 Ukrainian forces reach Russia's first defence line in Ukraine south. Ukrainian troops continued offensive operations on the Militopol and Burdiansk fronts, reaching the first line of defence of the Russian forces. Serhii Kuzmin, deputy commander for strategic communications of the Tavria operational and strategic group of forces, said this. Ukrainian troops continue offensive operations near the village of Robotyn. On this front, there is an advance of hundreds of metres. Offensive operations continue on the Burdiansk front. We have already entered the first line of occupiers and the first line is very difficult. But our military is pushing through. We are moving forward and this movement is slowed down by minefields and lack of aviation. Kuzmin stressed. Kuzmin adds, there is a high density of mines and engineering barriers of Russians on this front. The deputy commander said that there are more and more trained Russians. Russian troops pull up reserves from the second line of defence, including marines, paratroopers and special forces. Ukraine is prioritising its counter-offensive operations in the country south, while for Russia the main direction for assaults is the east. The majority of Russian resources are currently concentrated near Kupyansk, Kharkiv Oblast. As Moscow seeks to retake, the territory is liberated by Ukrainian forces last fall.
