Troops and equipment from a Russian battalion tactical group (BTG) were destroyed by Kyiv's forces fighting a counteroffensive in the southern Kherson region, an adviser to Ukrainian President Volodymyr Zelensky, has said.

Oleksiy Arestovych said that Ukrainian troops capitalized on tactical errors made by Russian forces who were trying to advance near the village of Inhulets by the river of the same name.

He said that Russian forces were about to attack using air defense, tanks and other equipment but coordination from Moscow's military command was conducted "very poorly."

And our [troops] again caught them with their pants down. I won't say it took place on the night before the offensive, but a very short time before it, when they were in their most vulnerable position," Arestovych told YouTube channel Feygin Live on Thursday, hosted by lawyer and former Russian opposition politician, Mark Feygin.

The Russian Ministry of Defense, which Newsweek contacted for comment, did not mention the Kherson region in its daily update on Thursday although it rarely acknowledges military setbacks.
