Russian forces tried to use an underground gas infrastructure to advance and launch attacks, President Zelensky said. He reported that Ukrainian forces have successfully adapted this tactic, making it more sophisticated and technologically advanced. "Our activity in the Kofiansk sector is significant. Drapati, Ovolensky and Palisa provided updates on the initial results and progress of Operation Wells, which was conducted by the 2nd National Guard Corps, Hartia Unit. More than 100 Russian troops have already been eliminated, and more than 30 have been taken prisoner. The advanced underground extends over more than 15 kilometers," the head of state noted.
