Ukrainian forces control 50 km² of Russia’s Kursk region – Estonian intelligence

The Armed Forces of Ukraine remain present in part of Russia’s Kursk region — approximately 50 square kilometers.
This was reported by Lieutenant Colonel Janek Kesselmann, Deputy Head of the Estonian Defence Forces Intelligence Centre, Censor.NET reports, citing ERR.
"According to our assessment, around 50 square kilometres are under the control of the Ukrainian Armed Forces," he stated.
Kesselmann emphasized that Ukraine is not interested in and cannot withdraw its forces from Kursk and this section of the border in general. At the same time, Ukrainian troops are exerting pressure in other areas in the north, particularly in the direction of Belgorod, to tie up the Russian army:
"This prevents the Russian Federation from strengthening the main direction of the attack or opening a new direction," the lieutenant colonel added.
According to Kesselmann, the highest intensity of fighting over the past week was observed in Donetsk region.
He also drew attention to strikes on deep rear targets of both sides. In particular, on April 6, Russia launched strikes from the Black Sea Fleet ships, and Ukraine responded with strikes on an explosives plant in the Samara region and a fiber optic plant in Saransk:
"Fiber optics have become a critical component for UAVs used at the tactical level," Kesselmann explained.
