Ukraine's army chief has visited Ukrainian troops fighting inside Russia as battles rage on in Kursk and along the hundreds of miles of frontlines snaking through eastern Ukraine ahead of the onset of winter.
"I worked with military units and subdivisions operating in the Sumy and Kursk regions," General Oleksandr Syrskyi said in a post to messaging app Telegram on Sunday. "I worked directly at the brigades' command posts. I listened to the brigade commanders and their proposals for further actions, and assisted in resolving problematic issues."
The northeastern Ukrainian Sumy region borders the southern Russian region of Kursk, where Ukrainian forces are months into a surprise incursion that Moscow's troops have struggled to quickly peel back.
"Despite all the enemy's attempts to seize the initiative, the situation remains under our control," Syrskyi said.
