast, Ukraine's south and in the vicinity of Velika Novosilka in Donetsk Oblast. Across the south, common problems for Russian commanders are highly likely to include shortage of artillery ammunition, a lack of reserves and problems securing the flanks of units in the defence. Defence Intelligence said UK Defence Intelligence reported that Ukrainian troops are advancing toward the positions of the Russian 58th Combined Arms Army near Orykiv. Russian soldiers here are exhausted after over eight weeks of intense fighting. To the south of Velika Novosilka, occupation units formed from the Russian Eastern and Southern military districts are holding the defence. UK Defence Intelligence believes that this creates problems with the coordination of the Russian soldiers' actions. UK Intelligence said units of the Russian 5th Combined Arms Army are probably under certain pressure and want to be rotated from the combat zone. Yuri Sak, an adviser to Ukraine's defence minister, said the situation was very dynamic in the south. The Ukrainian armed forces are gradually but steadily continuing the offensive operations which began weeks ago. We are destroying the defence potential of the enemy, he said, stressing that we have not committed our main forces yet.
